Abstract

Abstract: In this paper, a series of α-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. Graphical abstract: Image 1 Highlights: Their fluorescence behaviors were modulated by the bonder between benzene rings. Local excited state or charge transfer state luminescence was related with dihedral angle between donor and acceptor. The luminescent wavelengths of synthesized compounds were ranged from 456 nm to 621 nm.
