Abstract

original image

The preparation of PEDOT single- crystal nanoneedles using an interfacial polymerization process with simultaneous crystallization is reported. The absence of external dopants and crystallization during chain growth leads to closely packed crystals. These nanoneedles show a novel switching behavior with a response time in milliseconds (see figure).
