Kurzfassung englisch:
Inorganic-organic hybrid polymers based on 3-(3-pyridyl)-5-(4-pyridyl)-1,2,4-triazole (3,4-Hbpt) ligand were synthesized and subsequently characterized by single-crystal X-ray diffraction, FT-IR spectra, ele-mental analyses, thermogravimetric (TG) analyses and PXRD. The X-ray diffraction analyses revealed that the complexes [Zn(3,4-Hbpt)Cl2] and [Zn(3,4-Hbpt)Br2] possess a 1-D helical chain structure con-structed of the 3,4-Hbpt ligands connecting the zinc cations. The [Zn(3,4-bpt)(OAc)] complex demon-strates a 2D sheet structure bridged by tridentate 3,4-bpt-anions. All compounds exhibit substantial ther-mal stability and show photo-fluorescent properties that result from the ligand π-π* transition. Ultravio-let-to-visible tuneable emission for two of the complexes is observed.
