Abstract
Tetracyanoquinodimethane (TCNQ) derivatives, 2-fluoroTCNQ (F 1TCNQ), 2,5-difluoroTCNQ (F2TCNQ) and 2,5-dichloroTCNQ (Cl2TCNQ) were applied to form molecular nanowire structures of charge transfer complex with dialkyl derivative of bis-tetrathiafulvalene substituted macrocycle (1). When we used Cl2TCNQ, nanowire network structure was obtained as in the case of tetrafluoroTCNQ (F4TCNQ) previously reported. Although the nanowires were shorter compared with those of F4TCNQ complex and formed bundles, they oriented in specific directions recognizing the ionic array on mica surface. In the case of F 1TCNQ and F2TCNQ, we obtained nanowire structures almost identical with those of pure 1. The Cl2TCNQ formed an ionic complex with 1, in which donor units and Cl2TCNQ were in fully charge-transferred state. Reflecting the electronic structure, the conductivity of nanowires was estimated to be 2×10-4 S cm-1.
