multi-branched organic compounds, 1,2,4,5-tetrakis[(4′-N,N-diethylamino)styryl]benzene (TDEASB) and 1,2,4,5-tetrakis[(4′-N,N-dibutylamino)styryl]benzene (TDBASB), with strong electronic coupling among the conjugated arms, have been designed and synthesized. Their single-photon and two-photon absorption (TPA) and photoluminescent (PL) properties have been studied carefully. The two-photon absorption cross-sections
两种新型的多支有机化合物,1,2,4,5-四[[4'- N,N-二乙基氨基)苯乙烯基]苯(TDEASB)和1,2,4,5-四[[4'- N,N设计并合成了在共轭臂之间具有强电子偶联的-二丁基氨基)苯乙烯基苯(TDBASB)。已经仔细研究了它们的单光子和双光子吸收(TPA)和光致发光(PL)特性。通过使用200 fs,76 MHz,Ti:蓝宝石激光器的双光子激发荧光技术估算了这两种化合物的双光子吸收截面,对于TDEASB和TDBASB而言,它们分别高达810和1030 GM。TPA横截面很强,表明这些苯核基多支化化合物具有出色的共轭和电子离域性能。
