title: Synthesis and crystal structure of 2,3,12,13-tetraalkoxy-21, 23-dithiaporphyrins.
abstract: 21,23-Dithiaporphyrins with methoxy, butoxy, octyloxy and dodecyloxy substituents at beta-thiophene carbons were synthesised for the first time and the crystal structure of the butoxy derivative indicated that the substituents at the beta-thiophene carbons induce more planarity in the porphyrin ring.
