Permselective Two-Dimensional Polymer Film-Based Chemical Sensors

Abstract

A surface-enhanced Raman scattering (SERS) based chemosensor that works without tedious pre-treatment processes has been fabricated by depositing cucurbit[6]uril-based two-dimensional polymers (CB[6]-2DPs) on a plasmonic substrate. The permselectivity of CB[6]-2DPs, and ultrahigh sensitivity and fingerprinting capability of SERS enabled the identification of a specific chemical present in a complex mixture.
