Paper Abstract

The present work is aimed at investigating the triplet- triplet excitation energy transfer process between dyes and polycyclic aromatic hydrocarbons in microheterogeneous micellar solutions of sodium dodecylsulphate. The result of the transfer is the sensitized room-temperature phosphorescence of polycyclic aromatic hydrocarbons observed for the first time. Spectral and photophysical properties of donor and acceptor solubilized in the micelles were studied, constants characterizing the `heavy atom' effect on the singlet and triplet states of the lumiphor were determined. The constant of the triplet energy transfer between triphaflavine (donor) and pyrene (acceptor) was obtained.
