In our study, we demonstrate the splitting effect of long-wavelength bands in absorption spectra (excitation of fluorescence) of the series of Zn(II), Ti(IV), Zr(IV) and Hf(IV) phthalocyanines at low temperatures. The effect has been explained by the shift of metal ion out of the plane of phthalocyanine macrocycle, the transformation of macrocycle to nonplanar “dome” conformation and additional loss the high symmetry of macrocycle.
