The α(4) atropoisomer of a tetraaryl porphyrin and its Pd(II) complex, both bearing four hydroxyquinolinyl chelating units pre-organised on the same face of the porphyrin backbone, bind a Nd(III) centre thus affording either a mononuclear or a heterobinuclear anionic species, respectively. The near-infrared emission of the lanthanide centred at 1064 nm is observed upon excitation of the Soret band at 425 nm. Sensitisation proceeds mainly from the singlet state of the porphyrin.
一种四芳基卟啉的 α(4) 对映异构体及其 Pd(II) 配合物，都在卟啉主链的同一面上承载四个羟基喹啉螯合单元，结合一个 Nd(III) 中心，从而分别提供单核或异双核阴离子物种。在 425nm 处激发 Soret 带时，可以观察到以镧系元素为中心的近红外发射，位于 1064nm 处。敏化主要来自卟啉的单重态。
