Derivatives of pyridine and benzoic acid having suitable structures can associate through single hydrogen bonds to form liquid crystalline systems. The “know‐how” was established by systematically varying the substituents on the benzoic acid (see below): weakly electron‐withdrawing substituents are the most efficient for inducing a liquid crystalline state when the substituent on the pyridine ring is an electron donor.
