    • A self-replicating monolayer system employing polymerization of monomers or nanoparticle ensembles on a defined template provides a method for synthesis of two-dimensional single molecule polymers. Systems of self-replicating monolayers may be used as templates for the growth of inorganic colloids. A preferred embodiment is a SAM-based replication, wherein an initial monolayer is patterned and used as a template for self-assembly of a second monolayer by molecular recognition. Once the second monolayer has formed, it is polymerized in place and the two monolayers are separated to form a replicate. Both monolayers may then function as templates for monolayer assemblies. A generic self-replicating monomer unit suitable for use in one embodiment comprises a polymerizable moiety attached by methylene repeats to a recognition element and an ending unit that will not interfere with the chosen recognition chemistry. The recognition element is self-complementary, unless a set of two replicating monomers with compatible cross-linking chemistry is employed. In a two-component replication system utilizing two different kinds of recognition chemistries, the initial template undergoes replication cycles, while maintaining the two-dimensional segregation of the two types of monomers. During subsequent replications, the component domains experience little or no mixing, allowing the two-component, patterned assembly to be exponentially replicated. After replication, selective mineralization and/or electroless plating may produce a two-dimensional inorganic sheet having patterned domains within it.
    • 使用单体或纳米颗粒聚合体在定义的模板上进行聚合的自复制单层体系提供了合成二维单分子聚合物的方法。 自复制单层的系统可以用作无机胶体生长的模板。 优选的实施方案是基于SAM的复制,其中将初始单层图案化并用作通过分子识别自组装第二单层的模板。 一旦形成了第二个单层,就将其聚合,将两个单层分离形成一个复制体。 然后两个单层可以用作单层组件的模板。 适用于一个实施方案的通用自复制单体单元包括通过亚甲基重复序列连接到识别元件的可聚合部分和不干扰所选择的识别化学的结束单元。 识别元件是自互补的,除非使用具有相容的交联化学的两组复制单体。 在使用两种不同类型的识别化学物质的双组分复制系统中,初始模板经历复制循环,同时保持两种类型的单体的二维分离。 在随后的复制过程中,组件域经历很少或不混合,允许双组分图案化组件以指数方式复制。 复制后,选择性矿化和/或化学镀可以产生其内具有图案区的二维无机片。
