我们报告了在低分子量盐水凝胶内掺入功能化碳纳米点,增强了凝胶和碳纳米材料的凝胶化和荧光性质。报道了将官能化碳纳米点掺入衍生自5-氨基水杨酸的新型低分子量盐水凝胶中。碳量子点导致显著增强的凝胶化性质,而疏水凝胶内的包含物导致碳纳米材料的显著荧光增强。所得的混合CD凝胶表现出有用的传感器响应重金属离子,特别是Pb 2+。
We report the incorporation of functionalised carbon nanodots within a low molecular weight salt hydrogel enhancing the gelation and fluorescence properties of both the gel and carbon nanomaterial. The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation properties, while inclusion within the hydrophobic gel results in a dramatic fluorescence enhancement for the carbon nanomaterials. The resulting hybrid CD gels exhibit a useful sensor response for heavy metal ions, particularly Pb2+.
