摘要：

Electrongenerated chemiluminescence ( ECL) of a series of intramolecular charge transfer ( ICT) donor - acceptor stilbenoid systems ( 2 - 9) bearing N, N- dimethylamino group as donor and pyridine, thiophene, quinoline or aryl groups as acceptors are studied. Most of the compounds ( 3 - 9) show ICT ECL through direct annihilation of the radical ions. For the weaker ICT compound ( 2), excimer ECL is observed instead.
