A system, device and methods, for determining at least two analytes, wherein the system and device include at least one resonant sensor circuit that includes a sensing material that predictably affects the resonant complex impedance response of a sensor electrode. The sensing material has at least two material properties that change when the materials are exposed to two or more analytes. The system and device also include a processor that generates a multivariate sensor response pattern that is based at least in part on a change in the two material properties of the sensing material.

The present invention provides novel ketopyrroles having structure XXIV wherein R2 is independently at each occurrence a deuterium atom, a halogen, a nitro group, an amino group, a C3-C40 aromatic radical, a C1-C50 aliphatic radical, or a C3-C40 cyclcoaliphatic radical; “a” is an integer from 0 to 3; and X1 and X2 are independently at each occurrence a bromine atom, a hydroxy group, or the group OR10, and wherein the group R10 is independently at each occurrence a deuterium atom, a halogen, a nitro group, an amino group, a C3-C40 aromatic radical, a C1-C50 aliphatic radical, or a C3-C40 cyclcoaliphatic radical. Ketopyrroles XXIV are useful ligands for the preparation of Type (1) and Type (2) organic iridium compositions. In one aspect, the present invention provides deuterated analogs of XXIV. Organic iridium compositions are useful in the preparation optoelectronic devices, such as OLED devices and photovoltaic devices exhibiting enhanced performance characteristics.
