摘要：

Langmuir-Blodgett (LB) films of praseodymium, gadolinium, ytterbium diphthalocyanines and octa-tert-butyl praseodymium diphthalocyanine have been prepared on various substrates. The spectroscopic characterization (UV-Vis and Raman) of the films before and after being exposed to a tobacco smoke side stream (SS) has been carried out. The chemisorption of the SS to the lanthanide diphthalocyanines LB films reversibly forms a complex that reduces the oxidation state of the material. These changes can be followed in the electronic and vibrational spectra. The potential use as a tobacco smoke sensor is discussed.
