溴(寡)吩噻嗪通过Beller氰化方案,在传导性或介电加热下,使用NMP作为溶剂,以高至非常高的产率合成了(寡)吩噻嗪基腈。它们的电子性质通过吸收和发射光谱法以及循环伏安法测定。氰基(低聚)吩噻嗪显示出较大的斯托克斯位移(5800–8300 cm -1)和大量的量子产率(11–27%)。由于氰基的吸电子特性,它们的可逆氧化电位在阳极上有很大的偏移。

nitriles were synthesized in good to very good yields from bromo (oligo)phenothiazines via the Beller cyanation protocol either under conductive or under dielectric heating using NMP as a solvent. Their electronicproperties were determined by absorption and emission spectroscopy and cyclic voltammetry. Cyano(oligo)phenothiazines display large Stokes-shifts (5800–8300 cm−1) and substantial quantum yields

Phenothiazinyl primary amines were synthesized in moderate to excellent yields from cyano (oligo)phenothiazines by reduction with LiAlH4 in diethyl ether or with nBuNBH4 in dichloromethane. All representatives show first reversible oxidation waves, they are UV absorbing and dimers emit blue-green light upon UV excitation with substantial quantum yield.
