Amphiphilicity of Tetraazaporphyrins Containing Four Terminal Carboxylic Acid and Four Alkyl Groups Promotes Face-On Orientation in Langmuir Films

Author(s): Alinia Z; Abdulhamied E; Selmani S; Miclette Lamarche R; Eichhorn SH; DeWolf CE;

Control over the orientation of polycyclic aromatic dyes in thin films is paramount to tailoring their optical, electronic, and mechanical properties. Their supramolecular assembly in films is tuned here by converting the macrocyclic dyes to large amphiphiles. Two octaalkythio-substituted tetraazaporphyrins (TAPs) with one 5-carboxypentyl and one pentyl o ...

Core charge of imidazolium annulated triphenylene derivatives induces discotic columnar mesomorphism

Author(s): Chen S; Taing H; Ahmida M; He HY; Carr A; Muchall HM; Eichhorn SH;

Thermotropic ionic liquid crystals have remained a relatively little studied group of materials despite their many potential applications as anisotropic ionic liquids and charge (ion and electron/hole) transporting materials. Particularly rare are core charged discotic liquid crystals because their synthesis is usually more involved, and their molecular d ...
