Laser flash photolysis was used to measure rates of triplet energy transfer from carbazole (Cz) to naphthalene (Np) in rigid solutions of Cz-(CH2)n-Np, where n=4, 5, 6 or 8.The results are interpreted in terms of Dexter's equation and a model which allows for a distribution of donor-acceptor distances for a given n.The distribution was calculated using an arithmetic mean of a center-to-center and closest edge distance between the donor and acceptor chromophores.This model provided the transfer rate for all the compounds tested, and the results indicated a through-space mechanism.
