报道了在脂肪族双膦酸（bisPAs）单层膜上成功地转印金属薄膜的方法。这些单分子膜是从等离子体生长的氧化铝上的溶液制备的，并且与烷基单膦酸（monoPAs）的类似单分子膜进行比较以获得转印功效。水接触角和原子力显微镜测量表明均匀的膜形成的两类膦酸。蒸发的Au/Ti膜使用图案化的聚合物印模制备，并转印到各种膦酸酯单层上;该过程导致bisPA单层的产率接近100%，但对于monoPA仅测量到较差的结果。我们将bisPA单层上的高效印刷归因于远端膦酸基团与通过其天然Ti氧化物终止的压印粘附金属膜之间形成的强化学键。
The successful transfer printing of thin metal films onto monolayers of aliphatic bisphosphonic acids (bisPAs) is reported. These monolayers were prepared from solution on plasma-grown aluminum oxide, and were compared with analogous monolayers of alkyl monophosphonic acids (monoPAs) for transfer printing efficacy. Water contact angle and AFM measurements indicated uniform films formed from both classes of phosphonic acids. Evaporated Au/Ti films were prepared using patterned polymeric stamps, and were transfer printed onto the various phosphonate monolayers; this process resulted in close to 100% yield for bisPA monolayers, but only poor results were measured for the monoPAs. We attribute efficient printing onto bisPA monolayers to the formation of strong chemical bonds between distal phosphonic acid groups and the stamp-adhered metal film via its native Ti-oxide termination.
