Abstract :
Intramolecular electronic energy transfer in methylenes-linked naphthalene and anthracene (referred to as AnN, n=1, 3 and 6 denoting number of methylene units) was examined by time-correlated single-photon counting technique in n-hexane and in stretched PVA films. The energy transfer rates in A1N, A3N and A6N in solution were measured and the chain length dependence of these rate constants is discussed in terms of through-bond interaction via the connecting bridge, in addition to direct Coulombic interaction.
