Liquid-crystalline functional carbazole and naphthalene platforms

摘要: Two novel families of highly functionalized molecules consisting a central carbazole or naphthalene core carrying actionable acid functions and linked to gallate platforms equipped with three long alkoxy chains have been rationally designed. The presence amide tethers chelating rigid fragments generate new class luminescent mesomorphic materials. Platforms bearing paraffin (n = 12 16) self-organize into columnar liquid crystalline phases in which the columns are arranged according 2D oblique, rectangular hexagonal lattice symmetry as deduced from powder XRD experiments. FT-IR studies confirm that common driving force for aggregation micro-segregation mesophase is due occurrence tight intermolecular H-bonded network. Spectroscopic measurements show these solution solid state. Due synthetic availability cores simplicity by can be graphed, this methodology represents practical alternative production fluorescent
