Abstract
This paper describes a simple strategy for synthesizing poly(9,9-dialkylfluorene-2, 7-vinylenes) (PFV) having high molecular weight by Gilch polymerization method. The structure and optical properties of PFV were characterized by gel permeation chromatography (GPC), NMR spectroscopy, UV-Vis spectroscopy, and fluorescence spectroscopy. UV-Vis absorption spectra showed the broad absorption band with λmax = 414 nm. It exhibited a greenish fluorescence at λmax emission = 453 nm with shoulder at 488 nm. Similarly, photoluminescence spectra of powder samples of PFV showed λmax emission = 505 nm with shoulder at 535 nm.
