In this article, the crystal structure of 5,10,15,20-tetrakis(3′-thienyl)porphinato zinc(II) was examined by steady-state fluorescence measurements.Abstract:
meso-Tetra (2′- and 3′-thienyl)porphyrins and their Zn(II)-complexes were examined by steady-state fluorescence measurements. These molecules exhibit significant bathochromic shift in their emission bands with decreased quantum yields relative to their correspondingmeso-tetraphenylporphyrin derivatives. The crystal structure of 5,10,15,20-tetrakis(3′-thienyl)porphinato zinc(II) shows planar and nonplanar stereochemical features of the macrocycle. One of the macrocycle shows nearly planar while the other exhibited predominantly saddle-shaped geometry. The extent of displacement of the Β-pyrrole carbons in the nonplanar (saddle) conformation is as high as ± 0·422 A.read more

Photophysical and electrochemical properties of meso-substituted thien-2-yl Zn(II) porphyrins.
TL;DR: A detailed analysis of ground and excited state UV-vis absorption, steady-state and time-resolved fluorescence, laser flash photolysis, and electrochemical data all point toward substantial electronic communication between the central Zn(II) porphyrin ring and the meso-thien-2-yl substituents, which is evident from excited state charge transfer character.

Influence of charge and metal coordination of meso-substituted porphyrins on bacterial photoinactivation.
TL;DR: It is demonstrated that the production of ROS and structural deformations due to peripheral substituents and metal coordination, influence the activity of the complexes studied, and is important to perform comprehensive study physics and structurally when predicting or explain such activity.
