Overview

Description

Amines are nitrogen-containing organic compounds that can be regarded as hydrocarbon derivatives of ammonia. Nitrogen atoms in amine molecules have unshared electron pairs, so amines generally have strong electron donating ability, and are easy to form hydrogen bonds with water, and have good water solubility. Many amine compounds are important substances for sustaining life activities, so the quantum dots prepared based on amines have good biocompatibility. Nitrogen atoms can be used as doping elements or amino groups with strong electron donating ability can be used as fluorescent auxiliary units to improve the optical properties of quantum dots. At the same time, the amino groups on the surface of QDs are beneficial to their specificity to target analytes when they are used as probes, and can also enhance the water solubility of QDs and improve the surface modification and functionalization capabilities of QDs.
