Cyano modified triphenylmethyl radical skeletons: higher stability and efficiency.

This article presents the development of two new radical skeletons, BnBTM and bisBnTM, which offer improved stability and efficiency compared to the previously reported TTM radical. By incorporating cyano groups, these new skeletons exhibit enhanced photoluminescence quantum efficiency and longer-wavelength emission. The article provides detailed information on the synthesis, characterization, and photophysical properties of these radicals, highlighting their potential applications in fields such as organic light-emitting diodes and biosensing. The research was supported by the National Natural Science Foundation of China. [Extracted from the article]
