Synthesis and Properties of 〖WTHX〗tert〖WTHZ〗Butylphenyl Carbazole Derivatives with High Thermal Stabilities and High Fluorescent Quantum Yields[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(6):68-73.DOI:
-butylphenyl carbazole derivatives were synthesized by WittigHorner reactions. The chemical structures of the derivatives were determined by
1
H NMR
IR
MS and EA analyses
and their properties were investigated by UV
PL
TGA
DSC and CV methods. The results showed that ① the synthesized compounds could emit strong fluorescence either in solutions or in solid states and their fluorescent quantum yields ranged from 77% to 54%; ② the compounds possessed high thermal stabilities
and their thermal decomposition temperatures and glass transition temperatures were higher than 470℃ and 220 ℃
respectively;③ their maximum absorption and fluorescence emission wavelengths were related to the linking groups.
