Chen, Ran; Wang, Lu; An, Zhongwei; Chen, Xinbing; Chen, Pei published an article in 2021. The article was titled 《Effect of π-conjugation units on the liquid crystal and photovoltaic performance of heterocyclic pyridine-based compounds》, and you may find the article in Liquid Crystals.Computed Properties of C7H5N The information in the text is summarized as follows:
A series of new calamitic liquid crystals (LCs), 4-(5-((4-(2-(trans-4-n-alkyl- cyclohexyl)ethyl)phenyl)ethynyl)-thiophen-2-yl)pyridine comprising a cyclohexyl, a Ph and two heterocyclic (pyridine and thiophene) ring core system, terminal alkyl chain, ethane and acetylene linkers were synthesized and characterised. Their structures were confirmed by IR spectrometry (IR), NMR (NMR) and mass spectrometry (MS), and the LC properties were investigated through differential scanning calorimetry (DSC) and polarising optical microscopy (POM). Dye-sensitized solar cells (DSSCs) were assembled to evaluate the photovoltaic properties of these materials. Furthermore, three compounds and have successfully been utilized to study the effect of π-conjugation units on the LCs properties and photovoltaic performance. The results show that thienyl unit instead of Ph unit benefits photovoltaic performance, while it is not favorable to the stability of the nematic mesophase and birefringence. Meanwhile, DFT calculations of mol. conformation, frontier MO and dipole moment were used to correlate the exptl. findings.4-Ethynylpyridine(cas: 2510-22-7Computed Properties of C7H5N) was used in this study.
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Computed Properties of C7H5N
