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

Investigation of the solubility behavior of para‐substituted (H, Me, t‐Bu, n‐Bu) meso‐tetraarylporphyrins as well as meso‐tetraalkylporphyrins (Me, n‐Pr, n‐Bu) were performed. An increase of solubility in chloroform and benzene is detected according to the higher functionality in para position of the phenyl ring for meso‐tetraarylporphyrins or in meso position on meso‐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.
