Fluorescence blinking in MEH-PPV single molecules at low temperature

Mirzov, Oleg LU ; Cichos, F ; von Borczyskowski, C and Scheblykin, Ivan LU orcid (2005) In Journal of Luminescence 112(1-4). p.353-356
Abstract
Fluorescence intensity transients of single molecules of the conjugated polymer poly[2-methoxy,5-(2-ethylhexyloxy)-p-phenylene-vinylene] (MEH-PPV) were studied at 15 K. Fluorescence blinking behavior was observed despite the expected low-temperature suppression of energy migration in such disordered molecular systems. Presence of the fluorescence blinking effect at 15K indicates that the single molecules possess a collapsed conformation with characteristic size of not more than several nanometers, which corresponds to only a few exciton hops over a polymer chain.
