Artificial light-harvesting supramolecular polymeric nanoparticles formed by pillar[5]arene-based host-guest interaction

Artificial light-harvesting nanoparticles were prepared from supramolecular polymers comprised of pillar[5]arene with anthracene-derived donors and acceptors through host-guest interactions. The resulting water-dispersible nanoparticles displayed efficient energy transfer and excellent light harvesting ability in part because the steric bulk of pillar[5]arene suppressed the self-quenching of the chromophores. Water-dispersible artificial light-harvesting supramolecular polymeric nanoparticles ( LHSPNPs ) were prepared from bispillar[5]arene ( bisP5A ) and anthracene-derived guest molecules ( GD and GA ).
