40 000 M−1 cm−1. The light‐to‐electricity conversion efficiencies of the dye‐sensitizedsolarcells (DSSCs) fabricated from the dyes range from 6.11 to 7.59 % under simulated AM 1.5 G illumination. Upon addition of a threefold concentration of chenodeoxycholic acid as the co‐adsorbent, the best performance cell has a power‐conversion efficiency of 8.41 %, which is higher than that of the N719‐based standard DSSC
新型供体-受体'-受体型敏化剂(QBT染料),包括芳基胺作为电子供体,双硫杂[3,2- f:2',3'- h ]喹喔啉作为内部受体,2-氰基丙烯酸为受体和锚均已合成。QBT染料具有宽吸收光谱,涵盖λ = 368–487 nm范围,最大消光系数高达约40 000 M -1 cm -1。在模拟AM 1.5 G照射下,由染料制成的染料敏化太阳能电池(DSSC)的光电转换效率为6.11%至7.59%。加入三倍浓度的鹅去氧胆酸作为辅助吸附剂后,性能最佳的电池的功率转换效率为8.41%,高于基于N719的标准DSSC(8.27%)。

Pyrazino[2,3-g]quinoxaline was first employed as a π-linker in D–π–A type dyes, exhibiting an unusually broad and intense spectral absorption ranged from the visible to the near infrared region.
A series of conjugated polymer-based nanoparticles having far-red/near infrared emission ranges are disclosed. Cross coupling methods to prepare the conjugated polymers and methods of nanoparticle preparation are also discussed. The conjugated polymer nanoparticles are used as FR/NIR fluorescent probes in in vitro and in vivo biosensing and bioimaging applications, and are also used in photoacoustic imaging as contrast agents. Finally, use of the conjugated polymer nanoparticles in photothermal therapy is described.
