摘要：

A new phthalocyanine, tetra-{4-[5-(4-tert-butyl-phenyl)-[1,3,4]oxadiazol-2-yl]-phenoxyl-zincphthalocyanine (TOPc) was synthesized and its Langmuir-Blodgett (LB) film was fabricated and characterized by ultraviolet-visible (UV-vis) absorption and polarized UV-vis absorption spectra. The results show that the tilt angle of TOPc molecules on substrate is about 32. Field-effect transistor incorporating with LB film of TOPc as a semiconductor layer was fabricated. A mobility of 1.1 x 10(-4) cm(2) V-1 s(-1) and an on/off ratio up to 10(3) have been achieved. (c) 2006 Elsevier B.V. All rights reserved.
