  得益于强大的电子耦合，新型双支化有机化合物具有增强的双光子吸收能力

  摘要：

  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。

  coordination-driven self-assembly approach was used to synthesize the first examples of neutral bridging phosphine oxide donor-based supramolecular coordination complexes. The complexes were self-assembled from a fac-Re(CO)3 acceptor, an anionic bridging O donor, and a neutral soft phosphine or hard phosphine oxide donor.

• Synthesis and efficient three-photon excited green fluorescence of pyridine–triphenylamine conjugated dyes

  Pyridine-end-capped triphenylamine derivatives (Py-2-TPA)(n) (n = 1,2,4) were synthesized using palladium-catalyzed Heck reaction and characterized by H-1 NMR, C-13 NMR, and HRMS-MALDI-TOF. Three-photon absorption and three-photon excited fluorescence properties of chromophores (Py-2-TPA)(n) were studied using a femtosecond Ti:Sapphire laser system. These chromophores exhibit efficient three-photon excited green fluorescence peaking at 540-590 nm. The three-photon absorption cros-ssection of sigma(3) = 6.99 x 10(-79) cm(6) s(2) photon(-2) in the femtosecond regime has been obtained from (Py-2-TPA)(4). The ratio of 3PA cross-sections in CH2Cl2 solution sigma(3) (Py-2-TPA)(4):sigma(3) (Py-2-TPA)(2):sigma(3) (Py-2-TPA)(1) is 6.0:4.2:1. The ratio of conjugated Tr-electron numbers in (Py-2-TPA)(n) is 4.4(n = 4):2.6(n = 2):1(n = 1). The increasing the push-pull units of (Py-2-TPA)(n) and pi-electron conjugation length or increasing the extent of charge transfer from the ends to the middle aryl core results in an increase of the 3PA cross-section. The results indicate that large aromatic conjugated chromophores (Py-2-TPA)(n) containing pyridine-tri-phenylamine D-A pairs and a conjugated aryl core provide a new opportunity for 3PA-materials and three-photon fluorophores for practical application.
