Abstract Ultrathin membranes with subnanometerpores enabling molecular size-selective separation were generated on surfaces via electron-induced cross-linking of self-assembled monolayers (SAMs). The evolution of p-terphenylthiol (TPT) SAMs on Au(111) surfaces into cross-linked monolayers was observed
simulations, we propose that these voids may correspond to free volumes inside a cross-linked monolayer.

Electron-induced chemistry plays an essential
supports [31][32], mechanical resonators [33], and dielectrics in nanocapacitors [34][35]. It has been shown that CNMs possess subnanometerpores, which can block the passage of most molecules and ions, but let water and helium pass through, enabling the use of CNMs in molecular filtration and ion
