New fluoroionophores for metal cations based on benzo[d]oxazol-5-yl-alanine bearing pyrrole and imidazole

Highly emissive heterocyclic alanines bearing a benzo[d]oxazolyl unit functionalised with pyrrole and imidazole at the side chain were synthesised and evaluated as fluorimetric chemosensors for different anions and metal cations. The results obtained by UV-Vis and fluorescence titrations as well as H-1 NMR titrations indicate that there is a strong interaction through the donor N and O atoms at the side chain of the benzoxazolyl-alanines, with high selectivity towards Cu2+ and Pd2+ in a ligand-to-metal complex with 1:2 stoichiometry, and association constants were calculated for some ions. The photophysical and ion sensing properties of these unnatural amino acids suggest that they can be used to obtain bioinspired frameworks for metal ion recognition such as peptides/proteins with chemosensory/probing ability.

Polymer Structure Prediction from First Principles

Developing a large database of polymers structures and properties, for which suitable polymer structural models are a prerequisite, is critical for polymer informatics. We present a simple strategy, referred to as polymer structure predictor (PSP), for predicting the crystal structural models of linear polymers, given their chain-level atomic connectivity information. The PSP, which was designed specifically for polymers, relies on properly defining and sampling the configuration space. Using this approach, we have successfully recovered eight known crystal structures of six common linear polymers, including polyethylene, polyvinylidene fluoride, poly(vinyl chloride), poly(p-phenylene sulfide), polyacrylonitrile, and poly-2,5-benzoxazole, while discovering some new stable structures of three of them, i.e., polyvinylidene fluoride, polyacrylonitrile, and poly(p-phenylene sulfide). The PSP is very simple, highly scalable, suitable for automatic workflows, and comparable to the best major structure prediction method in terms of efficiency in polymer crystal structure prediction. Although challenges in comprehensively accounting for possible chain-level conformations remain, the PSP will be very useful in efficiently generating polymer data and strengthening the emerging polymer informatics ecosystems.

A through-bond energy transfer-based ratiometric fluorescent pH probe: For extreme acidity and extreme alkaline detection with large emission shifts

A ratiometric fluorescence pH probe 1 based on through-bond energy transfer (TBET) with a 2-(2-hydroxyphenyl)benzoxazole (HBO) as donor and a Rhodamine derivative as acceptor is developed through simple condensation reaction. The probe exhibits a ratiometric fluorescence emission (I-593/I-422) characteristics and linear response to extreme acidity range of 5.00-2.88, and a ratiometric fluorescence emission (I-555/I-422) characteristics and linear response to extreme alkaline range of 10.00-13.78, respectively. Moreover, 1 possesses highly selective response to pH over metal ions, good reversibility and excellent photostability. Probe 1 is cellpermeable and can distinguish near pH 5.55 fluctuations in Hela cells.

Constructing Gas Molecule Transport Channels in Thermally Rearranged Multiblock Poly(benzoxazole-co-imide) Membranes for Effective CO2/CH4 Separation

A series of multiblock poly(benzoxazole-co-imide) (PBOI) membranes were prepared via thermal rearrangement of their corresponding multiblock copolyimide (CPI) precursors based on 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA), 2,2′-bis(3-amino-4-hydroxy-phenyl) hexafluoropropane (APAF), and 5-amino-2-(4-aminobenzene) benzimidazole (BIA). For ortho-hydroxy-functionalized CPI precursors, the difference in stacking behavior between the 6FDA-APAF and 6FDA-BIA blocks results in a weak microphase separation in CPI membranes, whereas the random precursor exhibits a homogeneous morphology, which has been identified by dynamic mechanical analysis, small-angle X-ray scattering, and atomic force microscopy analysis. After the subsequent thermal rearrangement at 420 degrees C, the microphase separation was also observed in the multiblock poly(benzoxazole-coimide) (TR-PBOI) membranes with an enlarged domain size. The impacts of the sequence structure on the membrane phase-separation behavior and mechanical and gas separation properties were investigated. Comparatively, an obvious increase in the CO2/CH4 gas separation property from the random to TR-PBOI membranes was observed. Specially, the resultant multiblock A(40)B(40)-TR-420 membrane possesses a CO2 permeability of 92 Barrer and a CO2/CH4 selectivity of 54.7, which is substantially higher than the values of the random-PBOI-420 membrane (CO2 permeability of 40.2 Barrer and CO2/CH4 of 58) and those of recently reported TR-PBOI membranes. The appealing gas separation performance of the multiblock PBOI membranes can be attributed to their microphase-separated morphology, in which continuous percolating microcavities formed in the thermal rearrangement reaction provide transport channels for gas molecules. The present study demonstrates that the modification of the micromorphological structure of membranes can effectively tune their final gas separation properties.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 14814-09-6, you can contact me at any time and look forward to more communication. Quality Control of 3-Mercaptopropyltriethoxysilane.

Thermosets containing benzoxazole units: Liquid-crystalline behavior and thermal conductivity

A series of liquid-crystalline (LC) thermosetting monomers containing benzoxazole (BO) units were synthesized to evaluate the thermal conductivities (lambda) of their cured resins. A BO-containing bisnadiimide system showed LC behavior during the heating process. However, the thermal cure of the bisnadiimide provided a film without optical anisotropy; consequently, the cured film exhibited normal levels of thermal diffusivity (alpha) and thermal conductivity (lambda). The disappearance of the optically anisotropic ordered structures during thermal curing is likely related to the temperature gaps between the cure reaction ranges and LC ranges (T-cure-T-LC gap). In addition, epoxy resins consisting of bisepoxides and BO-containing diamines were investigated because of their high flexibility in terms of molecular design that can be used to reduce the T-cure-T-LC gap. The combination of a terephthalylidene-type bisepoxide and BO-containing diamine with a controlled flexible chain length resulted in the smallest T-cure-T-LC gap among the epoxy resin systems examined herein. The cured epoxy resin film exhibited an appreciably increased lambda value (0.257 W m(-1) K-1) in the Z direction. This indicated the importance of the T-cure-T-LC gap for enhancing the alpha and lambda values of the cured films. This epoxy resin system was cured under a continuous DC electric field during polarizing optical microscopy. A prompt response with deformation of the LC domains was observed in harmony with temporal ON/OFF switching of the DC power supply. As expected, the cured film exhibited a significantly enhanced lambda value (0.488 W m(-1) K-1) in the Z direction.

Synthesis and structure of novel Si-substituted silylpropyl derivatives of 2-mercaptobenzoxazole and 2-mercaptobenzothiazole

A previously unknown carbofunctional (trimethoxysilyl)propyl derivative of the 2-mercaptobenzoxazole, C6H4NOCS(CH2)(3)Si(OMe)(3), containing a tetracoordinated silicon atom was synthesized by nucleophilic substitution of the chlorine atom in the (3-chloropropyl)-trimethoxysilane with the benzoxazol-2-ylsulfanyl group. The reaction of 2-[(trimethoxysilyl)propylsulfanyl]benzoxazole or -benzothiazole with boron trifluoride etherate led to a previously unknown hydrolytically unstable Si-fluoropropyl derivatives of 2-mercaptobenzoxazole or 2-mercaptobenzothiazole, C6H4N(Y)CS(CH2)(3)SiF3 (Y = O, S). By transesterification of 2-[(trimethoxysilyl)-propylsulfanyl]benzoxazole by tris(2-hydroxyethyl)amine, a new silatranylpropyl derivative of 2-mercaptobenzoxazole containing an intramolecular coordination bond N -> Si and a pentacoordinated silicon atom, C6H4NOCS(CH2)(3)Si(OCH2CH2)(3)N, was obtained.

New non-protienogenic fluorescent amino acids: Benzoxazol-5-yl-alanine derivatives containing acetylene unit. Synthesis, spectral and photophysical properties

New derivatives of non-proteinogenic amino acids benzoxazol-5-yl-alanine containing substituted acetylene derivative were synthesized according to Sonogashira coupling reaction. All of the obtained compounds are fluorescent. They are characterized by high or moderate molar absorption coefficients, large Stokes shifts, high fluorescence quantum yields and very high brightness. All of these parameters as well as the positions of absorption and emission bands depend on the type and size of substituent and the solvent polarity. Their high brightness enables working with low concentrations, simple and easy detection of spectral absorption and fluorescence analyzes. Moreover, amino acid part of studied compounds allow to use them as covalently attached to a peptide or protein fluorescent probes in biological system studies.
