A series of dipolar-type terphenyl derivatives 13 featuring an electron donor (p-NMe2C6H4 group) and acceptor (p-NO2C6H4 group) unit was synthesized and their photophysical properties were investigated. By using aromatic heterocycles (thiophene, furan, pyrrole) as the π-linkers between the donor and acceptor units, significant effects on the bathochromic shift and enhancement of the two-photon absorption wavelength and the two-photon absorption cross-sections were observed, respectively.

五元杂环对包括双光子吸收特性在内的光物理性质的影响

一系列偶极型三联苯衍生物的1 - 3设有一个电子给体(p -NMe 2 ç 6 ħ 4基团)和受体(p -NO 2 ç 6 ħ 4组)单元合成和它们的光物理性质进行了研究。通过使用芳香杂环(噻吩、呋喃、吡咯)作为供体和受体单元之间的π-连接体,观察到对红移和双光子吸收波长和双光子吸收截面增强的显着影响,分别。
