What is Fluorescence study of some deformed zinc (II) porphyrins about?
The effect of deformation in the porphyrin ring on the emission properties of a series of zinc(II) derivatives of basket handle porphyrins is reported. Emission from the upper excited $2 state is observed in all zinc(II) deformed porphyrins. The porphyrin ring deformation results in red shifts of both the Sl and $2 emission bands and perturbed lifetimes of the St state. Decreased quantum yields and increased intersystem crossing rates are also caused by porphyrin ring deformation. The decrease in the St fluorescence yields can be interpreted in terms of an enhancement of the non-radiative rate, whereas a reduction in the energy gap between the $2 and St states results in low $2 quantum yields relative to planar derivatives.
