摘要：A novel series of tetrahedrally silicon-centered pyrazole derivatives, including bis(4-(pyrazol-l-yl)phenyl)-dimethylsilane (1), bis(3-(pyrazol-l-yl)phenyl)dimethylsi-lane (2) and tri(4-(pyrazole-l-yl)phenyl)methylsilane (3) have been designed, synthesized and determined by FT-IR, \'H NMR, ~(13)C NMR, ~(29)Si NMR and mass spectroscopy. These compounds are stable in moisture and have high thermal stability. The optical properties reveal that these compounds show a fluorescent emission in the blue-violet region, which could be potentially applied as blue emitters for OLEDs and utilized to construct functional MOFs with luminescent properties.
