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。
