ABSTRACT:
A calixarene dimer of the general formula (I-G), comprising a first calixarene moiety I and a second calixarene moiety G, wherein: L is [—CH2—] or [—O—CH2—O—] and is the same or different between each aryl group; R5is H, NO2, halogen, or C1-C10aliphatic hydrocarbyl group, C6-C20aryl group, C6-C20hydrocarbylaryl group, any of which is optionally substituted by one or more halo or oxo groups or interrupted by one or more oxo or amide groups, and R5is the same or different on each aryl group; R1comprises a carboxy group which is or is not protonated or protected; two groups out of R2, R3and R4are H; the one group out of R2, R3and R4not being H comprises at least one atom of one or more of O and S, the said at least one atom being capable of causing the calixarene to be adsorbed onto the surface of the substrate; and the one group out of R2, R3and R4not being H being conjugated to the second calixarene moiety G. The calixarene dimers may be incorporated into sensors. Methods of making the calixarene dimers are disclosed.
