Photocatalytically active, multi-chambered, biomolecule-based microspheres were prepared by hierarchical co-assembly of simple dipeptides and porphyrins. The colloidal microspheres are highly hydrated and consist of a network of J-aggregate nanoscale substructures that serve as light-harvesting antennae with a relatively broad spectral cross-section and considerable photostability. These optical properties can be exploited in photocatalytic reactions involving inorganic or organic species. Taken together, these structural and functional features suggest that soft porous biomolecule-based colloids are a plausible photosynthetic model that could be developed towards demonstrating aspects of primitive abiotic cellularity.
通过简单二肽和卟啉的分级共组装,制备了具有光催化活性的多腔室、基于生物分子的微球。胶体微球高度水合,由 J-聚集纳米级亚结构的网络组成,这些亚结构充当光收集天线,具有相对较宽的光谱截面和相当大的光稳定性。这些光学性质可用于涉及无机或有机物种的光催化反应。总之,这些结构和功能特性表明,软多孔生物分子胶体是一种合理的光合作用模型,可以朝着展示原始非生物细胞性的某些方面进行开发。
