A series of dipolar-type terphenyl derivatives 1–3 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。
