Zinc azaphthalocyanines with thiophen-2-yl, 5-methylthiophen-2-yl and pyridin-3-yl peripheral substituents: Additive substituent contributions to singlet oxygen production.

Abstrakt

On the series of several zinc azaphthalocyanines we discovered, that singlet oxygen quantum yields of azaphthalocyanines can be easily calculated as a sum of additive contributions of peripheral substituents.
