摘要
Farication of novel amphiphilic light-emitting dendrons with oligo(phenylenevinylene) core branches and oligo(ethylene oxide) terminal chains (OPV-d-OEO) was presented. It was observed that dendrons possess CAC values of 1.60 and ).40 mg/mL, respectively. It was found that the amphiphilic characteristics and resultant aggregation behaviors led to concentration and solvent polarity-dependent fluorescence in solutions. The results show that the solution photoluminescence (PL) spectra for these dendrons display red shifts with increasing concentration and/or solvent polarity.
