Abstract

Solution state absorption and fluorescence of samples of fully and partially conjugated MEH-PPV at 77K and 300K have been measured to probe the distribution of conjugated segments within the polymer. The absorption of the partially conjugated polymer is at shorter wavelength and has a larger full width at half maximum at all temperatures than that of the fully conjugated polymer. The spectra are analysed by considering the polymer chain to be made up of a number of non interacting conjugated segments. Using this approach it is possible to explain all the features seen in the spectra.
