We demonstrate an ew approach to pattern functional organic molecules with atemplate of foams,and achieve ar esolution of sub 100 nm. The bubble-assisted assembly (BAA) process is consisted of two periods,i ncluding bubble evolution and molecular assembly,which are dominated by the Laplace pressure and molecular interactions,r espectively. Using TPPS (meso-tetra(4-sulfonatophenyl) porphyrin), we systematically investigate the patterns and assembly behaviour in the bubble system with as eries of characterizations,w hich show good uniformity in nanoscale resolution. Theoretical simulations reveal that TPPSsJ -aggregates contribute to the ordered construction of molecular patterns.F inally,w ep ropose an empirical rule for molecular patterning approach, that the surfactant and functional molecules should have the same type of charge in at wo-component system. This approach exhibits promising feasibility to assemble molecular patterns at nanoscale resolution for micro/nano functional devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
