Organic π-conjugated units as versatile building blocks for high-performance birefringent crystals

Research on high-performance birefringent crystals with birefringence values greater than 0.3 has grown rapidly in recent years. These materials hold great promise for enabling the compactness and miniaturization of optical components that manipulate the phase and polairization of light. Crystals based on organic π-conjugated units frequently exhibit birefringence values exceeding 0.3, establishing them as effective building blocks for next-generation birefringent materials. This work highlights recent progress in the development of birefringent crystals derived from organic π-conjugated units. We emphasize the pivotal role of these functional building blocks in crystal design and materials discovery, and review representative studies that report high-performance birefringent crystals. The article concludes with a discussion of current challenges and outlines future research directions in this emerging field.
