We present that conjugated polymer bearing chiral side chains self-assemble into solid microspheres with atwisted bipolar interior. The single microsphere exhibits distinct angularly anisotropic CPL with glum up to ∼0.5 in the equatorial plane, which is 2.5-fold greater than that along the polar axis.

Circular dichroism in layer-by-layer chiral photonic crystals is numerically studied. Stop gaps for circularpolarization in the stacking direction can be modified by tuning the in-plane period, which is new compared
to one-dimensional Bragg structures.
