The spatial arrangement of fluorophor, is conducive to apparent Fluorescence Mechanism and explores potential application.Current L-CPs is in fluorescence probe field
Such as detect shown in terms of the high quick-fried thing molecule of nitro, metal ion important application prospect (Chem.Soc.Rev.2014,
43,5815、Adv.Sci.2016,3,1500434).Wherein, achievement in research be concentrated mainly on transition metal (3d-Zn, Cd), it is dilute
Native (4f-Eu, Tb) and rare earth-transition metal (3d-4f) different metal L-CPs (Coord.Chem.Rev.2014,273,76).
Magnesium metal is inexpensive, nontoxic, in the absence of the light energy losses brought due to d-d transition, and colourless with itself
Bright, strong to the transmitance of light the advantages of, so being especially suitable for constructing the L-CPs lighted based on organic ligand；While magnesium ion is also
There is similar ionic radius and coordination mode with transition metal ions.So, magnesium is combined with transition metal, further with having
The collaboration assembling of machine part, the secondary construction unit of the metal oxygen formed in an assembling process will be more more flexible than single metal changeable, no
Only can be with the novel CPs of construction structure, and the excellent L- of luminescent properties can be constructed by reasonable selection organic light emission part
CPs.However, be currently based on the different metal of magnesium-transition metals CPs research it is less (CrystEngComm 2012,14,4843,
Dalton Trans.2013,42,2294)；And it is used for the different metal base L-CPs of the magnesium-transition metals in fluoroscopic examination field not yet
Report.So, design synthesis magnesium-transition different metal base L-CPs either expands abundant L-CPs structure type, or exploitation
Potential applications of the different metal L-CPs in fluoroscopic examination field all has important researching value and realistic meaning.
