我们用FeCl_3氧化meso-蒽基镍(11)卟啉合成了一种稠合的四蒽基卟啉。该化合物表现出强烈的红移吸收光谱(λ(max)= 1417 nm; λ = 1.2 x 10(5)M-1 cm(-1))和小的电化学HOMO-LUMO带隙(0.61 eV)。晶体结构显示其形成具有短Ni中心点中心点Ni距离(3.32埃)的π堆叠二聚体。
We have synthesized a fused tetraanthracenylporphyrin by oxidation of a meso-anthracenyl nickel(11) porphyrin with FeCl3. This compound exhibits an intense red-shifted absorption spectrum (lambda(max) = 1417 nm; epsilon = 1.2 x 10(5) M-1 cm(-1)) and a small electrochemical HOMO-LUMO gap (0.61 eV). The crystal structure shows that it forms pi-stacked dimers with a short Ni center dot center dot center dot Ni distance (3.32 angstrom).
