A columnar molecular glass at high temperature Fabrícia Nunes da Silva, Arthur Felipe Zito Santos, Taise Matte Manhabosco, Bruna Bueno Postacchini, Thiago Cazati, et al. Journal of Materials Chemistry C, 2026 We prepared two triphenyltriazines decorated with three phenyltriazolyl and three tolanyl systems; only the phenyltriazolyl derivative formed a blue-emissive columnar glass mesophase, promising for anisotropic optoelectronic layers.
Columnar liquid crystal as alignable host for perylene-based emitters Feik Amil de Campos, Carlos H. Stadtlober, Lorenzo C. Serra, Arthur Felipe Zito Santos, Thiago Cazati, et al. Physical Chemistry Chemical Physics, 2025 FRET from the liquid crystal host improves the PLQY of the liquid crystal guest due to host excitation.
Charge carrier transport in perylene-based and pyrene-based columnar liquid crystals Alessandro L Alves, Simone V Bernardino, Carlos H Stadtlober, Edivandro Girotto, Giliandro Farias, et al. Beilstein Journal of Organic Chemistry, 2023 Electron and hole transport characteristics were evaluated for perylene-based and pyrene-based compounds using electron-only and hole-only devices. The perylene presented a columnar hexagonal liquid crystal phase at room temperature with strong molecular π-stacking inside the columns. The pyrene crystallizes bellow 166 °C, preserving the close-packed columnar rectangular structure of the mesophase. Photophysical analysis and numerical calculations assisted the interpretation of positive and negative charge carrier mobilities obtained from fitting the space charge limited regime of current vs voltage curves. The pyrene-based material demonstrated an electron mobility two orders of magnitude higher than the perylene one, indicating the potential of this class of materials as electron transporting layer.
