Progress in the development of phytochemistry has delivered advancement in materials functionality for range of inter/trans-disciplinary application. Here, we investigated the structural functionality of chemically synthesized phytoconstitutent, chalcone (butein) and flavanone (butin). Photoactive and electroactive behavior of butein and butin were comprehensively studied using UV–vis absorbance, photoluminescence and cyclic voltammetric techniques. Surface morphology of the butein and butin powders was characterized from scanning electron microscope at an operating voltage of 10 kV. Significant ultraviolet absorbance property are observed from butein and butin due to the distribution of π → π* and n → π* transitions. Photoluminescence emission spectra of the prepared materials are well resolved at visible region via keto-enol tautomerization and can be influenced by solvent pH. Cyclic voltammetric studies on the prepared materials enabled a direct electron-transfer reaction at gold-screen printed electrode, indicating the feasibility for analytical validation in herbal industries. Existence of multiple electroactive hydroxyl groups makes butein and butin a redox-functional species at electrode interface. Dispersion ability in aqueous and organic solvents makes butein and butin suitable for variety of photochemical applications. This phytochemical material offers new degrees of optical and redox functionality similar to inorganic nanostructures, in addition to inherent bioactivity, that may be advantageous for further biomedical function.
