The luminescence properties at room temperature and 77 K of octamethylcorrole are reported for the first time, together with the photophysical behaviour of corrole-corrole and porphyrin-corrole dyads covalently linked through the 10-position with a phenyl bridge. The photophysical properties of corrole free base are very similar to those of the porphyrin analogues, whereas the dimeric systems show luminescence bands different from those of the parent monomers, indicating an unexpectedly high degree of interaction between the chromophores. The porphyrin-corrole dyad undergoes photocatalysed ring opening of the corrole moiety to give the corresponding porphyrin-biliverdin species.

Members of a new family of lanthanide complexes of the cone-shaped podand 1 and the barrel-shaped cryptand 2, based on calix[4]arenes incorporating bipyridine N,N′-dioxide chromophores, have been synthesized and characterized. The complexes were found to be stable in water and coordinating solvents. High molar absorption coefficients {ϵ = 28000 and 36000 M−1cm−1 for [Eu(1)]3+ and [Eu(2)]3+, respectively} and high metal luminescence quantum yields {Φ = 0.19 and 0.11 for [Eu(1)]3+ and [Eu(2)]3+, respectively} were obtained. The effect of OH oscillators, attached at the lower rim of the calixarenes, on the non-radiative deactivation to the ground state has been demonstrated.
