Porphyrins and their analogues are well-known "pigments of life", which are involved in light-harvesting, oxygen transfer, and transformation of biological substrates. A variety of synthetic porphyrins have been studied as artificial light-harvesting materials with the best system providing >13% efficiency in the solar light-to-electricity conversion. Ferrocene-containing porphyrins, borondipyrromethenes (BODIPYs), and boronazadipyrromethenes (aza-BODIPYs) are prominent candidates for light-harvesting. Efficient use of such compounds in organic photovoltaics (OPV) requires non-covalent attachment of these molecules to the electron-acceptors such as fullerenes, nanotubes, and graphene. The pyrene group can facilitate such desired non-covalent interactions with nanocarbon materials.

卟啉及其类似物是众所周知的“生命色素”，它们参与光捕获、氧转移和生物底物的转化。已经研究了各种合成卟啉作为人工捕光材料，其中最好的系统在太阳能光电转换中提供>13%的效率。含二茂铁的卟啉、硼二吡咯亚甲基（BODIPY）和硼氮二吡咯亚甲基（aza-BODIPY）是用于光捕获的突出候选物。在有机光致发光材料（OPV）中有效使用此类化合物需要将这些分子非共价连接至电子受体，例如富勒烯、纳米管和石墨烯。芘基团可以促进与纳米碳材料的这种期望的非共价相互作用。
