Metalloisoporphyrinoids have been minimally explored as NIR photothermal materials. metalloisocorrole complexes (Figure ). The isoporphyrinoid macrocycles in these complexes are thought to be antihomoaromatic, and feature strong absorption maxima overlapping the 785nm laser wavelength used in this study. The four metalloisoporphyrinoid materials were synthesized according to previously reported methods. As these materials are not inherently
