The effects of introducing gallium and indium metals into phthalocyanine molecules were investigated via temperature and frequency dependent dielectric spectroscopy. The dielectric properties of Ga(III) and In(III) phthalocyanine pellets were measured at frequencies from 1 kHz to 1 MHz in the temperature range 300-530 K. The temperature dependence of the real part of the dielectric constant suggested that these compounds exhibit semiconductor behavior. The activation energy values were calculated from the Arrhenius plots at different frequencies. A distinct transition in these plots indicated the activation of ionic conductivity at higher temperatures.

Raman spectra of evaporated thin solid films (200 nm thickness) are studied using excitation frequencies in resonance and near resonance with the absorption red band of Al, Ga and in phthalocyanine.Depolarization ratios measured on thin films are also dis

The UV–Vis spectra for a set of MPcs (Mmetal, Pc?=?phthalocyanine ligand), i.e.: In(III)PcI (1), Hf(IV)PcI2Pht (Pht?=?phthalonitrile) (2), Sn(II)Pc (3), Sn(IV)PcI2 (4), and Ge(IV)PcI2 (5) have been examined in two solvents, O-donative acetylacetone, and non-coordinative benzene. The UV–Vis spectra in Hacac solution of 1,2 and 4,5 shows that the axially ligated iodine atoms are replaced by (acac)? anions of the solvent, whereas in 3 the oxygen donors of the solvent causing the auto-oxidation of Sn(II) to Sn(IV) ions and as a result the Sn(II)Pc is transformed into the Sn(IV)Pc(acac)2. The chloride complexes of the 1–5 compounds are formed at Hacac solution after acidification by hydrochloric acid, however each compound solution behaviors specifically. The UV–Vis spectra collected for the studied compounds at benzene solvent both before and after the solution acidization clearly indicate that the respective Q band character (besides 3) remains practically unchanged. The presence of the Cl? ions at the Sn(II)Pc solution in benzene results in the formation of Sn(IV)PcCl2.
