Specific implementation mode
Embodiment：
(1) 0.1 mM is weighed（0.0313 gram）4'- phenyl -2,2 ':6 ', 2 ' '-terpyridyl is dissolved in 6 milliliters of dichloromethanes
Obtained solution in alkane moves into solution in the reaction kettle that volume is 25 milliliters.
(2) 0.1 mM is weighed（0.0452 gram）Six nitric hydrate terbiums, which are dissolved in 2 milliliters of acetonitriles, is made six hydration nitre
Six nitric hydrate terbium solution are added in the reaction kettle of step (1), reaction kettle are then placed in electric heating forced air drying by sour terbium solution
In case, isothermal reaction 48 hours, are finally cooled to room temperature at 80 DEG C, obtain white needle-like crystals, as phenyl -2 4'-, and 2 ':
6 ', 2 ' '-terpyridyl nitric acid terbium coordination compound, phenyl -2 4'-, 2 ':The structure of 6 ', 2 ' '-terpyridyl nitric acid terbium coordination compound
For：
The 4'- phenyl -2,2 ':6 ', 2 ' '-terpyridyl nitric acid terbium coordination compound belongs to rhombic system, and space group isPbca,
In basic structural unit include a terbium ion, phenyl -2 4'-, 2 ':6 ', 2 ' '-terpyridyl molecule, three nitrate anions
Ion and a hydrone.Center Tb (III) ion respectively with 4'- phenyl -2,2 ':The three of 6 ', 2 ' '-terpyridyl neutral ligand
A nitrogen-atoms（N1、N2、N3）It is coordinated in the form of three teeth chelate, with three nitrate ions（O1、O3；O4、O6；O7、O9）With
The form coordination of bidentate chelating, with hydrone（O10）Coordination, forms double cap dodecahedron configurations of ten coordinations.Tb-O bond distance
Be 2.423 ~ 2.668, Tb-N bond distances it is 2.503 ~ 2.546.
At room temperature to complex and ligand 4'- phenyl -2,2 ':6 ', 2 ' '-terpyridyl has carried out solid state fluorescence test,
2.5/2.5 nm of slit width.From Figure 2 it can be seen that phenyl -2 ligand 4'-, 2 ':6 ', 2 ' '-terpyridyl itself possesses stronger
Fluorescence, excitation wavelength are 280 nm, and launch wavelength is 365 nm.Maximum emission wavelength herein substantially belongs to n → π *
Or the transition of π → π *.Cause this reason is that due in the pyridine ring in ligand structure C=N double bonds can form the big pi bond of conjugation, π
Electron mobility is big, so being easy transmitting fluorescence.Complex Tb (ptpy) (NO3)3(H2O) swashed under 325 nm excitation wavelengths
Hair shows green emitting.Peak at 492 nm can be attributed to Tb3+Feature5D4→7F6Transition, the peak at 546 nm can belong to
For Tb3+Feature5D4→7F5Transition, the peak at 586 nm is attributed to Tb3+Feature5D4→7F4Transition, at 624 nm
Peak is attributed to Tb3+Feature5D4→7F3Transition, it can be seen that complex sends out stronger characteristic fluorescence.In addition,
Stronger emission peak is not observed at 365nm, complex fluorescent emission peak is extremely weak compared with ligand, this illustrates phenyl -2 ligand 4'-,
2′:6 ', 2 ' '-terpyridyl is to Tb3+It is luminous be an effective sensitizer.
