Optical spectra of Cu porphin and VO porphin in single crystal triphenylene

摘要: Abstract Polarized optical absorption spectra of copper porphin and vanadyl in single crystals triphenylene have been obtained at room temperature, 77°K 4.2°K. Luminescence these samples are also reported. The gross features the two metalloporphins similar but spectral lines much sharper than those porphin, revealing more satellite structure. It is shown that central metal can substantially affect metalloporphyrin spectra, contrary to case broad band solution spectra. data consistent with molecules substitutional sites a crystal field reduction usual D 4 h symmetry 2 .
