A multi-responsive luminescent sensor based on flexible and ultrastable Zn-MOF@SWCNT hybrid nanocomposite film

Abstract The application of metal–organic frameworks (MOFs) as a sensing layer has been attracting great interest over the last decade, due to their uniform properties in terms of high porosity and tunability, which provides a large surface area and/or centers for trapping/binding a targeted analyte. Here we report the fabrication of a highly sensitive luminescent sensor that is based on composite thin films of Zn-MOF and single-wall carbon nanotubes (SWCNTs). The approach presented here is facile and paves a promising path towards enhancing the sensitivity of MOF-based sensors.
