Abstract
The invention provides a preparation method for a coordination compound with a reversible phase change dynamic single molecule. The preparation method comprises the following steps: using phenanthroline and methylbenzoic acid ligand as the raw materials to coordinate with rear earth to obtain a double-core rear earth composite [Dy2 (phen) 2 (L) 6].(H2O) 0.5 (C2H5OH); roasting the double-core rear earth complex [Dy2 (phen) 2 (L) 6].(H2O) 0.5 (C2H5OH) at high temperature to obtain a solvent-free complex [Dy2 (phen) 2 (L) 6]; dipping the solvent-free complex [Dy2 (phen) 2 (L) 6] into water to obtain the complex [Dy2 (phen) 2 (L) 6].(H2O) 0.5 (C2H5OH). The preparation method for the complex with the reversible phase change dynamic single molecule is to carry out simple roasting process to obtain a magnet with novel reversible phase change dynamic single molecule; the reversible phase change is convenient and stable in operation, has high repeatability and has good regulating effect on the magnetic performance of the single molecule.
Description
Technical field
The invention belongs to material science, particularly a kind of preparation method with the dynamic single molecular magnets title complex of reversible transformation.
Background technology
Single molecular magnets (SMM) is the branch of an important nanoscale of molecule-based magnetic material; Can be as each molecule of single molecular magnets as conventional magnet as a magnetic functional unit independently; Rather than lean on the long-range order and the interaction of intermolecular arrangement to come exhibit magnetic properties; This will make it become to be hopeful to process molecular device most, thereby reach the molecule magneticsubstance of practical application, have broad application prospects in fields such as information storage and quantum computers.
Dynamically single molecular magnets is one type of special magnetic phenomenon, and it can realize the transformation from a unit molecule magnetic to another one unit molecule magnetic phase with the change of Externality, thereby might realize the energy barrier regulation and control of single molecular magnets fully.In view of the above, this special magnetic behavior that dynamic single molecular magnets shows, making it have broad prospect of application at aspects such as molecular switch, molecular device, molecule sensing and special magneticsubstances becomes possibility.And at present, relevant both at home and abroad research in this respect still is in the blank stage, therefore has very big researching value.
Theoretical investigation shows that high-spin ground state (S) and significant negative anisotropy (D) they are 2 indispensable key elements of single molecular magnets, and the two combination will produce the energy barrier of spin-flip, and this energy barrier and information storage and quantum calculation height correlation.The energy barrier of single molecular magnets spin-flip depends primarily on and revolves rail coupled intensity, can't be by optimizing S respectively and D realizes.Therefore, utilize the single electron number many and have the rare earth ion that revolves the rail coupling by force and prepare high energy barrier single molecular magnets and will get twice the result with half the effort.But; Because the 4f electronics receives the shielding of 5s and 5p electronics in the rare earth ion; Be difficult to improve the intensity of interionic magnetic interaction and the phenomenon that rare earth ion ubiquity specific magnetising moment quantum tunnelling (QTM) effect causes the magneticanisotropy energy barrier to reduce, the rare earth single molecular magnets that therefore obtains high energy barrier also has certain difficulty.
Summary of the invention
The object of the invention just provides that a kind of reversible transformation is easy to operate, stable, repeatability is strong has the dynamic single molecular magnets title complex of a reversible transformation preparation method.
Of the present invention have the dynamic single molecular magnets title complex of a reversible transformation preparation method, is to be the double-core rare earth compounding [Dy that raw material and rare earth coordination obtain with phenanthroline and o-toluic acid part
