A new class of organometallic liquid‐crystalline rigid‐rod polymers containing thiophene (see Figure) are reported and it is shown how their phase behavior can be tuned through variation of the side groups. The crystallization of the compound shown in the Figure proceeds through a transient lyotropic smectic state, a state hitherto unknown in polymeric organometallic systems magnified image .
