## Abstract An artificial dipeptide receptor (**1**) was designed and observed to bind the deprotonated dipeptide AcβDβAlaβDβAlaβOH in buffered water with __K__ = 33β100βm^β1^, whereas other dipeptides such as AcβGlyβGlyβOH or AcβDβValβDβValβOH were bound less efficiently, by factors of more than 1
