An absorbing study : The displayed quaterrylenebis(dicarboximide) was imparted with lyotropic liquid‐crystalline properties by molecular design. The ability of the molecule to self‐organize in solution allows for the subsequent control of its orientation in thin solid films. Induced orientation of the liquid‐crystalline domains of the molecule under a shearing force results in highly anisotropically ordered films that serve as dichroic polarizers of light at wavelengths greater than 600 nm.
