Conjugated microporous polymers (CMPs) synthesised in different solvents give different surface areas dependent on the solvent choice. No one solvent results in a high surface area across a range of different CMP materials. Here, we present an investigation into how the porosity of CMPs is affected by solvent polarity. It is seen that the trends differ depending on the respective monomer dipole moments and whether hydrogen bonding groups are present in the monomers and are able to interact with the respective solventviahydrogen bonding. It is believed that this methodology could be used to influence future materials design of both structure and synthesis strategy.

An article Reversible Multicomponent AND Gate Triggered by Stoichiometric Chemical Pulses Commands the Self-Assembly and Actuation of Catalytic Machinery WOS:000529959000022 published article about MOLECULAR LOGIC GATES; NETWORKING NANOSWITCHES; SIGNAL AMPLIFICATION; ON/OFF CONTROL; COMMUNICATION; COORDINATION; DNA; CONSTRUCTION; INFORMATION; DEVICES in [Biswas, Pronay Kumar; Saha, Suchismita; Gaikwad, Sudhakar; Schmittel, Michael] Ctr Micro & Nanochem & Engn, Organ Chem 1, D-57068 Siegen, Germany in 2020, Cited 61.

The present work demonstrates the operation of a reversible supramolecular gate, i.e., an ensemble of various components linked by chemical communication, which is triggered by stoichiometric chemical inputs and by obeying the AND truth table delivers a stoichiometric chemical signal. The output triggers a series of events that finally set up a catalytic process. In detail, a three-component AND gate, composed of two distinct nanoswitches, a copper-loaded and an unloaded one {= state (0,0)}, was actuated with stoichiometric amounts of two inputs (IN-1 = Zn2+, IN-2 = Hg2+) generating copper(I) ions as output in state (1,1). The utility of this information processing was highlighted by using the copper(I) output for triggering the self-assembly of the four-component rotor ROT-2 through metal translocation. In the presence of suitable reactants, ROT-2 acted as a catalytic machinery catalyzing a click reaction (= signal amplification). Verification of the functioning of the AND gate in a mixture of 12 components was thus accomplished by monitoring formation of the click product. Due to the stoichiometric design, the gate was reset to state (0,0) by adding hexacyclen and reactivated by adding inputs IN-1 and IN-2 alike in the first cycle.

An article Acyclic diaminocarbene-based Thiele, Chichibabin, and Muller hydrocarbons WOS:000588192000013 published article about BIS(TRIARYLAMINE) DICATIONS; BUILDING-BLOCKS; DIRADICALOIDS; LIGANDS; ANALOGS; CARBENES; RADICALS; SINGLET in [Maiti, Avijit; Jana, Anukul] Tata Inst Fundamental Res Hyderabad, Hyderabad 500046, Telangana, India; [Chandra, Shubhadeep; Sarkar, Biprajit] Univ Stuttgart, Fak Chem, Lehrstuhl Anorgan Koordinationschem, Inst Anorgan Chem, Pfaffenwaldring 55, D-70569 Stuttgart, Germany in 2020, Cited 54.

Thiele, Chichibabin and Muller hydrocarbons are considered as classical Kekule diradicaloids. Herein we report the synthesis and characterization of acyclic diaminocarbene (ADC)-based Thiele, Chichibabin, and Muller hydrocarbons. The calculated singlet-triplet energy gaps are Delta ES-T = -27.96, -3.70, -0.37 kcal mol(-1), respectively, and gradually decrease with the increasing length of the pi-conjugated spacer (p-phenylene vs. p,p ‘-biphenylene vs. p,p ”-terphenylene) between the two ADC-scaffolds. In agreement with the calculations, we also experimentally observed the enhancement of paramagnetic diradical character as a function of the length of the pi-conjugated spacer. ADC-based Thiele’s hydrocarbon is EPR silent and exhibits very well resolved NMR spectra, whereas ADC-based Muller’s hydrocarbon displays EPR signals and featureless NMR spectra at room temperature. The spacer also has a strong influence on the UV-Vis-NIR spectra of these compounds. Considering that our methodology is modular, these results provide a convenient platform for the synthesis of an electronically modified new class of carbon-centered Kekule diradicaloids.

[n]Cycloparaphenylenes, or carbon nanohoops, are unique conjugated macrocycles with radially oriented pi-systems similar to those in carbon nanotubes. The centrosymmetric nature and conformational rigidity of these molecules lead to unusual size-dependent photophysical characteristics. To investigate these effects further and expand the family of possible structures, a new class of related carbon nanohoops with broken symmetry is disclosed. In these structures, referred to as meta[n]cycloparaphenylenes, a single carbon-carbon bond is shifted by one position in order to break the centrosymmetric nature of the parent [n]cycloparaphenylenes. Advantageously, the symmetry breaking leads to bright emission in the smaller nanohoops, which are typically non-fluorescent due to optical selection rules. Moreover, this simple structural manipulation retains one of the most unique features of the nanohoop structures-size dependent emissive properties with relatively large extinction coefficients and quantum yields. Inspired by earlier theoretical work by Tretiak and co-workers, this joint synthetic, photophysical, and theoretical study provides further design principles to manipulate the optical properties of this growing class of molecules with radially oriented pi-systems.

Reported here is a molecule-Lego synthetic strategy for macrocycles with functional skeletons, involving one-pot and high-yielding condensation between bis(2,4-dimethoxyphenyl)arene monomers and paraformaldehyde. By changing the blocks, variously functional units (naphthalene, pyrene, anthraquinone, porphyrin, etc.) can be conveniently introduced into the backbone of macrocycles. Interestingly, the macrocyclization can be tuned by the geometrical configuration of monomeric blocks. Linear (180 degrees) monomer yield cyclic trimers and pentamers, while V-shaped (120 degrees, 90 degrees and 60 degrees) monomers tend to form dimers. More significantly, even heterogeneous macrocycles are obtained in moderate yield by co-oligomerization of different monomers. This series of macrocycles have the potential to be prosperous in the near future.

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.

This study intends to design and prepare a new magnetic copper catalyst and its activity was assessed by carbon-carbon coupling reactions. For this purpose, 1-[3-(trimethoxysilyl) propyl] urea (TMSPU), hydrazine and CuI were used sequentially to modify Fe3O4@SiO2 core-shell magnetic nanoparticles to obtain an efficient magnetic transition metal catalyst. Various analytical techniques were used to characterize the catalyst to show that the achieved structure and its properties are well-suited for coupling reactions. Finally, Mizoroki-Heck and Ullmann coupling reactions were performed using Fe3O4@SiO2@PrNCu catalyst. The new catalyst offer simple synthetic procedure, convenient use for routine casework and low price. The Fe3O4@SiO2@PrNCu catalyst was easily separated by means of a permanent and ordinary magnet and the recovered catalyst was reused in six cycles without any significant loss of activity.
