摘要

The tetraalkoxy and dialkoxy substituted 21, 23-dithiaporphyrins and 21- monothiaporphyrins, respectively, having methoxy, butoxy, octyloxy and dodecyloxy substituents at β-thiophene carbons were synthesized and characterized. The X-ray structure was solved for tetrabutoxy substituted 21, 23-dithiaporphyrin and it exhibited a more planar structure compared with unsubstituted S2TPP, whereas the dimethoxy ...
