Description

The hair of the polyhedral oligomeric silsesquioxane rare earth compounding of function containing esters of acrylic acid The synthetic method of light polyacrylic materials
Technical field
The present invention relates to a kind of the luminous of the polyhedral oligomeric of function containing esters of acrylic acid silsesquioxane rare earth compounding The synthetic method of polyacrylic materials, belong to rare earth high polymer composite functional material field.
Background technology
Rare earth luminescent material such as is widely used in illuminating, show and detect at the field, forms very big industrial production and disappears Take market scale, and just expanded to other emerging technologies (such as solid-state dye laser, false proof) field rapidly.Due to containing dilute The high-molecular luminous material of native complex has the luminescent properties of rare earth ion concurrently and the characteristics of stabilizing polymer is good, easy processing, Extensive concern is caused.Its research method is basically divided into two kinds:(1) rare earth small molecule is directly mixed to get doping with macromolecule The Luminescence of Rare Earth Polymer Complex of type;(2) rare earth compounding of polymerisation can be occurred by first being synthesized by the method for chemical bonding Monomer, then it polymerize to obtain rare earth high polymer copolymer fluorescent material, or rare earth ion and macromolecule with other organic monomers Ligand groups such as carboxyl, sulfonic group react obtained Luminescence of Rare Earth Polymer Complex on chain.The most frequently used method is by rare earth Compound is distributed in monomer or polymer as dopant, is made with rare earth high polymer fluorescent polymer existing for doping way, Its preparation technology is simpler, and production cost is relatively low, is widely used in many aspects.But because rare earth compounding is in polymeric matrix It is middle the shortcomings of dispersiveness is bad, is easily separated with matrix to be present, thus cause doping type rare earth high polymer material stability Difference, generation concentration is quenched between fluorescence molecule, and fluorescence intensity reduces, and fluorescence lifetime declines.Chemical bond mould assembly rare earth high polymer can Overcome the rare earth compounding that doping type rare earth high polymer is often presented and resin affinity poor, material transparent and poor mechanical property etc. Shortcoming, the rare earth high polymer functional material for the wide content of rare earth of acquisition, high transmission rate provide an effective way, caused The great interest of people.
In rare earth compounding, rare earth organic complex is easy to produce solvation effect because itself photo and thermal stability is poor Cause fluorescent quenching, and limit its use range.New hybrid inorganic-organic rare earth compounding can substantially improve this Situation.In recent years, polyhedral oligomeric silsesquioxane (abbreviation POSS) is because of its excellent heat endurance and easily designed functionalization The characteristics of caused the great interest of people.It is coordinated to form POSS base rare earth compoundings using rare earth compound and POSS, then It is copolymerized with polymer monomer, wide content of rare earth, the rare earth high polymer composite functional material of high transmission rate can be prepared.
Chinese patent document CN104193860A (application numbers:201410403041.5) disclose a kind of multiaspect containing rare earth The synthetic method of body oligomeric silsesquioxane based high molecular composite luminescent material, first will will be through organic using Coordinative Chemistry principle The method and the first ligand rare earth ion that the polyhedral oligomeric silsesquioxane of ligand-modified cage structure passes through collosol and gel Coordination, being then re-introduced into can be coordinated with the polymethyl methacrylate of rare-earth ion coordination as Ligands, final Polyhedral oligomeric silsesquioxane base to the cage structure containing rare earth with good fluorescence property and heat endurance is high Molecule composite luminescent material.But on the one hand the above method needs first with organic ligands such as acetylacetone,2,4-pentanedione or salicylic acids to be matched somebody with somebody Position, preparation process are complicated;On the other hand, the polyhedral oligomeric silsesquioxane of the cage structure used is the monoamine of cage structure The sulfydryl polyhedral oligomeric silsesquioxane of polyhedral oligomeric silsesquioxane or cage structure, it is impossible to direct with rare earth element Coordination, nor copolyreaction can be carried out.
