“…toward the higher-wave-number side (redshift) with increase in substrate temperature; this may be due to variation in particle size. 36 With increase in substrate temperature, the intensity of the Raman peaks firstly increases, but at a higher temperature (413 K), it decreases; this may be due to the change in molecular symmetry connected with the metal ion position in the ZnPc molecule ring and its distortion of planarity against temperature.…”

The present paper reports the structural, optical and electrical properties of zinc phthalocyanine (ZnPc) thin films which were grown by the thermal evaporation technique at different substrate temperatures of 312, 363 and 413 K and dielectric response of sandwich geometry of ZnPc thin films have also been studied within frequency range 1 Hz-50 KHz. The crystal structures of these ZnPc films have been characterized using the X-ray diffraction technique. Raman spectra and photoluminescence have been recorded to study the molecular orientations in the ZnPc films for different substrate temperatures. The absorption spectra of the ZnPc films have shown two absorption bands -namely, the Soret band and Q-band. The activation energy values of these films have been determined to be lying in the range of 0·70-0·75 eV. Hole mobility values of ZnPc films have been calculated by using differential susceptance method. The capacitance and dielectric constant have been found to decrease with increase in frequency.

This work presents the ab initio study of transition-metal phthalocyanines within a PBE0 hybrid functional. The list of metal impurities includes manganese, iron, cobalt, nickel, copper, and zinc. All calculations of isolated molecules have been performed with the use of the projector augment-wave method. For iron phthalocyanine, we have performed four calculations with different values of the mixing parameter a (the value of the exact exchange) – 0, 1/4, 1/3, and 1/2. For all other molecules, the calculations have been performed for a = 1/4 and 1/3. The electronic structure parameters including the HOMO-LUMO energy gap, Fermi level, magnetization, and imaginary part of the dielectric function are presented and compared with available theoretical and experimental data. Manganese, iron, and cobalt phthalocyanines show a strong dependence of electronic properties on the value of the exact exchange interaction. In other molecules with nickel, copper, and zinc, this dependence is not significant.
