From: Conformation and physics of polymer chains: a single-molecule perspective
Spectral characterization of single chains of the PPV family of conjugated polymers. (a,b) Fluorescence spectra and evolution in time for MEH–PPV cast from (a) toluene (poor solvent) and (b) chloroform (good solvent). Modified after Ref. 28, reproduced with permission (© 2000 NAS). (c) Relative spectral shift Sr during photobleaching of long-chain MEH–PPV and short-chain DOO–PPV. Negative values of Sr correspond to blue shift. Modified after Ref. 36, reproduced with permission (© 2006 APS). (d) Bimodal histogram of fluorescence peak wavelengths of single chains of MEH–PPV in a thin-film polycarbonate matrix. Modified after Ref. 46, reproduced with permission (© 2000 AAAS). (e) Multimodal histogram of fluorescence peak wavelengths of single oriented nanoparticles of MEH–PPV. Modified after Ref. 50, reproduced with permission (© 2003 ACS).
