Derivatization of an elemental carbon surface is accomplished by exposing the carbon surface to an aprotic solvent containing a hydrazone molecule of formula (I) or the corresponding salt of formula (II) wherein R
1
is an organic group, and R
2
is an organic group or hydrogen and decomposing the hydrazone in the presence of elemental carbon to create a carbene moiety of formula (III): which attaches to the carbon surface. The attached groups may be redox active so that the derivatized carbon may be used in an electrochemical sensor.
通过将含有式(I)的
肼分子或式(II)对应的盐的无质子溶剂暴露在
碳表面上,并在元素
碳的存在下分解
肼分子,从而实现元素
碳表面的衍生化。其中,R1是有机基团,R2是有机基团或
氢。分解后,生成式(III)的卡宾基团,它会附着在
碳表面上。附加的基团可能是可
氧化还原的,因此衍生化的
碳可以用于电
化学传感器。
