Featured Liquid Crystal Picture Art of the Month
Colorful flower petals
The micrograph is obtained in a chiral bent-core liquid crystal filled in a planar geometry under the polarizing optical microscope in crossed polarized state. The different colors correspond to the different twisted states of the twist grain boundary phase (TGBA).

This texture corresponds to the mesophase formed by a chiral bent-core liquid crystal compound. It represents characteristic defects of one of the chiral mesophases, the twist grain boundary A (TGBA), where different color domains arise due to different twist states. The microphotography is highly attractive from an aesthetic and artistic point of view, very suggestive and somehow shows the other side of sensory perception - "realities and interests” - that was highlighted on the occasion of June 2022 ILCS liquid crystal picture.
