Subporphyrin
Web1 Feb 2008 · A series of novel dendritic carbazole‐functionalized subporphyrins, T(Cz‐Gn)SubPs (n = 1–3), have been synthesized from pyridine–tri(pyrrol‐1‐yl)borane and the corresponding aldehydes. This study has demonstrated that intramolecular energy transfer from the carbazole dendron to the subporphyrin core occurs with a high … Numerous synthetic chlorins with different functional groups and/or ring modifications have been examined. Contracted chlorins can be synthesised by reduction of B(III)subporphyrin or by oxidation of corresponding B(III)subbacteriochlorin. The B(III)subchlorins were directly synthesized as meso-ester B(III)subchlorin from meso-diester tripyrromethane, these class of compound showed ver…
