The design and preparation of liquid crystalline (LC) block copolymers by use of azo‐macroinitiators are outlined. This approach is very versatile and makes it possible to realize diverse architectures of block copolymers, including non‐LC/side‐chain, non‐LC/main‐chain and side‐chain/main‐chain block copolymers. The different blocks were phase separated and underwent their individual phase transitions. In side‐chain/main‐chain block copolymers different LC mesophases coexisted in equilibrium.
