Solid-State Chemistry of Cyanine-Type Dyes and the Effect of Two Novel Counterions on Their Crystal Properties

摘要: Organic dyes undergo a variety of solid-state chemical processes, including intra- and intermolecular reactions, gas-solid polymorphic transformations. The properties dye solids are markedly affected by this chemistry. This paper reviews solid state chemistry from the literature reports in detail two novel cyanine salts whose controlled nature their counterions. In cyanine-oxonol salts, oxonol counterion is large planar which forms crystalline aggregates with ions. There multiplicity these mixed reflecting multiple favorable aggregate geometries. cyanine-borate reactions. either single crystals or dispersions latter polymer binders, alkyl transfer anion to chromophore can be induced thermally photochemically.
