摘要：

Langmuir-Blodgett (LB) films of dysprosium octa-tert-butylphthalocyanine complexes (DyPc2t) were fabricated on various substrates and characterized using vibrational and electronic spectroscopy. The adsorption of electron acceptor molecules by DyPc2t LB films is reported here for NO2, Br2 and I2. The formation of a chemisorbed state with detectable charge transfer between the phthalocyanine (Pc) complex and electron accepting molecules was observed. The hyperconjugation effect of the alkyl substituents, which increases the electron density in the Pc ring, strongly affects the chemisorption process and reduces and rate of desorption.
