A Chemical structures of the repeating units in the polyimides. B WAXD profiles of the PI films. C 3D model of the repeating unit in an all-trans conformation, showing the calculated periodic repeat length. D Proposed mesogen stacking arrangement inferred from the WAXD measurements. E 3D models of the LC-PIs based on the WAXD profiles. The bonds are color-coded by atom type, as shown in the top snapshot of the PI-B6 model
