Abstract

Disclosed is a soft and hard multi-block polymer and its synthesis method, which comprises using substituted aromatic ring, acrylic acid, methacrylic acid, vinylcarbazole and caprolactone monomers as raw material, carrying out organic metal coupling and atom transfer free radical polymerization reaction, and synthesizing a series of block polymers comprising conjugated oligomers and flexible water soluble / oil soluble soft segments, which can be used as the luminescent layer of organic electroluminescent material (OLED) and biological fluorescence detector.

Description

technical field [0001] The invention belongs to the technical field of new electroluminescence materials and self-assembly materials, and specifically relates to a soft and hard multi-block polymer and a synthesis method thereof. technical background [0002] Due to the special properties of new organic photoluminescent materials such as conjugated polymers, such as: soluble, easy to process, easy to modify, etc., they have broad applications in organic light-emitting devices, field effect transistors, chemical and biological sensing. Application prospect. However, traditional conjugated polymers usually have chemical defects, which brings some difficulties to the study of the relationship between chemical structure and properties. The present invention synthesizes a conjugated oligomer with a fixed structure, and modifies it into a suitable initiator; introduces a modified group controllably by methods such as atom transfer radical polymerization (ATRP) or ring-opening pol...
