A homochiral, square-shaped, D2 symmetrical nanosized metal-linked macrocycle is able to form stable complexes with ferrocene in polar solvents, with detection achieved by means of multiple outputs (optical/chiroptical spectroscopies and cyclic voltammetry). Selective sensing using chiroptical spectroscopy in the presence of interfering analytes is demonstrated.
