摘　　要：层状复合氢氧化物(LDHs)是一种层板金属元素和层间离子可调的无机层状材料,利用其独特的插层组装特性,基于静电、氢键、范德华力等相互作用力,功能性荧光客体分子可与LDHs纳米片复合构筑多功能荧光薄膜材料.LDHs薄膜基荧光材料用于荧光传感器,在有机挥发性气体(VOCs)、温度、压力、重要生物分子等的检测中显示了良好性能.本文总结了LDHs复合薄膜的制备方法以及近年来其在纳米荧光传感领域的进展,并对其未来发展做出了展望.Layered double hydroxides(LDHs)are a class of two dimensional anionic lamellar materials,which are made up of metal cations within the hydroxide layers and adjustable interlayer anions.Taking advantage of intercalation and assembly properties of LDHs,LDHs-based fluorescent films have been fabricated based on the electrostatic interaction,hydrogen bonding,van der Waals interaction.Furthermore,LDHs-based fluorescent films have prospective application to fluorescent nanosensors,which can detect the leakage of volatile organic compound(VOCs),and monitor temperature,pressure and some significant biomolecules.This review summarizes the preparation and recent research progress of LDHs-based fluorescent nanosensors.
