A Selective Biomimetic Tweezer for Noradrenaline

Abstract
The new highly preorganized tweezer molecule 1 binds noradrenaline in polar solvents with unprecedented specificity. It uses a biomimetic recognition pattern and rejects almost all other neurotransmitters. LB experiments on a film balance reflect the same selectivity if 1 is incorporated into a stearic acid monolayer.
