Synthetic Route of C20H14N4On May 31, 2020, Chen, Hong-Shuo; Guo, Rui-Yun; Zhang, Qi-Ming; Liu, Yang-Sheng published an article in Monatshefte fuer Chemie. The article was 《Tunable solid-state photochromism based on proton and anion-controlled structural transformation of pyridinium-based organic small molecules》. The article mentions the following:
An organic mol. system with proton and anion-tunable photochromism properties based on a pyridinium derivative was developed. Through controlling the pH value and anion nature of the self-assembled systems, the novel three compounds displayed different photochromism behaviors. This work reveals that the introduction of addnl. groups into the mol. increases the diversity of the property of such complexes. In the experiment, the researchers used 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Synthetic Route of C20H14N4)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. Synthetic Route of C20H14N4
