摘要
An intramolecular excimer of poly（2- vinyl） naphthalene was formed by non-adjacentchromophores interaction, then a triple exciplex was formed by interaction with the acceptormolecule further in dilute solution. The lifetime of the intramolecular excimer of poly（2-vinyl） naphthalene, τ<sub>2</sub> = 18.83 ns and the rate constant for the triple exciplex formation,k<sub>7</sub> = 4. 18× 10<sup>9</sup> （mol/L）<sup>-1</sup>s<sup>-1</sup>, under diffusion-control were measured. An excimer or anexciplex could be an intermediate of the triple exciplex formation. A theoretical model ofthe triple exciplex formation is proposed.
An intramolecular excimer of poly(2- vinyl) naphthalene was formed by non-adjacent
chromophores interaction, then a triple exciplex was formed by interaction with the acceptor
molecule further in dilute solution. The lifetime of the intramolecular excimer of poly(2-
vinyl) naphthalene, τ_2 = 18.83 ns and the rate constant for the triple exciplex formation,
k_7 = 4. 18× 10~9 (mol/L)^(-1)s^(-1), under diffusion-control were measured. An excimer or an
exciplex could be an intermediate of the triple exciplex formation. A theoretical model of
the triple exciplex formation is proposed.
