Fig. 1 is the crown ether monomer I, and secondary ammonium salt monomer II and crown ether monomer I and secondary ammonium salt monomer II form the structural representation of supermolecule polymer III by the interaction of hydrogen bond between the Subjective and Objective.Positively charged ion in the secondary ammonium salt monomer II can be by the cavity of crown ether monomer I, and hydrogen bound to nitrogen in the secondary ammonium salt monomer II and the ether chain Sauerstoffatom in the crown ether monomer I form supermolecule polymer III by the interaction of hydrogen bond of Subjective and Objective at this moment.Secondary ammonium salt monomer II and crown ether monomer I have very strong interaction to form supermolecule polymer in organic reagents such as chloroform/acetonitrile, toluene/acetonitrile, chlorobenzene, orthodichlorobenzene.
Fig. 2 is the crown ether monomer I, the supermolecule polymer that I and II form under secondary ammonium salt monomer II and the different solubility is at deuterochloroform and the deuterium accumulation proton magnetic spectrum figure for acetonitrile (volume ratio is 1: 1): a) be the crown ether monomer I, b) secondary ammonium salt monomer II, Deng mole solubility crown ether monomer I and secondary ammonium salt monomer II c) 1mM, d) 2mM, e) 5mM, f) 10mM, g) 25mM, h) 50mM, i) 200mM.Can see with the hydrogen atom of the close methylene radical of ammonium positively charged ion that from proton magnetic spectrum figure tangible displacement is arranged under different solubility.Along with the increase of solubility, the interaction between crown ether monomer I and the secondary ammonium salt monomer II strengthens, and makes chemical shift draw close to 4.80.When solubility reached 10mM, the chemical shift with the hydrogen atom close methylene radical of ammonium root positively charged ion among the proton magnetic spectrum figure remained unchanged substantially, and the form that the supermolecule polymer that solubility forms more than 10mM is described is identical.Therefore, thus proton magnetic spectrum figure proves crown ether monomer I and secondary ammonium salt monomer II very intuitively has very strong interaction to form supermolecule polymer in the mixed solvent of chloroform and acetonitrile.Crown ether monomer I and the interaction strength difference of secondary ammonium salt monomer II in different organic solvents, binding constant changes to some extent, makes the final supermolecule polymer that forms difference to some extent on the form in solution.The crown ether monomer I is identical at the action intensity under solid-state with secondary ammonium salt monomer II, and binding constant is the same, and the form of the supermolecule polymer that obtains is the same.
Fig. 3 is the crown ether monomer I, the differential scanning calorimetric thermogram of the supermolecule polymer III of secondary ammonium salt monomer II and solid state powder.The second-order transition temperature of crown ether monomer I is 8 ℃, and the second-order transition temperature of secondary ammonium salt monomer II is 53 ℃, and the second-order transition temperature of supermolecule polymer III compares with monomer and be greatly improved, and is 110 ℃.And there is not monomeric variation in the spectrogram of supermolecule polymer III, thereby further specify the crown ether monomer I and secondary ammonium salt monomer II has formed supermolecule polymer III by interaction, and second-order transition temperature also is improved largely, and makes supermolecule polymer have good processing characteristics.
Fig. 4 is that the viscosity under the different solubility of supermolecule polymer III changes bilogarithmic graph in chloroform and acetonitrile mixed solvent.Under low solubility, slope of a curve is 0.034, and along with the increase of solubility, slope of a curve becomes 1.758 by 0.034.Under high viscosity, supermolecule polymer III is beneficial to intermolecular self-assembly.The change solubility of slope shows the transformation of supermolecule polymer to single form greatly about 22mM.
Fig. 5 and Fig. 6 are respectively the crown ether monomer I, the film absorption spectrum of the supermolecule polymer III of secondary ammonium salt monomer II and solid state powder and emmission spectrum figure.As can be seen, supermolecule polymer III compares with crown ether monomer I and secondary ammonium salt monomer II, keeps the position of original absorption peak and emission peak basically from absorption spectrum and emmission spectrum figure.The maximum absorption band of spectrogram and maximum emission peak have shown that supermolecule polymer III has possessed the characteristic of blue light material, and then are used as the blue light material of Organic Light Emitting Diode luminescent layer.
Fig. 7 is the mix film emmission spectrum figure of 1% Ir (PPy) 3 of the supermolecule polymer III of solid state powder.From the film emmission spectrum, the triplet of supermolecule polymer III is higher than Ir (PPy) 3 triplet as can be seen, is applied in the phosphorescence luminescent device thereby supermolecule polymer III can be used as the material of main part of Ir (PPy) 3.And then can obtain organic diode device efficiently.
In order further to obtain device efficiently, can increase the conjugate unit of oligopolymer.Also can obtain the device of different colours simultaneously by changing the conjugate unit of oligopolymer.In the monomer that obtains the different colours device, can obtain white light parts by adjusting the content of redgreenblue.Supermolecule polymer white light material has easy-regulating, can repeat to compare with unit molecule white light material.In case study on implementation 2, the function of above-mentioned supermolecule polymer material can be accomplished.
