In this study, we designed and constructed two artificial light-harvesting systems based on the supramolecular self-assembly of acylhydrazone functionalized quinoline (L), Al3+, and fluorescent dyes. The L-Al3+ supramolecular assembly significantly improved aggregation-induced emission enhancement and served as a donor for the light-harvesting systems. Acridine yellow and acridine orange were found to be efficient acceptors for the energy transfer process.
We have designed and constructed two artificial light-harvesting systems (ALHSs), which are based on the supramolecular self-assembly of acylhydrazone functionalized quinoline (L), Al3+ and fluorescent dyes. The L-Al3+ supramolecular assembly distinctly improved aggregation-induced emission enhancement and served as a donor for ALHSs. Acridine yellow and acridine orange were found to be good acceptors to realize the energy transfer process with good efficiency.
