Azo host compounds undergo rapid and clearly visible colour changes from yellow to bright orange/red on complexation with guest molecules, while no colour change is noted in the absence of complexation. This provides a rapid screening method for potential guest compounds as the first step towards the development of guest specific host compounds for use in sensors relying only on a simple, visible colour change readout mechanism
