Hydrogen bonding regulation-oriented design of pyridine sulfonate as a promising UV birefringent crystal characterized by enhanced structural anisotropy.
Ontology highlight
ABSTRACT: Birefringent materials, capable of manipulating light polarization, are pivotal in advanced optical technologies. Traditionally, the development of such materials has predominantly focused on purely inorganic compounds, which often exhibit limited birefringence. Herein, we present a new 3-pyridinesulfonate birefringent crystal, Ca(3-C5H4NSO3)2·4H2O, synthesized via a hydrogen-bonded regulation strategy designed to enhance the coplanarity of [3-pySO3] groups. As expected, Ca(3-C5H4NSO3)2·4H2O demonstrates a notably large birefringence of 0.286@532 nm, exceeding that of most commercially available birefringent crystals. Furthermore, this compound demonstrates outsta
