Scheme of the energy transfer mechanism and emission process. The singlet and triplet values of Hcbtfa have been estimated from those reported for Hbtfa [16, 45]. The singlet and triplet values for 5-chloro-1,10-phenanthroline have been taken from [46]. ISC and ET stand for intersystem crossing and energy transfer, respectively.
