Controlled polymerization of electron-deficient monomers: controlled preparation of n-type semiconducting polymers for organic electronics — •Anton Kiriy and Volodymyr Senkockyy — Leibniz Institut für Polymerforschung Dresden

Electron-conducting(n-type) main-chain pi-conjugated polymers are commonly prepared via well-established step-growth polycondensation protocols which enable limited control over polymerization. Chain-growth catalyst-transfer polycondensations were recently developed for controlled preparation of only hole-conducting (p-type) semiconducting polymers and block copolymers. In this contribution we present a new synthetic protocols that allows preparation of well-defined n-type semiconducting polymers. Specifically, we report on controlled polymerization of naphtalene-diimide based monomer resulting into corresponding n-type conjugated polymer (PNDIT2) with controlled molecular weight, relatively narrow polydispersities, and specific end-functions. Electron mobility of this polymer will be also presented (Senkovskyy, Kiriy, et al. J. Am. Chem. Soc. 2011, ASAP, ja-2011-08710x).
