4-tert-Butylphenyl-substituted and fused quinoidal porphyrins 1 and 2 are prepared for the first time. They show (1) intense one-photon absorption in the far-red/near-infrared region, (2) enhanced two-photon absorption compared with aromatic porphyrin monomers, and (3) amphoteric redox behavior. Their geometry and electronic structure are studied by DFT calculations.
4-叔丁基取代并稠合的醌式卟啉 1 和 2 是首次制备的。它们表现出(1)在远红光/近红外区域的强单光子吸收,(2)与芳香卟啉单体相比增强的双光子吸收,和(3)两性氧化还原行为。通过 DFT 计算研究了它们的几何形状和电子结构。
