Don't hesitate, metalate! Palladium complexes of carbazole-based isophlorins (see figure) were synthesized. Metalation planarized the structures and generated antiaromatic character. The complexes showed weak near-infrared (NIR) absorption in solution. In addition, the sulfur- and selenium-based complexes formed trimeric and dimeric stacked layered structures, respectively, and showed relatively strong NIR absorption in the solid state.

咔唑基硫属元素鬼臼毒素的钯配合物：合成，结构和固态近红外吸收光谱。

不要犹豫，金属化！合成了咔唑基异佛尔林的钯配合物（见图）。金属化使结构平面化并产生抗芳烃特性。络合物在溶液中显示弱的近红外（NIR）吸收。另外，基于硫和硒的络合物分别形成三聚体和二聚体堆叠的层状结构，并且在固态下显示出相对较强的NIR吸收。
