The invention belongs to the field of organic photoelectric materials, and discloses preparation and application of a D-A type organic
molecular motor stimulation material. Based on a donor-
receptor configuration, the compound has the following structure: # imgabs0 #, wherein Ar is N, N-
dimethylaniline and a derivative thereof. According to the invention, an imino indole group is introduced to one end of a donor N, N-
dimethylaniline and a derivative thereof, so that a donor-
acceptor and a charge transfer state are constructed, and meanwhile, non-
radiative transition of molecules in an aggregation state is inhibited, so that the material is endowed with the property of AIE. In addition, due to the introduction of a C = N bond, the material shows an excellent
molecular motor characteristic, and has a photoresponse phenomenon of donor rotation under optical excitation. After the
trifluoroacetic acid proton-donating acidic material is added, the absorption spectrum is faded or the absorption
wavelength is subjected to
red shift. The material provided by the invention has efficient light and acid response capability, and has good application prospects in the aspects of
information storage, optical
signal transmission and information
encryption.
