Cho, Eunbee published the artcileA Single-Benzene-Based Fluorophore: Optical Waveguiding in the Crystal Form, Name: N,N-Dimethyl-N’-(3-thioxo-3H-1,2,4-dithiazol-5-yl)formimidamide, the publication is ChemPlusChem (2019), 84(8), 1130-1134, database is CAplus and MEDLINE.
A single-benzene-based, blue-emissive di-Et 2,5-dihydroxyterephthalate (DDT) was prepared by Fischer esterification of 2,5-dihydroxyterephthalic acid (DHT) and ethanol. The strong fluorescence in both the solution and the solid state from such a simple framework stemmed from the push-pull structure of the electron-donating hydroxy groups and the accepting carbonyl groups, as well as structural planarity from intramol. hydrogen bonds. The strong intermol. hydrogen bonds enabled DDT to crystallize easily. The color CCD imaging technique showed efficient 1D optical waveguiding with a large optical loss coefficient of 0.15 dB/μm. DDT has potential application in optical sensors, photonic devices, and optoelectronic communication, because of its highly ordered structure and light-emitting ability.
