Two families of ester‐type banana monomers are presented, 1,3‐phenylene bis{4‐[4′‐(10‐undecenyloxy)benzoyloxy]benzoate}s and 1,3‐phenylene bis{[4′‐(10‐undecenyloxy)]‐1,1′‐biphenyl‐4‐carboxylate}s, in which the nature of the substituents on the central phenyl ring and the side arms was varied. The mesophase behavior of the monomers, including B 2 and B 7 phases, was correlated with their chemical structure and was compared with that of analogous azomethine‐type banana mesogens. It is also shown that the banana monomers can be incorporated into new architectures of liquid crystal polymers.
