donor-pi-donor derivatives containing phenyl, naphthyl, and anthryl groups as the pi-center and heterocyclic rings as the conjugation bridge have been synthesized and their one- and two-photon spectroscopic properties and photostability were determined. These compounds show bathochromic shifts in the absorption and emission spectra, larger two-photon cross-section, and enhanced photostability in comparison to
合成了一系列含有苯基,萘基和蒽基作为pi-中心和杂环作为共轭桥的供体-pi-供体衍生物,并确定了它们的单光子和双光子光谱性质和光稳定性。与它们的开链类似物相比,这些化合物在吸收和发射光谱中呈现出红移,具有更大的两光子截面,并具有更高的光稳定性。此外,提出了一种方便的定性光稳定性测量方法。
