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.

量子点（QDs）薄膜的荧光效率和稳定性都是光电器件的关键，但相对难以同时提高。本文中，报道了容易合成乙烯基醚封端的液晶。基于主体乙烯基醚液晶，聚合物分散的乙烯基醚液晶（PDVLC），聚合物分散的交联乙烯基醚液晶（PDCVLC）和含氟聚合物分散的交联乙烯基醚液晶（F-PDCVLC） QDs薄膜是通过双步聚合连续制造的。结果，PDVLC膜可以实现荧光增强和调谐，而PDDCVLC膜不仅保持PDVLC膜的荧光增强，而且提高了耐水性。更重要的是，交联膜的形成使得制造QDs膜变得方便。随后，F-PDCVLC膜可以通过引入含氟单体以增强疏水性能来进一步改善耐水性。这种独立的（F-）PDCVLC膜可能为实现QD膜性能的优化提供一条新途径。
