摘要

Abstract

A rod-rod diblock copolymer (diBCP)

poly(3-hexylthiophene)-block-poly(furfuryl isocyanate) (P3HT-

-PFIC)

was synthesized through the anionic polymerization with an oxyanionic macroinitiator of P3HT. The properties of the diBCP (molecular weight

dispersity

composition

thermal stability

UV-visible absorption

and thin film morphology) were determined by various analytical methods. P3HT-

-PFIC was blended with C

in a toluene solution to prepare a thin film of binary electron donor/acceptor system. Such blending enabled partial conjugation of the two components by the Diels-Alder reaction between furan and C

at 60 °C for 3 h; the mixture was then spin-cast as a thin film

and annealed at 250 °C for 24 h. Tapping-mode atomic force microscopy (AFM) revealed that P3HT and C

domains had nanoscale interfaces without a large phase segregation. This result indicated that the microphase separation of C

-functionalized P3HT-

-PFIC preserved even at high temperature provided free C

molecules with channels to diffuse on the sides of P3HT domain

thus preventing the macroscopic crystallization of free C

through the interfacial stabilization.
