The synthesis of C3-symmetrical tristriazolotriazines with conjugated arms and lateral alkoxy side chains was performed by a threefold condensation of cyanuric chloride with tetrazoles. Conjugated π segments include phenyl, tolane, and its phenylethynyl-elongated homologue. Disclike and a dendritic molecule have been obtained, and two compounds with a 3,4,5-tris(octyloxy) substitution form broad thermotropic
Tristriazolotriazines (TTTs) with a threefold alkoxyphenyl substitution were prepared and studied by DSC, polarized optical microscopy (POM) and X-ray scattering. Six pentyloxy chains are sufficient to induce liquid-crystalline behavior in these star-shaped compounds. Thermotropicproperties of TTTs with varying substitution patterns and a periphery of linear chains of different lengths, branching
core and a periphery of six to nine alkoxy chains are synthesized via Huisgen reaction. DSC, POM, and TGA give information about the thermal properties of these discotic liquid crystals, XRD enlightens the structures of the very broad mesophases The efficient fluorescence of these discs is positively solvatochromic and strongly influenced by aggregation.
