Advanced Optical Materials, EarlyView.Bis‐naphthyl‐4‐hydroxy‐dipicolinic‐dicarboxamide, a small molecule, forms nanodispersion as an efficient light‐harvesting medium in aqueous solution. Further cucurbit[7]uril addition was found to inhibit the FRET co‐assembly by host‐guest complexation. ABSTRACT Development of artificial light harvesting systems in a minimalistic self‐assembly model is ...
