Abstract

The invention relates to a polymer with an aggregation-induced luminescent effect and a preparation method thereof, as well as a graphene composite material and a preparation method thereof. The polymer adopts structural general formula I, wherein n is from 8 to 20, and each of R1 and R2 is independently selected from C1-C6 alkyl, C1-C6 alkoxy or hydrogen. The polymer with the aggregation-induced luminescent effect is an AIE polymer containing a tetraphenylethylene functional group and adopting a novel structure; in the presence of the polymer, through in-situ reduction of graphene oxide, non-covalent bond modification of the graphene is achieved, and the graphene composite material soluble in an organic solvent is prepared; the composite material has an obvious AIE effect, and the AIE effect is higher than that of the polymer itself, so that the composite material has a wide application prospect in chemical sensors, bioprobes, solid state fluorescent materials and the like.

Description

technical field

[0001] The invention belongs to the technical field of organic light-emitting materials, and in particular relates to a polymer with aggregation-induced luminescence effect and a preparation method thereof, and also relates to a graphene composite material with aggregation-induced luminescence effect and a preparation method thereof. Background technique

[0002] In the research of photoelectric functional devices and sensors, fluorescent materials play an important role, but most fluorescent molecules have strong fluorescence in solution, and in the aggregate state or solid state, the intermolecular π-π interaction is enhanced, energy transfer occurs, and the formation of Exciplexes or excitoassociates consume the energy of the excited state, thereby weakening or even quenching the fluorescence (Aggregation-causedquenching, ACQ), which limits its application to a large extent. Therefore, how to effectively solve the ACQ effect is the focus and difficulty of ...
