Enthalpically and Entropically Favorable Self-Assembly: Synthesis of C-4h-Symmetric Tetraazatetrathia[8]circulenes by Regioselective Introduction of Pyridine Rings
Self-assembly of pi-conjugated molecules in solution generally occurs owing to either an enthalpic or an entropic gain; however, designing pi-conjugated systems that simultaneously exhibit enthalpically and entropically favorable self-assembly behavior is challenging. Herein, the self-assembly behavior of tetraazatetrathia[8]circulenes is disclosed, which is driven by both enthalpy and entropy. Single-crystal X-ray diffraction analysis demonstrated that molecules of these tetraazatetrathia[8]circulenes form face-to-face stacked dimers with a 1D columnar structure owing to the circularly arranged dipole moments. Importantly, concentration- and temperature-dependent H-1 NMR spectra revealed that the formation of self-assemblies of tetraazatetrathia[8]circulenes in chloroform and methanol is favored by both enthalpic and entropic factors. The unique association behavior is due to the presence of sp(2)-hybridized nitrogen atoms, which weakly coordinate to the hydrogen atoms of these solvents and reduce the pi-electron density of the circulene cores.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 15471-17-7 is helpful to your research. Application In Synthesis of 3-(Pyridin-1-ium-1-yl)propane-1-sulfonate.
