The present invention relates to a lyotropic chromonic liquid crystal composition, a method for manufacturing a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention includes chromonic liquid crystal compounds and monomers each having opposing acid-base properties. Use of the lyotropic chromonic liquid crystal composition in the formation of optical films leads to improvements in electrical and optical properties such as mechanical strength, an insulating characteristic and a refractive index.

Green Synthesis of Polycyclic Benzimidazole Derivatives and Organic Semiconductors
Polycyclic benzimidazole derivatives, an important class of compounds in organic electronics and photovoltaics, were prepared using a solvent-free “green” process based on heating carboxylic acid anhydrides and arylene diamines in the presence of zinc acetate in the solid state. Products were isolated and purified directly by train sublimation of the crude reaction mixtures. The reaction conditions
