Synthesis of functionalized thia analogues of phlorins and covalently linked phlorin–porphyrin dyads†
Abstract
The 21,23-dithia and 21-thia analogues of phlorins and mono-functionalized thiaphlorins were synthesized using easily available precursors and the mono-functionalized thiaphlorins were used further to synthesize the first examples of three covalently linked thiaphlorin–porphyrin dyads.
