Title:
CARBON QUANTUM DOT AND SYNTHESIS METHOD THEREFOR, THIN FILM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/248830
Kind Code:
A1
Abstract:
Provided are a carbon quantum dot, a synthesis method therefor, a thin film and an electronic device, the carbon quantum dot containing a structure represented by formula (2). In formula (2), L is a group represented by formula (1): in formula (1), R1, R2, R4, R5, R7 and R8 are each independently selected from a group consisting of the following groups: hydrogen, alkyl, amino, carboxyl, hydroxyl, nitryl, sulfonyl, cycloalkyl, heteroalkyl, aralkyl, alkoxy, aryloxy, haloalkyl, haloalkoxy, phosphino, and combinations thereof; R3, R6 and R9 are each independently selected from a group consisting of the following groups: substituted or unsubstituted hydroxyl, amino, ethylamino, diethylamino, benzoate, hydroxybenzoate and ethyl benzoate. The carbon quantum dot provided is high in fluorescence quantum yield, good in stability and narrow in half-peak width, and may be used in films and electronic devices.
