Abstract

The invention discloses an isoindigo conjugated polymer, a semiconductor CNT ink, a preparation method and an application thereof. The iso-indigo conjugated polymer comprises constituent units represented by the following formula: wherein R 1 Including any one of heteroalkyl, straight-chain and branched-chain alkyl with 1 to 20 carbons, R 2 Including any one of hydrogen atom, heteroalkyl, halogen atom, straight-chain or branched-chain alkyl with 1-20 carbons, Ar includes 1-4 five-membered or six-membered aromatic rings, five-membered or six-membered A conjugated unit consisting of any one or two or more of membered aromatic heterocycles and multi-membered aromatic condensed rings, n is selected from any integer between 2 and 500. The isoindigo conjugated polymer of the present invention can be specifically combined with semiconducting carbon nanotubes, so it can be used for highly selective separation of semiconducting carbon nanotubes in commercial carbon nanotubes, and can form high-purity semiconducting carbon nanotubes (CNT) ink, which can be used to build semiconductor devices with superior performance.
