Anthraquinone-based chemosensor L with pyridine units as additional functional groups has been found to show pH-dependent multiple coordinationmodes towards differentmetal ions (Co2+, Ni2+ and Cu2+). Based on these different absorption changes, this differential colorimetric chemosensor L has found promising applications as a multiple-mode molecular logic system, i.e., OR, three - input NOR, three - input INHIBIT, TRANSFER and 1:2 DEMUX.
