A series of carotenoporphyrins whose conformations, as determined from 1H NMR studies, range from folded (with the carotenoid ¦Ð-electron system stacked over that of the porphyrin) to extended (with the chromophores widely separated) were prepared Time-resolved spectroscopic studies revealed intramol. triplet energy transfer from porphyrin to carotenoid. Two distinct pathways for such transfer (presumably occurring via an electron-exchange mechanism) were observed: (a) static transfer which does not require significant intramol. motions and (b) dynamic transfer mediated by intramol. motions. The relative importance of these pathways is a function of mol. structure and dynamics. The results for this series of carotenoporphyrins help define the photochem. and photophys. requirements for protection from singlet oxygen damage both in photosynthetic organisms and in other biol. systems. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Recommanded Product: 57412-08-5).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand design occupies a central place in organic synthesis and catalysis. The ligands are electron-rich and highly tunable to provide catalyst systems with a diverse scope, high stability, and reactivity.Recommanded Product: 57412-08-5
