N2 - A novel oxovanadium complex, prepared from the reaction of hydrated VOSO4 with an azo-ligand derived from the synthesis of 2‑hydroxy-5-(phenyldiazenyl)benzaldehyde and L‑serine, was structurally investigated using powder XRD, Rietveld analysis, infrared, ultraviolet-visible (UV-vis), circular dichroism (CD), fluorescence measurements, cyclic voltammograms (CV), electron spin resonance (ESR), and a superconducting quantum interference device (SQUID). In addition, the stability of the complex in the presence of laccase was also explored. The UV–vis absorption spectra of the studied complex exhibited a maximum degradation of ∼ 60% and minimum degradation of approximately ∼ 10% after two days of exposure to laccase based on the decrease in absorbance induced by azobenzene π-π* absorption. However, the rate of degradation is considerably slower than predicted.
