Abstract

We have already reported a nanowire structure of bis-tetrathiafulvalenb (bis-TTF) annelated macrocycle - tetrafluorotetracyanoquinodimethane (F 4TCNQ)charge transfer complex formed by Langmuir-Blodgett (LB) technique. Nanowires oriented on the mica substrates forming an angle of 60 degree to each other recognizing hexagonal potassium array of mica surface. In the present study, we examined the conditions for obtaining well oriented nanowires and found that the nanowire orientation was quite sensitive to the temperature and potassium-ion concentration of subphase as well as the deposition speeds. By a slight change in conditions, a variety of nanowire morphology was observed on mica surface.
