A process for producing a substrate having a functionalised surface, which process comprises contacting the substrate with a carbene precursor, which carbene precursor is a compound of formula (III) or (IV) whose substituent groups are defined herein: (b) generating a carbene reactive intermediate from the carbene precursor so that it reacts with the substrate to functionalise the surface, thereby yielding an activated substrate; and (c) further functionalising the activated substrate obtained in (b). In (c), the activated substrate may be further functionalised by treating the activated substrate with a diazonium salt for the introduction of colour and/or another desired activity, and/or by treatment with hydrogen peroxide to produce a biocidal substrate. The invention further relates to carbene precursor compounds for use in the surface functionalisation process, and to processes for preparing certain precursor compounds.
一种制备具有功能化表面的基板的方法,该方法包括将基板与卡宾前体接触,该卡宾前体是具有公式(III)或(IV)的化合物,其取代基团在此定义:(b)从卡宾前体生成卡宾反应中间体,使其与基板反应以功能化表面,从而产生活性基板;和(c)进一步功能化在(b)中获得的活性基板。在(c)中,可以通过用重氮盐处理活性基板来进一步功能化活性基板,以引入颜色和/或其他所需的活性,和/或通过
