Abstract
Optical properties of semiconductor structures based on clam-shell phthalocyanine complexes have been studied by Fourier Transform Infrared Spectrometry. Transmission spectra of metal-free monophthalocyanine, bis-phthalocyanine of Eu and Eu di-tris-phthalocyanine organic semiconductors were have been obtained and analyzed. Comparison of spectral data from different clam-shell complexes revealed that magnetic f-f interaction of Eu atoms increase the energy of vibronic states which is clearly indicated by the spectral shift of absorption lines position. A new set of absorption lines in the 2360÷2341 cm -1 range was observed. It was suggested that these lines correspond to vibrations of orto-bis(oximetil)phenol group. It was found that vibronic modes of the phtalocyanine-ring reveal several absorption lines with spectral coordinates 526 cm -1 , 502 cm -1 , 484 cm -1 , 467 cm -1 in the far infrared region.
