✦ Synopsis

The mqncttc field depcndcncc of hetcrofuston between trlplet ewxtons and guest trIplets m a pyrene-dto doped fluorcne smglc crystal has been mvcsttgatcd We found that the gucstdelayed fluorescence mtcnstty mcreascs at low field The delayed fluoresccrcc reaches a mawmum tn the rcgton bctwecn 400 and 600 G and then decreases wth mcreasmg magnetic field strength, reachmg a plateau at high fields The results arc dtscussed m terms of a density-matrtzz descrtptton of the spin states of mtcractmg trlplet pairs The ESR spectra of host-guest trIplet paus have been recorded m the same crystal system
