以卟啉为掺杂剂，通过芳香肽的自组装制备了集光杂化水凝胶，实现了太阳能-电子能的有效转换。芳香肽的长程有序组装可以作为光电子受体和导体，促进光天线卟啉分子产生光电子。同时，卟啉的掺杂可以有效降低肽基水凝胶的电阻，促进光电子的传递。光电流测试结果表明卟啉/肽水凝胶具有良好的光响应特性，光电子产率高达672 nA cm（-2），具有很好的太阳能转化潜力。
Light-harvesting hybrid hydrogel was fabricated based on self-assembly of an aromatic peptide with porphyrin as a dopant for an effective solar-electronic energy conversion. The long-range order assembly of aromatic peptide can act as photoelectron acceptor and conductor to promote the production of photoelectrons by the light antenna porphyrin molecules. In the meanwhile, the doping of porphyrin can effectively reduce the resistance of peptide-based hydrogel, facilitating the transfer of photoelectrons. Photocurrent test result demonstrates the great light response property of the porphyrin/peptide hydrogel with a photoelectron yield as high as 672 nA cm(-2), which holds great potential for enhanced solar energy conversion.
