Anthraceneis a solid polycyclic aromatic hydrocarbon 8 A9: offormula C $ 9 $2 consistin# of three fused ben;ene rin#s

The molecular planarity and ri#idity nature of the

anthracene buildin# bloc7' the correspondin# copolymersshowed #ood char#e transportin# properties' while thewea7 donatin# property of anthracene resulted inpolymers with a deep 9"!" level' which is favorable toproduce CSs with 9i#h = oc and C3s/

A ma>or problem forusin# unsubstituted anthracene toconstruct the copolymer is its poor solution

Conclusion3 Donor−acceptor precursor copolymers based

on anthracene with thermally cleavable #rouphave been synthesi;ed

3 All precursor copolymers can be completelyconverted into the tar#et semiconductin#

copolymers with #ood coplanarity and ri#iditythrou#h heatin# at moderate temperatures

3 niform ?lms can be formed due to the #oodsolubility of the precursor copolymers incommon solvents/

3 SCs devices were successfully fabricatedthrou#h applyin# thermal annealin# treatmenton the polymer fullerene blend ?lms and thehi#hest C3 of 0/$,) was achieved based oncopolymer C"A39D with shorter side

chains on the D unit/
