Forming water-soluble supramolecular polymer and AIEE hydrogel: two novel approaches for highly sensitive detection and efficient adsorption of aldehydes

Abstract

Herein, we report two novel approaches for highly sensitive detection and efficient adsorption of formaldehyde and 3-fluorobenzaldehyde by forming a water-soluble supramolecular polymer and an aggregation-induced emission enhancement (AIEE) hydrogel, respectively. The host compound DTA could highly selectively and sensitively detect formaldehyde by forming water-soluble supramolecular polymer in pure water. The LOD of DTA for formaldehyde was 1.79×10-8 M. More importantly, the DTA could also efficiently adsorb formaldehyde from its water solution, and the adsorption percentage is 98.41%. In addition, the DTA could also selectively detect 3-fluorobenzaldehyde from its isomers through forming the supramolecular AIEE hydrogel. The LOD of DTA for 3-fluorobenzaldehyde was 8.87×10-9 M, this result reached an ultrasensitive level. These methods are novel and useful approaches for highly sensitive detection and adsorption of aldehydes, as well as new ways for the construction of water-soluble supramolecular polymer materials and hydrogels.
