Abstract

Inner-and peripheral-metal complexation behaviors of 5,10,15-tris(pentafluorophenyl)-20-pyrrolyl N-confused porphyrin (5) and its meso-pyrrolyl-bridged dimers (6-Ni and 7-Ni) were studied in this work. The resulting inner-Ag and peripheral-BF2 complex (5-AgBF2) exhibited the bathochromically shifted absorption feature (72 nm), which was attributed to the BF2 complexation. Furthermore, the bis-Ag/Ni complexes of dimer (6-Ag2Ni and 7-Ag2Ni) revealed remarkably lower energy bands in the deeper near-infrared (i.e. NIR-II) region (λmax = 1226 and 1042 nm, respectively) through strong interchromophore interactions.
