In this study, a series of alpha-cyano-1,4-diphenylbutadiene derivatives containing triphenylamine structure were designed and synthesized. By changing the connection mode, the fluorescent wavelengths of the compounds were further regulated.
ABS T R A C T In this paper, a series of alpha-cyano-1,4-diphenylbutadiene derivatives containing triphenylamine structure were designed and synthesized. By changing the connection mode of the terminal diphenylamine, the angle between the donor and the acceptor was adjusted to further regulate the fluorescent wavelengths of 1a-1h from 456 nm to 621 nm in solution and 515 nm-614 nm in solid states.
