Single molecule spectroscopy reveals dark, non-emissive regions in isolated conjugated polymer chains. Does energy-funneling concept really work?
关键字：non-emissive regions
Conjugated polymers dispersed at a very low concentration in a non-fluorescent matrix (e.g. PMMA)can be studied at single chain level by single molecule spectroscopy (SMS) techniques. Theenergy-funneling concept is the paradigm in SMS ...
