A hydrogen sulfide-sensitive supramolecular polymer constructed by crown ether-based host–guest interaction and Ag-coordination.

Highlights • A new supramolecular polymer was fabricated by crown ether-based host‒guest interaction and Ag-coordination. • The supramolecular polymer displayed sensitive property to H 2 S. • The supramolecular polymer was made into a thin film and used as a convenient test kit for detecting H 2 S. • The thin film was more stable under moisture and sunlight than simple silver ion. Abstract A supramolecular polymer was fabricated via crown ether-based host–guest interaction and Ag-coordination. It displayed hydrogen sulfide sensitive property. In addition, the supramolecular polymer was made into a thin film which can be used to detect hydrogen sulfide. [ABSTRACT FROM AUTHOR]
