Donor–acceptor co-assembled supramolecular nanofibers with high and well-balanced ambipolar charge transport properties under ambient conditions

Abstract

Single-bundle nanofiber based OFETs were fabricated from co-assembled supramolecular nanofibers which comprise TCAT and PDI-13, using a simple gelation method. The co-assembled supramolecular nanoarchitecture was fully characterized by means of optical microscopy, TEM, SEM, 2D-GIWAXS and so on. The devices exhibited typical ambipolar charge transport characteristics with very well-balanced hole and electron mobilities as well as high photoresponsivity under ambient conditions.
