Tuning of polyarylene ether nitrile emission profile by using red-emitting gold nanoclusters via fluorescence resonance energy transfer†
Abstract
Fluorescence resonance energy transfer (FRET) between blue fluorescent polyarylene ether nitrile (PEN) and red-emitting gold nanoclusters (Au NCs) has been firstly reported in this work. Consequently, the emission profile of PEN can be readily tuned depending on the loading content of Au NCs.
