Liquid and solid-state study of antioxidant quercetin donor and TCNE acceptor interaction: Focusing on solvent affect on the morphological properties

The solvent significantly affects the structural morphology of the CT product formed between the antioxidant quercetin and the TCNE acceptor. In less polar solvent (EtOH), the particles of the product have short rod-like shape. The morphology of these particles changed to coral-like shape in MeOH solvent. In more polar solvent (MeCN), the particles of the product have cotton-like shape.330
