  摘要：

  合成了一类接受体-酮-供体结构，包括受阻的9,9-二（3,5,5-三甲基己基）-2-二苯胺氟烯-美琅[60]富勒烯C60(>DPAF-C9)及相关的双加合物C60(>DPAF-C9)2和C60(>DPAF-C2)2。它们是多光子吸收C60(>DPAF-C2)的衍生物，在激光激发下800 nm的纳秒区域显示出增强的同时两光子吸收截面。这些C60-DPAF共轭物的分子合成涉及通过酮联结将二苯氨基氟烯部分共价连接到美琅[60]富勒烯上，以增加分子的接受体-供体极性，与富勒烯笼体结合。7-(1,2-二氢-1,2-美琅富勒烯[60]-61-羰基)-9,9-二烷基-2-二苯胺氟烯C60(>DPAF-Cn)的制备涉及用关键合成单元7-α-溴乙酰-9,9-二烷基-2-二苯胺氟烯对C60进行环丙烷化。该合成单元的合成通过三步法实现，起始于2-溴氟烯，通过对氟烯环的C9位的双烷基化，在双烷基氟烯的C2位上连接二苯胺基团，以及在二苯胺氟烯的C7位对α-溴乙酰基进行弗riedel-Craft酰化。所有C60-DPAF衍生物均经过全面表征，化学结构通过各种光谱分析确认，并通过C60(>DPAF-C2)的单晶结构分析数据进行验证。观察到C60(>DPAF-C2)、C60(>DPAF-C9)和C60(>DPAF-C9)2的强溶剂敏感荧光猝灭现象，在更极性溶剂（如DMF、PhCN和THF）中未观察到700 nm以上的荧光带，而在较少极性的溶剂（如甲苯、CHCl3和CS2）中观察到700-710 nm的富勒烯荧光带。这归因于在前一组溶剂中，通过富勒烯部分的单态激发态1C60*(>DPAF-Cn)发生电子转移。相反，在后者溶剂组中，DPAF-Cn部分向富勒烯笼体的能量转移过程更加有利。

• 2,7-Diaminofluorene-Based Organic Dyes for Dye-Sensitized Solar Cells: Effect of Auxiliary Donor on Optical and Electrochemical Properties

  New organic dyes containing a diarylaminofluorene unit as an electron donor and cyanoacrylic acid as acceptor and anchoring group in a donor-pi-donor-pi-acceptor architecture have been synthesized and characterized as sensitizers for nanocrystalline TiO2-based dye-sensitized solar cells. They have shown three major electronic absorptions originating from the pi-pi* and charge-transfer transitions covering the broad visible range (250-550 nm) in solution. The charge-transfer transition of the dyes exhibited negative solvatochromism, suggesting a polarized ground state. They have also displayed acidochromism in solution owing to the presence of a protonation-deprotonation equilibrium. On comparison with the triphenylamine and carbazole-based parent dyes (E)-2-cyano-3-(4-(diphenylamino)phenyl)acrylic acid and (E)-2-cyano-3-(9-ethyl-9H-carbazol-3-yl)acrylic acid they exhibited longer wavelength absorptions and facile oxidation, indicating the stronger electron-donating ability of the auxiliary chromophores. In addition, they exhibited nearly two times larger light-to-electron conversion efficiency under simulated AM 1.5 G irradiation (100 mW cm(-2)) with an aperture mask when compared to the parent dyes. Among the new dyes, the one containing the naphthylphenylamine segment showed better device characteristics attributable to the higher HOMO energy level which probably facilitates the regeneration of the dye and effective suppression of the back reaction of the injected electrons with the I-3(-) in the electrolyte. The optical properties of the dyes were modeled using TDDFT simulations employing different theoretical models (B3LYP, CAM-B3LYP, and MPW1K), and the best correlations with the observed parameters have been found for CAM-B3LYP and MPW1K calculations. The electron lifetimes extracted from the electrochemical impedance measurements of the dye-sensitized solar cells were used to interpret the solar cell efficiency alternations.
