BENZODITHIOPHENE BASED COPOLYMER CONTAINING ISOINDOLINE-1,3-DIKETONE UNITS AND PREPARING METHOD AND APPLICATIONS THEREOF

摘要

The present invention relates to a benzodithiophene based copolymer containing isoindoline-1,3-diketone units and a preparing method and applications thereof. The polymer has a structural formula (I), wherein R₁ and R₂ are respectively selected from H or alkyl groups of C₁ to C₁₆; R₃ and R₄ are respectively selected from H, alkyl groups of C₁ to C₁₆, alkoxy groups of C₁ to C₁₆, or thiophene groups substituted by alkyl groups of C₁ to C₁₆; R₅ is selected from alkyl groups of C₁ to C₁₆; n is a natural number from 7 to 80. Applications of the benzodithiophene based copolymer containing isoindoline-1,3-diketone units in polymer solar cells, polymer organic light-emitting, polymer organic field effect transistors, polymer organic optical storage, polymer organic nonlinear materials or polymer organic laser are also provided.;
