    • A ligand layer on a metal surface is capable of being reversibly switched between adhesion and deadhesion. The ligand layer includes substituted pyridine dimers and/or pyridine trimers which are selected from the group consisting of: with R1 through R6 being able to be equal or different and being selected from the group consisting of —R—CH(O)CH2, OH, —O—R, NR2, NHR, NH2, CO2H, CO2R, R and H. R is selected from the group consisting of alkyl and aryl residues with the proviso that not all residues R1 through R6 are hydrogen atoms at the same time. R7 is selected from the group consisting of —R—CH(O)CH2, OH, —O—R, NR2, NHR, NH2, CO2H, CO2R, CONHR, R and H, with R being selected from the group consisting of alkyl and aryl residues. Y is selected from the group consisting of silicon, carbon, nitrogen, phosphorus and oxygen atoms, and X is an oxygen, sulfur or phosphorus atom, and n having the value 0 or 1.
    • 金属表面上的配体层能够在粘合和粘合之间可逆地切换。 配体层包括取代的吡啶二聚体和/或吡啶三聚体,其选自:R 1至R 6能够相同或不同,并且选自-R-CH(O)CH 2,OH ,-OR,NR 2,NHR,NH 2,CO 2 H,CO 2 R,R和H.选自烷基和芳基残基,条件是不是所有的残基R1至R6都是同时为氢原子。 R 7选自-R-CH(O)CH 2,OH,-OR,NR 2,NHR,NH 2,CO 2 H,CO 2 R,CONHR,R和H,其中R选自烷基和芳基 残留物。 Y选自硅,碳,氮,磷和氧原子,X为氧,硫或磷原子,n为0或1。
