Problems solved by technology
However, developing such systems remains challenging and has only a small number of literature reports
Furthermore, the molecular weight of these reported polymers is not very high (M w less than 20,000)
This may be limited by organic reactions with mild reaction conditions, high efficiency, and a wide range of reactions for AIEgen.

Abstract
A method involving the synthesis of poly(triphenylacrylonitrile) (PTPAN) comprising: polycoupling a dibromoarene, an internal diyne, and potassium ferrocyanide to obtain polycoupling dibromocyanide arene, internal diyne, and potassium ferrocyanide; and poly(triphenyl Acrylonitrile) (PTPAN), wherein the catalysis is carried out in dimethylacetamide at a specified temperature for a specified time under nitrogen. In addition, poly(triphenylacrylonitrile) (PTPAN) is a polymer and comprises a backbone structure of P1a-d / 2a-b / 3, wherein x and y are integers; wherein each R is independently selected from 1a, 1b, 1c and 1d; and wherein each R' is independently selected from the group consisting of 2a and 2b
Description
[0001] cross reference [0002] This application claims priority to Provisional U.S. Patent Application No. 62 / 496,291, filed October 13, 2016, filed by the present inventors and incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to the synthesis of polymers, and more particularly to the synthesis of poly(triphenylacrylonitrile) polymers by the one-pot three-component polyaryl cyanation reaction of diynes, and to poly(triphenylene Acrylonitrile) corresponding characteristics. Background technique [0004] The development of high-efficiency solid-state light-emitting materials has great significance in both academic and practical applications, so it has attracted much attention. However, when conventional luminescent materials form aggregates, their luminescence is usually partially quenched or even completely quenched, which has become a problem hindering the development of such materials. Since luminescent ma...
