New Emissive Materials

About

Invention A unique system in which luminogen aggregation played a constructive role in the light-emitting process has been developed. The novel phenomenon ‘‘aggregation-induced emission’’ (AIE) was identified. By adopting the working principle of the AIE process, a series of new AIE luminogens was designed. AIE molecules are emissive in aggregation or solid state. Due to this AIE feature, AIE molecules can be tuned to have different responses under different conditions, based on molecular designs. Therefore, turn on/off sensors can be developed. The applications can be extended to functional materials such as solid-state emitter for OLEDs.   Marketing Opportunity Luminescence behaviors of molecules are normally investigated in the solution state, but they are practically used as materials in the solid state. It is an obstacle to applications of luminogen in high concentration and in solid state due to the aggregation-caused quenching effect. The newly developed AIE luminescent materials can be used in solid state for OLED applications. Also, they can be used as chemosensors/probes for CO2, VOCs, pH, explosives and ions.   Key Benefits Novel light emitting platform technology High sensitivity and selectivity in rapid detection Tailor-made molecules for wide range of applications
