Abstract: A device for delivering an ionic material includes a storage module including a reservoir configured to store the ionic material, a bipolar membrane configured to pass the ionic material in a single direction based on an ionic current, electrodes, disposed on a lower end of the reservoir and an upper end of the bipolar membrane, respectively, configured to form an electric field generating the ionic current, and a control module configured to control either one or both of a release amount and a release period of the ionic material passing through the bipolar membrane by adjusting a direction and an intensity of the electric field.

Abstract: A synthetic method of a fused heteroaromatic compound includes preparing a first intermediate represented by Chemical Formula 1, obtaining a second intermediate by reacting the first intermediate and an aldehyde compound, obtain a third intermediate by performing deprotection and reduction reactions on the second intermediate, and obtaining a fused heteroaromatic compound by performing a cyclization reaction on the third intermediate.
