以多环芳烃二噻吩并[2′，3 ′：2，3;3′′，2 ′′：10，11]二噻吩并[1，14，13，12-bcdefgh]咔唑（DTPC）为主要骨架，并修饰有多个增溶基团的电子给体与4-（苯并[c][1，2，5]噻二唑-4-基乙炔基）苯甲酸偶联，用于无金属有机染料（C281）。该近红外光敏染料在480 nm至735 nm的宽光谱范围内表现出超过80%的外量子效率，并且在模拟AM 1.5G太阳光（100 mW cm-2）的辐照下表现出13.0%的高功率转换效率。
An electron-donor with a polycyclic aromatic hydrocarbon dithieno[2′,3′:2,3;3′′,2′′:10,11]piceno[1,14,13,12-bcdefgh]carbazole (DTPC) as the primary skeleton and also decorated with multiple solubilizing groups is coupled to 4-(benzo[c][1,2,5]thiadiazol-4-ylethynyl)benzoic acid, for a metal-free organic dye (C281). The near-infrared photosensitizing dye exhibits over 80% external quantum efficiency in a broad spectral range from 480 nm to 735 nm, and a high power conversion efficiency of 13.0% under irradiance of simulated AM 1.5G sunlight (100 mW cm−2).
