Optical spectra of CoBr42- in molten tetrabutylphosphonium bromide are recorded and the bands interpreted as due to charge-transfer and ligand-field transitions. The resolved spin-allowed bands are similar to those reported earlier in organic solvents. Cobalt(II)-bromide-rich mixtures with tetrabutylphosphonium bromide are found to supercool to a glassy material. The effect of temperature on these bands has also been studied.

Polarized Luminescence

The host-guest binding between a chiral macrocycle and an achiral dye could suppress the twisted intramolecular charge transfer (TICT) process, leading to enhanced emission and bright circularly polarized luminescence from...
