We have used functionalized carbazoles and indenoquonoxalines as the main building units and enthynyl groups as the pi-linkages to construct two novel dendritic fluorophores and studied their degenerate multi-photon absorption properties in both the solution phase and the neat-film state within femtosecond and nanosecond regions. In our experiments, these model compounds are found to manifest strong and widely dispersed two-photon absorption as well as effective power-limiting properties against ultra-short laser pulses in the near-IR region. In addition, both chromophores exhibit medium to strong three-photon-induced fluorescence, indicating such scaffold may serve as a reference structural motif for the development of three-photon materials.

Poly(arylamine)s were synthesized by poly-condensation of 4-n-octylaniline with 4,4′-dibromobiphenyl using the Buchwald-Hartwig aryl amination. Both the NH and the Br end groups were properly modified upon addition of an end-capping reagent in an appropriate ratio. The synthesized polymers contained many impurities, such as Pd, Br, and Cl, which decrease organic light-emitting diode performance. An investigation to reduce the impurities in the polymer showed that the purification solvent plays the key role in reducing the concentration of impurities in the polymer; purification with a nonchlorinated solvent, anisole, provided a highly pure poly(arylamine) even with a simple purification procedure. Moreover, the highly purified polymer material improved carrier mobility in hole-only devices.

Chemoselective C-H arylations were accomplished through micellar catalysis by a versatile single-component ruthenium catalyst. The strategy provided expedient access to C-H-arylated ferrocenes with wide functional-group tolerance and ample scope through weak chelation assistance. The sustainability of the C-H arylation was demonstrated by outstanding atom-economy and recycling studies. Detailed computational studies provided support for a facile C-H activation through thioketone assistance.

Two novel copolymers of 4-thieno[3,2-b]thiophen-3-ylbenzonitrile (TT-CN), possessing electron withdrawing cyano moiety, with anthracene (P1) and biphenyl (P2) were prepared via Suzuki coupling. Optic, electronic, and thermal properties of the copolymers were investigated through UV-Vis spectroscopy, cyclic voltammetry, gel permeation chromatography, and thermal gravimetric analysis. The polymers with anthracene and biphenyl had electronic band gaps of 2.01 and 1.90 eV, respectively. Both polymers demonstrated excellent large Stokes shifts of 101 (anthracene) and 105 nm (biphenyl) as well as very good thermal properties. As they had good optical, electronic, and thermal properties, they are promising candidates for electronic applications.

Two high-resolution mass spectrometers (HRMS) with different analyzer technology, Orbitrap and hybrid quadrupole time-of-flight (QTOF), were compared with a low-resolution mass spectrometer, quadrupole, to analyse a set of 35 difficult allergens. These difficult allergens are commonly coeluted fragrance allergens with matrix compounds, using standard gas chromatography-mass spectrometer conditions, from the extended list of the Scientific Committee on Consumer Safety (SCCS). Although the fundamental role of chromatographic separation has been demonstrated many times, the aim of this work is to demonstrate the benefits of high-resolution. The added value of high-resolution was illustrated in both a qualitative and a quantitative way. For qualitative aspect, the high resolution extracted ion signals of these two detectors were compared with the low-resolution extracted ion signals. About 50% of the coeluted cases observed with the low-resolution detector are easily resolved by the two high-resolution detectors. For the quantitative aspect, an accuracy profile methodology and a performance metric were used to propose an overall evaluation. The Orbitrap mass spectrometer demonstrated a better overall performance, while the QTOF presented similar or even lower quantification performances than the quadrupole on the set of analysed fragrances.

The space integration of the lithiation of aryl halides, the borylation of aryllithiums, and Suzuki-Miyaura coupling using a Pd catalyst supported by a polymer monolith flow reactor without using an intentionally added base was achieved. To scale up the process, a series connection of the monolith Pd reactor was examined. To suppress the increase in the pressure drop caused by the series connection, a monolith reactor having larger pore sizes was developed by varying the temperature of the monolith preparation. The monolithic Pd reactor having larger pore sizes enabled Suzuki-Miyaura coupling at a higher flow rate because of a lower pressure drop and, therefore, an increase in productivity. The present study indicates that series connection of the reactors with a higher flow rate serves as a good method for increasing the productivity without decreasing the yields.

Radical cations of bis(dianisylamino)-terminated oligo(p-phenylene)s (OPPs) with up to five phenyl moieties were characterized by means of UV/Vis-NIR and variable-temperature ESR spectroscopy to investigate the bridge-length-dependence on intramolecular charge/spin self-exchange between two nitrogen redox-active centers. Additionally, a comparative study between bis(dianisylamine)-based mixed-valence (MV) radical cations connected by p-terphenylene and hexa-peri-hexabenzocoronene (HBC) pi-bridging units also provided information on the influence of extended pi-conjugation over the OPP-bridge due to the planarization between adjacent phenylene units on the strength of electronic coupling. The present study on a homologous series of organic MV systems clarifies the attenuation factor through the OPP-bridge and the linear relationship between the electrochemical potential splitting and the electronic coupling in the region of intermediate-to-weak electronic coupling regime.

Two new M8L4 tetrafacial nanotubes (T1 and T3) of different lengths have been synthesized in water using ligands L1 and L2, respectively, with acceptor cis-[(dch)Pt(NO3)(2)] (M) using coordination-driven self-assembly [where dch is 1,2-diaminocyclohexane, L1 is 1,4-di(pyrimidin-5-yl)benzene, and L2 is 4,4′- di(pyrimidin-5-yl)-1,1′-biphenyl]. In addition to complex T1, a tetrahedral cage of composition [M-12(L1)(6)] (T2) was also formed in the self-assembly reaction of ligand L1 with cis-[(dch)Pt(NO3)(2)]. The precise composition of the products (T1 and T2) in solution was confirmed by H-1 NMR and ESI-MS. Pure tube T1 was separated out by a crystallization technique and fully characterized by 1H NMR and X-ray diffraction. Temperature- and concentration-dependent NMR studies indicated no equilibrium between T1 and T2 in the solution phase, and the proportion of T1 and T2 in the mixture depends on the temperature of the reaction. In contrast to ligand L1, the self-assembly of the longer ligand, L2, with cis-[(dch)Pt(NO3)(2)] gave only tetrafacial tube [M-8(L-2)(4)] (T3) without any tetrahedral cage.

A series of Pd/Fe2O3 nanohybrids with low metal content supported with Amberlite resin formate (Pd/Fe2O3@ARF) was prepared and characterized by FTIR, XRD, XPS, EELS, SEM-EDAX, and HRTEM. The coexistence of mainly crystalline Pd and Fe2O3 nanoparticles (NPs) of average size similar to 4-5 nm in the resin matrix was confirmed. These nanohybrids were used for hydrodehalogenation of polyhaloar-omatics using NaBH4 as a reducing agent in water. Notably, the composite Pd/Fe2O3@ARF-110 exhibits excellent catalytic performance in the hydrodehalogenation of different haloar-omatics. High TOF (in comparison to other related heterogeneous catalysts), recydability, and chemoselectivity between halide and C = C bond make this nanohybrid catalyst very attractive for the degradation of persistent organic pollutants originated from industries. The experimental observations and other analytical studies suggest that the enhanced catalytic activity could be due to strong interactions between Fe2O3 and Pd NPs that facilitate the cleavage of B-H bond and subsequent hydride generation.

We report on the first experimental and theoretical investigations of ultrafast intramolecular energy transfer for a novel class of highly luminescent materials – nanostructured organosilicon luminophores (NOLs). For this purpose we designed, synthesized and investigated a NOL, (POPOP)Si-2(3Ph-EH)(6), consisting of six p-terphenyl (3Ph) donor and 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP) acceptor luminophores – well-known laser dyes widely used in plastic scintillators as an activator and a spectral shifter, respectively. The NOL shows excellent optical properties – molar absorption coefficient up to 2.6 x 10(5) L mol(-1) cm(-1), photoluminescence quantum yield up to 96% and pseudo Stokes shift of 100 nm. Its intramolecular energy transfer efficiency determined from steady-state optical measurements was found to be 93%, while the excitation lifetime was less than 1 ns. For deeper understanding of the processes of intramolecular energy transfer within NOLs, ultrafast spectroscopy investigations of the NOL, model donor and acceptor luminophores were performed for the first time for this class of compounds. It was found that the time constant of the energy transfer from donor to acceptor luminophores within the NOL is tau(1) = 105 fs, which is significantly faster than the vibrational relaxation within the donor (ca. 400 fs). Based on these findings, a kinetic scheme of the electronic excitation energy deactivation processes in the NOL was developed. The results obtained not only directly prove that the mechanism of energy transfer within the NOLs is based on Forster resonance energy transfer of the excitation energy from donor to acceptor luminophores, but also highlight the advantages of NOLs and NOL-based materials for future photonics applications – fast and efficient plastic scintillators, scintillating fibers and other spectral shifting optical materials.
