Alternating and statistical copolymers of 9-vinylcarbazole with diethyl fumarate (1), diethyl maleate (2), methacrylic acid (3), maleic anhydride (4), or maleic acid (5) were synthesized and characterized. These copolymers were tested as polymer ligands, that might be able to suppress the environmental vibronic quenching of a lanthanide ion and, simultaneously, to function as energy donors in the ligand-to-metal energy transfer processes. Time-resolved luminescence of a series of [Tb(III)-ligand] complexes in common and deuterated solvents revealed that the complexing properties of copolymers 3 or 5 are stronger than those of 1 or 2. Consequently, the strong binding affinity decreases the ligand-metal (donor-acceptor) distance and gives rise to an efficient ligand-to-metal energy transfer. Thus, the intensities of the long-lived emission (5D4→7F6, 5D4→7F5, 5D4→7F4, 5D4→7F3) of the [Tb(III)-3], [Tb(III)-5], and [Tb(III)-1] or [Tb(III)-2] complexes were found to be eight times, five times, and less than twice that of uncomplexed Tb3+, respectively.

Energy transfer from the triplet level of a donor molecule resulting in quenching of the donor and elevation of the acceptor molecule from its singlet ground state to a triplet state has been observed between a number of donor-acceptor pairs in fluid solvents. In most cases the mechanism of the transfer has been unequivocally established by observation of the triplet state absorption spectra of both species. Energy transfer from excited singlet donors to the triplet state of the acceptor is not observed. When the energy of the acceptor triplet is considerably lower than that of the donor, transfer is diffusion-controlled but there is no evidence for long-range resonance transfer of the kind found in the analogous singlet energy transfer processes. As the triplet energies become comparable the transfer probability is reduced and no quenching is observed by molecules with triplet levels higher than that of the donor. Transfer of triplet energy between pairs of aromatic hydrocarbons has been illustrated and it has been established that complex formation between donor and acceptor cannot be important under the conditions of these experiments.
