摘要：

This study reports the synthesis and the two-photon absorption (TPA) properties of a series of 9,10-anthracene-centred oligo(p-phenyleneethynylene)s with end-capping didecylamine. The results show that both the maximal TPA cross-sections (delta(max)) and the fluorescence quantum yields (Phi) of the oligomers increase with the extension of phenylethynyl bridges. Interestingly, the Phi delta(max) per repeating unit to is obviously enhanced by extending linearly conjugation size of the oligomers. Moreover, these oligomers all show the maximal two-photon absorption cross-sections at 800 run and emit strong green to yellowish-green two-photon excited fluorescence. These materials may find applications in which two-photon excited fluorescence and photo-induced electron transfer are utilized. Crown Copyright (C) 2009 Published by Elsevier B.V.
