Silica‐based hybrid molecularly imprinted polymer (MIP) monoliths with good chiral recognition ability are synthesized (see figure) using a novel method, a room temperature ionic liquid (RTIL)‐mediated, non‐hydrolytic sol–gel technique. The approach avoids the cracking and shrinking of the bed during drying, which is commonly associated with conventional sol–gel processing, overcomes the shortcomings associated with conventional organic‐polymer‐based MIP matrices, and offers improved selectivity.
