In this paper, a new approach for fabricating donor-acceptor (D-A) arrays, (Si-TCP)_n-PhC₆₀NH₃⁺, 5,10,15,20-Tetrakis(benzo-15-crown-5)porphyrin (TCP), 2-Phenyl-5-(n-butylammonium)-3,4-fulleropyrrolidine (PhC₆₀NH₃⁺), on indium-tin oxide (ITO) electrode is demonstrated. Electronic absorption spectra, atomic force microscopy, infrared spectroscopy, electrochemical impedance spectroscopy, and X-ray diffraction analysis were used as powerful tools to characterize (Si-TCP)_n arrays and (Si-TCP)_n-PhC₆₀NH₃⁺ arrays on the ITO electrode. The (Si-TCP)_n-PhC₆₀NH₃⁺ arrays was immobilized on the electrode avoided the traditional fussy operations for immobilizing both porphyrin materials and fullerene, which led to a significantly reduction of background signal and an enhancement of initial photocurrent signal. These results would provide fundamental clues for the molecular design of high-performance organic photovoltaics.

本文提出了一种新的制备供体-受体（DA）阵列的方法，即（Si-TCP）_n -PhC ₆₀ NH ₃ ⁺，5,10,15,20-四（苯并-15-冠-5）卟啉（在铟锡氧化物（ITO）电极上显示了TCP），2-苯基-5-（正丁基铵）-3,4-全吡咯烷酮（PhC ₆₀ NH ₃ ⁺）。电子吸收光谱，原子力显微镜，红外光谱，电化学阻抗光谱和X射线衍射分析被用作表征（Si-TCP）_n阵列和（Si-TCP）_n -PhC ₆₀ NH ₃ ⁺阵列的有力工具。 ITO电极。（Si-TCP）_n-PhC ₆₀ NH ₃ ⁺阵列固定在电极上，避免了用于固定卟啉材料和富勒烯的传统繁琐操作，从而显着降低了背景信号并增强了初始光电流信号。这些结果将为高性能有机光伏的分子设计提供基础线索。
