Photoluminescent carbon dots were synthesised directly by thermopyrolysis of 1,4-addition polymers, allowing precise control of their properties. The effect of polymer composition on the properties of the carbon dots was investigated by TEM, IR, XPS, elemental analysis and fluorescence analysis, with carbon dots synthesised from nitrogen-containing polymers showing the highest fluorescence. The carbon dots with high nitrogen content were observed to have strong fluorescence in the visible region, and culture with cells showed that the carbon dots were non-cytotoxic and readily taken up by three different cell lines.
通过1,4-加成聚合物的热解直接合成了光致发光碳点，从而能够精确控制其性质。通过透射电子显微镜（TEM）、红外光谱（IR）、X射线光电子能谱（XPS）、元素分析和荧光分析研究了聚合物组成对碳点性质的影响，结果表明，由含氮聚合物合成的碳点具有最高的荧光强度。观察到高氮含量的碳点在可见光区域具有强烈的荧光，并且与细胞共培养表明这些碳点无细胞毒性，并且易于被三种不同的细胞系摄取。
