However, much less interest has been shown in the investigation of bitriazine derivatives that are composed of two triazine rings. 10 Structurally, a 1,3,5-triazine unit is a typical electron-accepting unit, and introducing a 1,3,5-triazine unit into the backbone of conjugated compounds can usually improve the electron-injection and electron-transportation abilities of the compounds; such properties are useful for optoelectronic devices. For the bitriazine derivatives, their interesting ...
