The formation of electrostatically linked mixed pentamers of porphyrins and porphyrazines is reported. The photophysical properties of two mixed complexes of well-defined stoichiometry are investigated, using femtosecond laser spectroscopy coupled with pump-and-probe technique and steady-state irrad
## Abstract A simple method has been used to synthesize four porphyrin azides with cores such as N~4~, N~3~S, N~2~SO and N~2~S~2~ in 60–90 % yields by treating the corresponding aminoporphyrins with __tert__‐butyl nitrite (__t__BuONO) and azidotrimethylsilane (TMSN~3~) in THF/CH~3~CN under mild rea
In the pursuit of a porphyrin-fullerene linked hybrid with increased soiubUity and superior cation complexation abilities, hybrid 1 was synthesized. The amphiphilic hybrid 1 was found to be slightly soluble in DMSO, displayed a lower affinity for metal cations than expected, and had a surprisingly h
