In 2019,Photochemical & Photobiological Sciences included an article by Kumar, Girijesh; Guda, Ramu; Husain, Ahmad; Patra, Ranjan; Kirandeep; Kasula, Mamatha. Reference of 4-Cyanopyridine. The article was titled 《Synthesis and photophysical properties of pyridyl conjugated triazole appended naphthalenediimide derivatives》. The information in the text is summarized as follows:
A series of three substituted triazole appended naphthalenediimide (NDI)-derivatives, 2,7-bis(3,5-di(pyridin-X-yl)-4H-1,2,4-triazol-4-yl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraones (where X = 2, NDI-PyTz-1; 3, NDI-PyTz-2; and 4, NDI-PyTz-3), were designed, synthesized and well characterized using various anal. and spectroscopic techniques. All the three NDI-PyTz derivatives exhibited decent electronic properties as suggested by DFT, cyclic voltammetry and fluorescence studies. In particular, NDI-PyTz-1 demonstrated the generation of a stable anion radical [NDI-PyTz-1].-. In the part of experimental materials, we found many familiar compounds, such as 4-Cyanopyridine(cas: 100-48-1Reference of 4-Cyanopyridine)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Reference of 4-Cyanopyridine
