摘要：

A novel asymmetrically substituted amphiphilic phthalocyanine, 1,4-di(2-hydroxyethoxyl)-8,9,16,17,23,24-hexapentyloxylphthalocyaninozinc (asy-PcZn), was synthesized. It can be deposited as well-ordered LB films. Significant structural changes of the films were observed by UV-vis absorption spectra and low-angle X-ray diffraction after the films were annealed at 150 degreesC. What is more interesting is that the initial conductance of the films in air decreases and the response signal to NH3 is weaker with longer response time after annealing compared with that of the unpretreated films.
