First Time

The synthesis of tetrasubstituted zinc phthalocyanines bearing quinolinoxy groups are reported for the first time. The new compounds have been characterized by elemental analysis, IR, MS and electronic spectroscopy. The photophysical properties, such as the electronic absorption spectra and fluorescence spectra, have also been investigated and discussed together with the influence of substituent position and organic solvents on these properties. The introduction of quinolinoxy group to the Pc ring was found to affect these photophysical properties to some extent.

Argon Matrix

The absorption spectrum of CoCl2 molecules isolated in a nitrogen matrix and the fluorescence spectrum of CoCl2 molecules isolated in an argon matrix have been measured at liquid helium temperatures in the range 4000–50 000 cm−1. The absorption and fluorescence spectra in the 4000–25 000 cm−1 region were not mutually observable in the same host. Interpretations of the spectra are given, based on axial ligand field calculations for a 3d7 configuration including spin-orbit coupling interactions.
