Inclusion complexes of a new host, 4,5-bis(4-methoxyphenyl)-2-(4-nitrophenyl)-1H-imidazole, with various guests

Abstract

The title host compound forms crystalline inclusion complexes, the colour of which depend on the guest. It forms a complex with 2-phenylethanol (6), which when heated changes colour and emits the characteristic fragrance of the latter. The complex formed with trichloroacetic acid shows solid-state fluorescence.
