合理设计近红外（NIR）吸收分子是开发光功能材料的关键。在这里，我们合成了双核和单核Re（I）三羰基酞菁配合物，在近红外区域表现出尖锐的强Q带。缺电子金属单元的不对称配位同时产生了Q带的显著红移，提高了酞菁环对氧化的耐受性。本研究提出了一种简单而有效的策略，用于构建具有高稳定性的近红外吸收体。
Rational design of near-infrared (NIR) absorbing molecules is crucial for developing photofunctional materials. Here, we synthesized dinuclear and mononuclear Re(I) tricarbonyl phthalocyanine complexes that exhibit a sharp intense Q band in the NIR region. The unsymmetric coordination of electron-deficient metal unit(s) concomitantly produced a remarkable red shift of the Q band and improved the tolerance of the phthalocyanine ring to oxidation. This study presents a simple and effective strategy for the construction of NIR absorbers with high stability.
