1. A sensing method comprising:
exposing a fluid containing at least one analyte to a sensor construct comprising a hexasubstituted benzene having at least one sensing functionality capable of undergoing molecular association with the at least one analyte, wherein the fluid comprises an oilfield fluid comprising oil, gas, a treatment fluid, produced water, or any combination thereof;
determining an analytical response of the hexasubstituted benzene in the presence of the at least one analyte; and
correlating the analytical response or a change thereof to an amount of the at least one analyte present in the fluid.
