  具有强近红外一光子和二光子吸收能力的N环Per取代的和融合的卟啉二聚体

  摘要：

  沿S 0 –S 1电子跃迁轴将两个N环per萘（NP）单元与稠合的卟啉二聚体融合，产生了新的近红外（NIR）染料1 a / 1 b，具有非常强的吸收性（ε>超过1250 nm的距离为1.3×10 5 M -1  cm -1）。两种化合物均显示出适中的NIR荧光，对于1a和1b，其荧光量子产率分别为4.4×10 -6和6.0×10 -6。NP取代的卟啉二聚体2 a / 2 b 通过受控的氧化偶合和环脱氢也可得到三价铁，它们显示出稠合的卟啉二聚体和NP发色团的叠加吸收。飞秒瞬态吸收测量研究了所有这些化合物的激发态动力学，揭示了卟啉二聚体的行为。这些新的生色团还由于扩展的π共轭，在NIR区域具有良好的非线性光学敏感性，并具有较大的双光子吸收截面。进行了随时间变化的密度泛函理论计算，以帮助我们了解它们的电子结构和吸收光谱。

  Porphyrin-based dyes recently have become good candidates for dye-sensitized solar cells (DSCs). However, the bottleneck is how to further improve their light-harvesting ability. In this work, N-annulated perylene (NP) was used to functionalize the Zn-porphyrin, and four "push-pull"-type NP-substituted and fused porphyrin dyes with intense absorption in the visible and even in the near-infrared (NIR) region were synthesized. Co(II/III)-based DSC device characterizations revealed that dyes WW-5 and WW-6, in which an ethynylene spacer is incorporated between the NP and porphyrin core, showed pantochromatic photon-to-current conversion efficiency action spectra in the visible and NIR region, with a further red-shift of about 90 and 60 nm, respectively, compared to the benchmark molecule YD2-o-C8. As a result, the short-circuit current density was largely increased, and the devices displayed power conversion efficiencies as high as 10.3% and 10.5%, respectively, which is comparable to that of the YD2-o-C8 cell (eta = 10.5%) under the same conditions. On the other hand, the dye WW-3 in which the NP unit is directly attached to the porphyrin core showed a moderate power conversion efficiency (eta = 5.6%) due to the inefficient if-conjugation, and the NP-fused dye WW-4 exhibited even poorer performance due to its low-lying LUMO energy level and nondisjointed HOMO/LUMO profile. Our detailed physical measurements (optical and electrochemical), density functional theory calculations, and photovoltaic characterizations disclosed that the energy level alignment, the molecular orbital profile, and dye aggregation all played very important roles on the interface electron transfer and charge recombination kinetics.
