Cobalt–ruthenium bypiridine–oxalate metal–organic frameworks (MOFs) were synthesized via a solvothermal method with a custom-designed reactor that permits stirring, which can result in changes in the morphology of the structures. In this work, we performed a morphological and structural study of MOFs with varying tris(2,2,bipyridyl) and diclororuthenium(II) hexahydrate (Ru(bpy)32+) concentrations, demonstrating changes in the size of the MOFs, and these MOFs were used as the luminescent materials in an electrochemiluminescent (ECL) system for glyphosate (Gly) detection, which acts as a coreactant in the light emission of Ru(bpy)32+. Gly is the most commonly used herbicide worldwide, and our system has a calibration curve range of 10–70 ppm, with a detection limit of 7.6 ppm.
