  2. 1. Single-­molecule spectroscopy of π-­conjugated polymers

    Author : Oleg Mirzov; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence lifetime; low temperature; spectral diffusion; blinking; MEH-PPV; Single-molecule spectroscopy; π-conjugated polymers; 2D polarization; Monte Carlo; energy transfer;

    Abstract : When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. READ MORE

  4. 2. Conformational and Dynamical Aspects of Conjugated Polymers and Oligomers of Interest for Photoluminescence

    Author : Mette Grage; Kemisk fysik; []
