主 题:Light harvesting system Supramolecular polymer Quadruple hydrogen bonding AIE Self-assembly
摘 要:Stepwise energy transfer is ubiquitous in natural photosynthesis,which greatly promotes the widespread use of solar ***,we constructed a supramolecular light harvesting system based on sequential energy transfer through the hierarchical self-assembly of M,which contains a cyanostilbene core flanked by two ureidopyrimidinone motifs,endowing itself with both aggregation-induced emission behavior and quadruple hydrogen bonding *** monomer M can self-assemble into hydrogen bonded polymers and then form supramolecular polymeric nanoparticles in water through a mini-emulsion *** nanoparticles were further utilized to encapsulate the relay acceptor ESY and the final acceptor NDI to form a two-step FRET *** fluorescence including a white-light emission was successfully *** work not only shows a desirable way for the fabrication of efficient two-step light harvesting systems,but also shows great potential in tunable photoluminescent nanomaterials.
