摘要：

Conjugated polymer single crystals and nanowires show advantages for the study of intrinsic charge transport in conjugated polymers and achieve high device performance. However, preparation of conjugated polymer single crystals and nanowires, especially donor-acceptor (D-A) conjugated polymers, is challenging. In this review, the structural features of conjugated polymers are first described. Then, the mechanism of conjugated polymer crystallization in terms of thermodynamic equilibrium state, nucleation, and growth is discussed. Single crystals of poly(alkylthiophene)s (P3ATs) and nanowires of both P3ATs and D-A conjugated polymers are subsequently reviewed. Growth kinetics are a key issue in growing D-A-conjugated polymer crystals. Finally, the device performance based on conjugated polymer single crystals and nanowires is summarized.
