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).
