Title:
HYPERBRANCHED POLYPHENYL AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/226264
Kind Code:
A1
Abstract:
The present invention relates to the technical field of macromolecules, and relates to hyperbranched polyphenyl and a preparation method therefor and an application thereof. The preparation method for the hyperbranched polyphenyl in the present invention comprises the following step: in a protective atmosphere, performing polymerization reaction on a binary internal alkyne monomer in a solvent under the action of a catalyst, so as to obtain the hyperbranched polyphenyl. In the present invention, the monomer subjected to the polymerization reaction is an internal alkyne monomer, and the catalyst is a non-metal catalyst p-toluenesulfonic acid. Polymerization reaction conditions are simple, convenient and green, and the problem that the polymer performance is influenced by catalyst residues caused by the use of a metal catalyst in a traditional cyclotrimerization polymerization reaction is solved. According to the present invention, the hyperbranched polyphenyl has a relatively high fluorescence quantum yield in an aggregation state due to typical aggregation-induced emission (AIE) group tetraphenylethylene, and has a full-conjugated structure, so that the hyperbranched polyphenyl can be used as a chemical sensor and has an application prospect in polymer light-emitting diodes.
