Buttered side up : A one nanometer thick membrane with different functional groups on each side was fabricated from self‐assembled monolayers of aromatic molecules. The amino side of this Janus membrane was modified with tetramethylrhodamine (TMR) fluorescent dye, and the thiol side with ATTO647N (see picture). The functionalization and functionality of the nanomembrane were demonstrated by X‐ray photoelectron spectroscopy and fluorescence microscopy.
