Abstract
Fluorescence efficiency and stability of quantum dots (QDs) film, which are both key for optoelectronic device, are relatively difficult to be improved simultaneously. Herein, the facile synthesis of vinyl-ether terminated liquid crystals was reported. Based on the host vinyl-ether liquid crystals, the polymer dispersed vinyl-ether liquid crystals (PDVLC), polymer dispersed crosslinked vinyl-ether liquid crystals (PDCVLC) and fluorine-containing polymer dispersed crosslinked vinyl-ether liquid crystals (F-PDCVLC) QDs films were fabricated in succession by dual-step polymerization. As a result, the PDVLC film can realize fluorescence enhancement and tuning, whereas the PDCVLC film not only maintain fluorescence enhancement of PDVLC film but also improve the water-resistant performance. More importantly, the formation of crosslinked film makes it convenient to fabricate QDs film. Subsequently, the F-PDCVLC film can further improve the water-resistant properties by introducing fluorine-containing monomers to enhance the hydrophobic performance. This free-standing (F-) PDCVLC film may offer a new avenue to realize the optimization of QDs film performance.
