High-mobility light-emitting semiconductor and its preparation method, use and application method

Abstract

The invention discloses a high-mobility light-emitting semiconductor and its preparation method, use and application method. The preparation method of the high-mobility light-emitting semiconductor includes Suzuki coupling chemistry between aryl bromide or iodide and aryl boronic acid or borate ester Reaction, the method of applying high-mobility light-emitting semiconductors to devices, the device adopts a bottom-gate top-contact device structure, the gate uses n-type doped silicon, and a layer of 300nm SiO is thermally grown 2 As an insulating layer, before depositing the organic semiconductor layer, the gate insulating layer was modified with OTS in a vacuum furnace at 120°C to form a single-layer OTS modified layer; the modified layer was cleaned with chloroform, n-hexane, isopropanol and acetone successively, and used High-mobility light-emitting semiconductors are coated by spin coating. The material synthesized by the invention exhibits the property of aggregation-induced luminescence, while traditional fluorescent dyes have the phenomenon of aggregation-induced fluorescence quenching under high concentration conditions, thus effectively overcoming the defects of traditional fluorescent dyes.
