An expanded metalloporphyrin-based "black dye" Au-Pd oxohexaphyrin () with absorption capabilities across the visible-to-near-infrared (NIR) range was synthesized. This black dye, , possessed efficient light-harvesting and photostable capabilities, which were indicative of superior photothermal (PT) conversion abilities. Encapsulation of 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.
一种基于扩展金属卟啉的“黑染料”Au-Pd 氧六叶啉（）具有可见到近红外（NIR）范围内的吸收能力。这种黑染料，具有高效的光捕获和光稳定性能力，表明其具有优越的光热（PT）转换能力。用胶束纳米胶囊封装后，得到了一种在水中具有强烈近红外光声（PA）特性的化合物。这一发现表明金属（d）-配体（π）分子轨道相互作用如何有助于设计用于 PT 和 PA 应用的可见到近红外光捕获黑染料。
