Two triphenyleneethynylene derivatives, 1OH and 2, self-assemble a patterned monolayer (ML) at the solution-graphite (HOPG) interface. The four molecule unit cell of the ML, (1OH1OH22), spans 19 nm and contains adjacent columns of 1OH molecules spaced by 4.7 nm. Following ML assembly, a disulfide is appended to the alcohol group on each 1OH molecule and used to capture 2.0 nm gold nanoparticles (AuNP). The patterned monolayer directs bottom-up assembly of a 5 nm/19 nm double pitch AuNP pattern.
两个三苯乙炔衍生物，1OH 和 2，在溶液-石墨（HOPG）界面自组装成图案化单层（ML）。ML 的四分子单元晶格，（1OH1OH22），跨越 19nm，包含相邻的 1OH 分子列，间隔 4.7nm。在 ML 组装后，每个 1OH 分子上的醇基附加一个二硫键，并用于捕获 2.0nm 的金纳米粒子（AuNP）。图案化的单层指导 5nm/19nm 双间距 AuNP 图案的自下而上组装。
