Abstract: T riplet-triplet energy transfer proceeds via Dext erelec ron exchange interaction[1].The rate constant for such an energy transfer decreases exponentially with increasing thedonor-acceptor distance,and will become negligibly small as the donor-accept or distance increases beyond the sum of their van der Waals radii.

Key words: triplet energy transfer, crown-ether, benzophenone, naphthalene
