LIGHT-POLARIZING PARTICLES AND THESE COMPREHENSIVE LIQUID SUSPENSIONS AND LIGHT MODULATORS

摘要

Polyhalide light-polarizing particles prepared by the process comprising reacting in a suitable liquid (i) elemental molecular iodine, (ii) an inorganic halide, with (iii) a substantially rigid polycyclic precursor compound, wherein: a. the polycyclic precursor compound has two cyclic structures linked together via an aromatic or heteroaromatic group; b. the three-dimensional structure of the polycyclic precursor compound has a cavity defined by the two cyclic structures and only one opening into the cavity; and c. polar groups are provided in the outside of the polycyclic precursor compound; and d. one of more chelating group or groups are provided inside the cavity of the precursor group for chelating hydrogen or metal ions.
