Solvent effects on the photochemical and fluorescence properties of zinc phthalocyanine derivatives
A Ogunsipe, D Maree, T Nyokong - Journal of Molecular Structure, 2003 - Elsevier
The effects of solvents on the singlet oxygen, photobleaching and fluorescence quantum
yields for zinc phthalocyanine (ZnPc) and its derivatives;(pyridino) zinc phthalocyanine ((py)
ZnPc), zinc octaphenoxyphthalocyanine (ZnOPPc) and zinc octaestronephthalocyanine
(ZnOEPc), is presented. The effects of the solvents on the ground state spectra are also
discussed. The largest red shift of the Q band was observed in aromatic solvents, the highest
shift being observed for 1-chloronaphthalene. Higher singlet fluorescence quantum yields …
