Correlation Analysis of Fluorescence Intensity and Fluorescence Anisotropy Fluctuations in Single-Molecule Spectroscopy of Conjugated Polymers.
Single-molecule spectroscopy techniques are used to investigate time fluctuations of the fluorescence properties of two different types of conjugated polymer, a polythiophene derivative (PDOPT) and a phenylene vinylene derivative (MEH-PPV), at 100 and 293 K. Linear correlation coefficients between fluorescence intensity and polarization are used to characterize fluctuations. We are able to disting
