合成并表征了一类新型的具有酸构型的双氮杂二氧六卟啉（c-ZnCu-2和c-CuZn-2）的异源铜（II）/锌（II）配合物.所得到的杂金属配合物具有独特的近红外（NIR）吸收特征，而其易于氧化还原的活性来源于其26位共轭的大结构。c-ZnCu-2和c-CuZn-2的电子顺磁共振谱中d9铜中心的特定结构参数和碱滴定时锌中心的刘易斯酸性存在明显的位置依赖性差异。这些配合物具有响应近红外光的含异质金属材料应用的潜力。
Novel site-selective hetero-copper(II)/zinc(II) complexes of acisoid-configured doubly N-confused dioxohexaphyrin analog (c-ZnCu-2andc-CuZn-2) were synthesized and characterized. The resulting heterometal complexes exhibited a unique near-infrared (NIR) absorption feature, and the facile redox-active properties originated from the large 26-conjugated structure. The distinct difference between the site-dependentc-ZnCu-2andc-CuZn-2appeared in the specific structural parameters of the d9copper centers in the electron paramagnetic resonance spectra and the Lewis acidity of the zinc centers upon the base-titrations. These complexes have potential for the hetero-metal-containing-material applications that respond to the NIR light.
