摘要
The growth conditions of meso- and nanoscopic copper phthalocyanine quasi-1D structures, single crystalline whiskers and "nanowebs" were investigated on various technologically important substrates and were compared to existing literature. The synthesized morphologies were used to fabricate organic conductometric gas-sensing devices, and their sensitivity and selectivity toward NOx were investigated. The obtained results demonstrate excellent sensitivity and selectivity of these quasi-1D chemiresistors. Both the response time of the quasi-1D CuPc sensors and their overall gas sensing performance can be further enhanced by reducing the surface-to-bulk ratio of these nano- and meso-structures.
