Recently, intensive research interests have been focused on the formulation of water soluble and highly fluorescent carbon dots (CDs) as new functional carbon nanomaterials. While most of previous researches have attempted the utilization of A3 (A: -COOH) and B2 (B: -NH2) type polyamide monomer sets for the synthesis of CDs through either hydrothermal or microwave operation, the utilization of A2 and B3 type has advantage because various A2 types of dicarboxylic acid are naturally abundant. In the detailed experiments, succinic acids (SA) and tris(2-aminoethyl)amine (TAEA) have been used as both A2 and B3 type polyamide monomer sets. The resulting CDs demonstrated the quantum yield (QY) up to 17.5% and intense blue fluorescence upon the irradiation of ultraviolet light. Through the good solubility of prepared CDs in polar solvents including water, methanol, and ethanol, various applications of CDs are able to be attempted. 2016년 한국교통대학교 지원을 받아 수행하였음 |
