Determination of charge transfer reaction of tri -(2,4 -di-t-amylphenoxy)-(8-quinolinolyl )copper phthalocyanine and 2-octadecyl-7,7,8,8-tetracyanoquinodimethane in Langmuir-Blodgett films

The charge transfer reaction of tri-(2,4-di-t-amylphenoxy)-(8-quinolinolyl) copper phthalocyanine (CuPc) and 2-octadecyl-7, 7, 8, 8-tetracyanoquinodimethane (C₁₈-TCNQ) in alternating and mixed Langmuir-Blodgett (LB) films was studied by using Fourier transform infrdred, UV-Vis spectroscopy and cyclic voltammetry. These results indicated that charge transfer reaction happened between CuPc and C₁₈-TCNQ in both LB films. The conductance measurement also showsed that conductivity of both LB films increased about three orders of magnitude than that of pure CuPc LB films.
