Distortions and Deformations of Metaled Meso-Substituted and Unsubstituted Porphyrins and Derivatives in Crystal Structures

Abstract

How to cite this paper: Tsalu, P.V., et al. (2016) In the meso-substituted case, the external and internal twists C β -C α -C meso -X and N-C α -Cmeso-X, re-P. V. Tsalu et al. 2 spectively are oppositely orientated. Similar effect is observed in meso-unsubstituted of C β -C α -C meso -H and N-C α -C meso -H. However, the external distortions are more significant than internal. Considering the same order, the limit of distortions is [97˚ and 132˚ (−48˚)] for external and [91˚ (−89˚) and 52˚] for internal. In the two cases, the substituents have opposite directions of distortions. The meso-substituted porphyrins have a high limit of twisting than usubstituted one, depending of the weight of substituents. The average of the bond angular deformations is 168˚, almost planar. However, the limit of angular deformation is 94˚.

Interaction of Iron(III)-5,10,15,20-Tetrakis (4-Sulfonatophenyl) Porphyrin with Chloroquine, Quinine and Quinidine

“…Porphyrins and their derivatives are well-investigated molecules because of numerous potential applications from molecular electronics, over sensors and information storage elements, to medical agents [1] [2]. Ferric porphyrins seem to play an important role as receptor of an enormous number of ligands [3] [4] [5] [6] [7].…”
