Modification of Croconic Acid Structure

Event Center A & B

Croconic acid is an organic molecule that possesses large electric ferroelectricity of 20 uC/cm2 at room temperature due to the intermolecular H-bonds, as shown in Figure 1. The purpose of this research is to synthesize a derivative of croconic acid and search for the effect of functional groups on the H-bond and eventually on the ferroelectricity, as shown in Figure 2. In this project, the derivative was synthesized via the conventional oximation organic synthesis route. The synthesis reaction is conducted at pH 3 and pH 4, which includes heating of a mixture of both croconic acid and hydroxylamine. After the reaction is completed, the mixture solution is analyzed by using 13C Nuclear Magnetic Resonance (NMR) spectroscopy to predict the structure of the molecule. Interpretation of the mixture solution using NMR spectra are still ongoing.
