Abstract
A supramolecular assembly was constructed by the nonconvalent interaction of pillar[5]arene (WP5) with a pyridinium modified tetraphenylethene (Py-TPE) derivative, in which Py-TPE/WP5 acted as a donor, and sulforhodamine 101 and sulfonated aluminum phthalocyanine acted as acceptors to realize a highly efficient light-harvesting system with two-step sequential energy transfer.
