The growing number of applications of ionic liquids (ILs) in industry have brought attention to the green credentials of synthesis, as well as their cytotoxicities and ecotoxicities both for their use and accidental leakage into the environment. With the abovementioned properties in mind, we designed a class of ILs with either cations bearing a gluconamide motif and aliphatic side chains or the anion incorporating a gluconic acid (derived from food waste) moiety.

ZnO-based nanomaterials are a subject of increasing interest within current research, because of their multifunctional properties, such as piezoelectricity, semi-conductivity, ultraviolet absorption, optical transparency, and photoluminescence, as well as their low toxicity, biodegradability, low cost, and versatility in achieving diverse shapes.

New pentanuclear porphyrazine complexes of formula [{Pd(CBT) 2 } 4 LM]·xH 2 O (L = tetrakis-2,3-[5,6-di(2-pyridyl)pyrazino]porphyrazinato anion, CBT = m-carborane-1-thiolate, and M = Mg II (H 2 O), Zn II , Pd II ) were prepared in good yield as dark green hydrated amorphous solids by reaction of the respective pentanuclear species [(PdCl 2 ) 4 LM] with m-carboran-1-thiol in CH 3 CN. Physicochemical characterization of the new species was carried out by elemental and thermogravimetric analysis along with IR and 1 H/ 13 C NMR measurements.
