Designed Metal-Free Quasi-1D Crystals with Giant Birefringence.

ABSTRACT: Birefringence, a vital property of anisotropic crystals, is indispensable for advanced optical technologies. Quasi-1D structures, with their inherent structural anisotropy, offer fertile ground for discovering materials with exceptional optical anisotropy. In this work, we report four metal-free quasi-1D crystals-(C₅H₆NO)⁺(NO₃)^-(4HPN), (C₅H₆NO)⁺(HC₂O₄)^-(4HPO), (C₄N₃H₆)⁺(NO₃)^-(2APMN), and (C₄N₃H₆)⁺(HC₂O₄)^-·H₂O (2APMO)-designed to feature pseudo-chain structures and grown as centimeter-scale crystals via a facile aqueous-
