Abstract
The deposition of Langmuir-Blodgett films of an asymmetrically substituted copper phthalocyanine is reported. Capacitance and optical absorption data reveal that these films can be deposited in a reproducible manner; results are also presented showing the extreme sensitivity of their electrical conductivity to ambients such as nitrogen dioxide. The relatively fast recovery times, compared with those for gas detectors based on vacuum deposited phthalocyanine films, are attributed to the thinness and ordered nature of the LB film.
