We report significant improvements in the optical gain properties of highly oriented films of the fluorene-based conjugated polymer poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT). We demonstrate amplified spontaneous emission (ASE) in optically

We report a study of the amplified spontaneous emission (ASE) in highly oriented films of dioctyl substituted polyfluorene (PFO). We demonstrate amplification of blue light via ASE measurements on optically pumped aligned PFO planar asymmetric wavegu

Understanding the molecular alignment of conjugated polymers within thin-film samples is essential for a complete picture of their optical and transport properties, and hence for the continued development of optoelectronic device applications. We rep

Polarized confocal Raman mapping is used to characterize the degree of molecular alignment in spin coated conjugated polymer thin films. To this end, the polarization selection rules of a specific Raman active mode are employed to infer indirectly th

Liquid crystalline conjugated polymers have potential applications as inexpensive, easy to process polarized back lights for liquid crystal displays. Three ‘Hairy rod’ type conjugated polymers, namely Poly(9,9-dioctylfluorene) [PFO] and two alter

Conjugated copolymers of 9,9-dioctylfluorene alternating with benzothiadiazole and dithiophene moieties in the main chain were found to be 'hairy rod' type thermotropic liquid crystalline polymers as well as yellow to red photoluminescence emitters.

From photophysical evidence, we suggest a structural model based on intrachain ordering that can account for the thermoreversible changes of the absorption spectrum of poly(9,9-dioctylfluorene) films under certain physicochemical treatment protocols.

As a novel approach to polarized electroluminescence, we report on the synthesis of the conjugated reactive mesogen 2-methyl-1,4-bis[2-(4-acryloylpropyloxyphenyl)ethenyl] benzene (chemical structure DSB MeO 3 O-acryl). DSB MeO 3 O-acryl was character

SUMMARY AND CONCLUSION We have demonstrated that the monodomain-alignment of novel nematic fluorene bisacrylates can be preserved by in-situ photopolymerization within their liquid crystalline phase. This leads to high dichroic ratios of absorption a
