pH-tunable phosphorescence and light harvesting in cucurbit[8]uril host–guest assemblies†
Abstract
Host–guest assemblies of halo-phenyl pyridine derivatives and cucurbit[8]uril (CB[8]) exhibited pH-responsive room temperature phosphorescence (RTP) in aqueous media. Moreover, they acted as efficient light-harvesting systems demonstrating triplet–singlet energy transfer to various acceptor dyes.
