Abstract
We have synthesized a fused tetraanthracenylporphyrin by oxidation of a meso-anthracenyl nickel(II) porphyrin with FeCl(3). This compound exhibits an intense red-shifted absorption spectrum (λ(max) = 1417 nm; ε = 1.2 × 10(5) M(-1) cm(-1)) and a small electrochemical HOMO-LUMO gap (0.61 eV). The crystal structure shows that it forms π-stacked dimers with a short Ni···Ni distance (3.32 Å).
摘要
我们通过用三氯化铁氧化间-蒽基镍(II)卟啉合成了一个稠合四蒽基卟啉。该化合物表现出强烈的红移吸收光谱（λ(max) = 1417nm；ε = 1.2×10(5)M(-1)cm(-1)）和较小的电化学 HOMO-LUMO 能隙（0.61eV）。晶体结构表明，它形成了π-堆积二聚体，Ni···Ni 距离较短（3.32Å）。
