Novel salicyloylhydrazone derivatives and corresponding terbium(III) complexes: Synthesis and properties research

Four novel salicyloylhydrazone derivatives and their terbium(III) complexes were synthesized and characterized. The thermal analysis results showed that the terbium(III) complexes possessed good thermal stability. The fluorescence research results showed that the terbium(III) complex substituted by phenyl possessed the best fluorescence intensity among them, and its fluorescence quantum yield was also the highest. The exploration of the electrochemical properties indicated that the introduction of electron-donating groups to the ligand can increase the highest occupied molecular orbital (HOMO) energy levels and decrease the oxidation potential of the corresponding terbium(III) complexes. The introduction of electron-withdrawing groups to the ligand can reduce their HOMO energy levels and increase their oxidation potential. The results showed that the terbium(III) complexes are good candidates for luminescent material.

Selectively catalytic epoxidation of α-pinene with dry air over the composite catalysts of Co-MOR(L) with Schiff-base ligands

Twelve bi-/tridentate Schiff-base ligands (L1-L12) have been designed, synthesized and coordinated with ion-exchanged Co-MOR (Mordenite) forming a series of Co-MOR(L) composite catalysts, for which various analyzes and characterizations are conducted. Selectively catalytic epoxidation of α-pinene with dry air over Co-MOR(L) catalysts has been carried out, where uses TBHP in small amounts as the initiator. Among these Co-MOR(L) catalysts, Co-MOR(L8) exhibits the best activity for the titled reaction to obtain 85.8 mol% conversion and 90.8% selectivity of epoxide. Some factors such as the structure of ligands, the oxidants, the solvents, the catalyst amount, the reaction temperature and time play important roles in controlling the epoxidation. The recyclable stability of the Co-MOR(L8) catalyst is confirmed. The studies on the electrochemical behaviors of Co species in Co-MOR(L8) reveal the importance of reversible change between Co oxidation states for the epoxidation.
