Two triphenyleneethynylene derivatives, 1^OH and 2, self-assemble a patterned monolayer (ML) at the solution–graphite (HOPG) interface. The four molecule unit cell of the ML, (1^OH1^OH22), spans 19 nm and contains adjacent columns of 1^OH molecules spaced by 4.7 nm. Following ML assembly, a disulfide is appended to the alcohol group on each 1^OH 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.

HOPG上的纳米颗粒阵列的反应性两组分单层模板自下而上组装†

两种三亚苯基亚乙炔基衍生物1 ^OH和2在溶液-石墨（HOPG）界面上自组装图案化单层（ML）。ML的四分子晶胞（1 ^OH 1 ^OH 22）跨度19 nm，并包含相邻的1 ^OH分子，相隔4.7 nm的列。ML组装后，将二硫键附加到每个1 ^OH分子上的醇基上，并用于捕获2.0 nm金纳米颗粒（AuNP）。图案化的单层指导5 nm / 19 nm双节距AuNP图案的自下而上组装。
