The photophysical properties of a series of directly meso,meso-linked porphyrin arrays (Zn(II) 5,15-di(3,5-di-tert-butylphenyl) porphyrin (Z1), its dimer (Z2), trimer (Z3), and tetramer (Z4), were investigated by using the steady-state and time-resolved fluorescence polarization spectroscopy. While the Soret band of Z1 exhibits the absorption maximum at 415nm, those of Z2, Z3, and Z4 are split into...
