摘要:
The synthesis of new triphenylamine-branching chromophores with dibenzofuran-core and dibenzothiophene-core was reported and the molecular two-photon absorption (TPA) enhancement via core effect and generation effect was investigated. Comparatively, the core effect shows more significant contribution to TPA enhancement than the generation effect. This is of greatly valuable since optimizing dendritic core is laborsaving in comparison with synthesizing dendrimers with high generation. (C) 2008 Elsevier B.V. All rights reserved.
