Sensitisation of the near-infrared emission of Nd(III) from the singlet state of porphyrins bearing four 8-hydroxyquinolinylamide chelates.
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.
