Síntese do primeiro cristal líquido iônico derivado da tristriazolotriazina
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em QuímicaUTFPR, 2017-09-15)
This work describes the synthesis, characterization and the studies of the thermal and organizational properties of a new ionic liquid-crystalline material derived from tristriazolotriazine (TTT). Initially, the TTT was ...
Estudo sistemático sobre a inserção de acilhidrazonas em cristais líquidos policatenares
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em QuímicaUTFPR, 2019-06-19)
Liquid Crystals (LC) are materials which combine characteristics from solid state (organization and anisotropy) and liquid state (fluidity). Such materials have a great technological interest due to their unique properties, ...
Síntese e caracterização de cristais líquidos curvados derivados da dibenzalacetona
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em QuímicaUTFPR, 2021-12-06)
Liquid crystals (Lcs) are substances that show simultaneously fluidity- characteristic of liquid state – and molecular organization and anisotropy – characteristic of the solid state. They are widely investigated both in ...
Cristal líquido iônico dimérico não simétrico com propriedades luminescentes
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em QuímicaUTFPR, 2019-06-18)
With increasing in consumption and manufacturing of electronic devices, there has been a growing interest in the production of materials that are cheaper, easier to synthesize and with reduced power consumption compared ...
