An expanded metalloporphyrin-based "black dye" Au-Pd oxohexaphyrin (AuPd-1) with absorption capabilities across the visible-to-near-infrared (NIR) range was synthesized. This black dye, AuPd-1, possessed efficient light-harvesting and photostable capabilities, which were indicative of superior photothermal (PT) conversion abilities. Encapsulation of AuPd-1 with a micellar nanocapsule resulted in a compound that demonstrated intense photoacoustic (PA) properties in the NIR region in water. This finding indicated how metal (d)-ligand (π) molecular orbital interactions in metalloporphyrins could aid in the design of visible-to-NIR light-harvesting black dyes for PT and PA applications.

具有跨可见光到近红外区域吸收能力的黑色染料的合成：通过扩展卟啉的杂金属配位的 MO 混合方法

合成了一种扩展的基于金属卟啉的“黑色染料”Au-Pd oxohexaphyrin (AuPd-1)，其在可见光到近红外 (NIR) 范围内具有吸收能力。这种黑色染料 AuPd-1 具有高效的捕光和光稳定能力，这表明其具有卓越的光热 (PT) 转换能力。用胶束纳米胶囊封装 AuPd-1 产生的化合物在水中的 NIR 区域表现出强烈的光声 (PA) 特性。这一发现表明金属卟啉中的金属 (d)-配体 (π) 分子轨道相互作用如何有助于设计用于 PT 和 PA 应用的可见光至近红外光捕获黑色染料。
