Magnolol and honokiol included green emissive terbium sol–gel materials and their recognition behaviors
- 141 Downloads
Magnolol and honokiol as pharmaceutical ligands have been introduced into terbium complex systems for the first time and two hybrid organic–inorganic materials were successfully prepared. Both of them can sensitize terbium characteristic green emission effectively based on intra-molecular energy transfer channel. Moreover, they selectively recognized Cu2+ and Fe3+ through luminescence quenching effects. The photophysical properties and morphological structures were extensively investigated.
