Bis(chlorido)tin(IV)meso‐substituted Porphyrins‐Characterization and Solubility

Abstract

Investigation of the solubility behavior ofpara‐substituted (H, Me,t‐Bu,n‐Bu)meso‐tetraarylporphyrins as well asmeso‐tetraalkylporphyrins (Me,n‐Pr,n‐Bu) were performed. An increase of solubility in chloroform and benzene is detected according to the higher functionality inparaposition of the phenyl ring formeso‐tetraarylporphyrins or inmesoposition onmeso‐tetraalkylporphyrins. Furthermore, the series of bis(chlorido)tin(IV)meso‐tetraarylporphyrin and bis(chlorido)tin(IV)meso‐tetraalkylporphyrin was investigated via UV/Vis spectroscopy,¹¹⁹Sn‐NMR and single crystal X‐ray diffraction.
