High mobility light emitting semiconductor and preparation method, use and application method thereof

Abstract

The invention discloses a high mobility light emitting semiconductor and a preparation method thereof, use and application method thereof. The preparation method of a high mobility light emitting semiconductor comprises a Suzuki coupling chemical reaction between an aryl bromide or an iodide and an aryl boronic acid or a boric acid ester. In the application method of the high mobility light emitting semiconductor to a device, the device uses a bottom gate top contact device structure, the gate uses n-type doped silicon, and a 300 nm SiO2 is thermally grown as an insulating layer, before depositing the organic semiconductor layer, the gate insulating layer is modified by OTS in a vacuum furnace at 120 DEG C to form a single-layer OTS modified layer; the modified layer is successively washedwith chloroform, n-hexane, isopropanol and acetone, and the high mobility light-emitting semiconductor is utilized for film coating in a manner of spin coating. The material synthesized by the invention exhibits the property of aggregation-induced luminescence, and the conventional fluorescent dye has the phenomenon of aggregation-induced fluorescence quenching under high concentration conditions. Therefore, the invention effectively overcomes the defects of the conventional fluorescent dye.
