Amphiphilic light-emitting dendrons with oligo(phenylene vinylene) branches and oligo(ethylene oxide) terminal chains

We have recently synthesized new amphiphilic light-emitting dendrons with oligo(phenylene vinylene) core–branches and oligo(ethylene oxide) terminal chains (designated as: OPPV-d-OPEO). Due to the amphiphilic properties arising from the large difference in solubility between the two components, unique concentration- and temperature-dependent photoluminescence emissions were observed for aqueous solutions of the amphiphilic conjugated dendrons. The synthesis and amphiphilic behaviour of the OPPV-d-OPEO in solution are reported in this paper. Effects of the amphiphilic behavior on fluorescence emissions of the dendrons are discussed.
