Abstract

Charge transfer complex (CT complex) or electron donor-acceptor complex is defined as a material consisting of electrostatic attraction forces or chemical associations of two or more molecules or of different parts of one very large molecule.

Three organic π-π* charge transfer complexes formed from polynuclear aromatic hydrocrbons and picric acid such as anthracene picrate, phenanthrene picrate and pyrene picrate (Fig. 1 (a), (b) and (c)  respectively) were reorganized as thin films on quartz glass and 50 nm thick gold-coated glass substrates using the spin-coating method. For the characterization of the produced films, surface plasmon resonance (SPR) spectroscopy was used alongside UV-Vis spectroscopy. Subsequently, the films were exposed to benzene, chloroform, dicloromethane, acetone and ethanol vapors, and their sensor responses were examined in this study
