Synthesis and Photophysical Properties of Porphyrins with Fluorenyl Pendant Arms
Résumé
Symmetrical-A 4-porphyrins bearing four fluorene donor moieties TOFP (5,10,15,20-tetra(4-(2 methyloxyfluorenyl)phenyl)porphyrin as well as eight fluorene arms OOFP (5,10,15,20-octa(3,5-(2 methyloxyfluorenyl)phenyl)porphyrin, were synthesized and characterized. Preliminary photophysical properties are reported. In comparison to the reference tetraphenylporphyrin TPP, the luminescence properties are slightly improved. The fluorescence quantum yields of tetrafluorenylporphyrin TOFP (1) and octafluorenylporphyrin OOFP (2) are 0.10 and 0.13, respectively.
