摘要：Two new multibranched thiophene-based triarylamine derivatives with 1,3,5-triazine core are synthesized and characterized.Their one-and two-photon absorption properties and aggregation-induced emission effect have been investigated.Both the STAPA-based compounds are AIE active.The two-photon absorption(2PA)cross sections measured by the open aperture Z-scan technique are determined to be 620 and 1610 GM for STAPA-a and STAPA-b in chloroform,respectively,which dramatically increase with the introduction of alkyl chains.The relationship between their structures and properties on one-and two-photon absorption and aggregation-induced emission is discussed,which allows us to examine the effect of introducing alkyl chains.In addition,solvent effects also show a significant influence on the 2PA cross section.The two compounds with excellent AIE and 2PA properties provide attractive alternatives for the biophotonic materials.
