[Structural characterization of copper-phthalocyanine thin solid films by FTIR spectroscopy].
The structure of tris- (2, 4-di-t-amylpheoxy) - (8-quinolinoxy) copper phthalocyanine (CuPc) thin solid films has been characterized by Fourier transform infrared (FTIR) transmission, polarized transmission and reflection absorption (RA) spectroscopy. The following conclusions can be obtained from the above measurements: (1)in LB films, the hydrocarbon chains of CuPc are in hexagonal or pseudohexagonal subcell packing, the CH2 asymmetric vibrational vector is oriented with respect to the substrate surface and the RA spectroscopy can distinguish the two CH2 streching modes of benzene cycle; (2)in sublimed films, the molecules of CuPc are out of order.
