The performance of dyes containing carboxylated 1,3-indandiones as electron acceptors was examined. The compounds that included a monocarboxylic group on the 1,3-indandione moiety showed good overall power conversion efficiencies (ca. 2.38%), the values of which were comparable to those of cyanoacrylate derivatives with the same donor–π-linker structure.
Thiophene-based pyridine derivatives: synthesis, crystal structures, two-photon absorption properties and bio-imaging applications in the near-IR region
Two novel D–π–A structural thiophene-based pyridine (N^N^N or N^N^C) chromophores have been designed and synthesized. Then they were characterized by 1H NMR, 13C NMR, IR, MALDI-TOF-MS and single crystal X-ray diffraction analyses. Photophysical properties including UV-vis absorption, fluorescence, and two-photon absorption (2PA) spectra were systematically investigated using both theoretical and experimental
已经设计并合成了两种新颖的D–π–A结构基于噻吩的吡啶(N ^ N ^ N或N ^ N ^ C)发色团。然后用1 H NMR,13C NMR,IR,MALDI-TOF-MS和单晶X射线衍射分析。使用理论和实验方法,系统地研究了包括UV-vis吸收,荧光和双光子吸收(2PA)光谱在内的光物理性质。结果表明,基于噻吩的发色团在近红外区域显示出高荧光量子产率和较大的2PA活性截面。由于其出色的2PA特性,低毒性和低分子量,HepG2细胞的双光子荧光显微镜(2PFM)图像被捕获,表明它们在生物学研究中的潜在应用。
