Synthesis and application of dinuclear ring metal platinum (II) complex near-infrared electrophosphorescent material containing different conjugated bridges

The invention discloses a dinuclear ring metal platinum (II) complex near-infrared electrophosphorescent material containing different conjugated bridges, and application of the electrophosphorescent material to an organic electroluminescent diode. The dinuclear ring metal platinum complex near-infrared electrophosphorescent material uses different conjugated rigid structures (benzene, 1,4-difluorobenzene, carbazole, fluorene and pyrene) as luminous kernel donor (D) units, and uses nitrogen-containing dentate conjugate ligands (isoquinoline, anthraquinoline and phenanthridine) as receptor (A) units for building the ring metal platinum complex near-infrared electrophosphorescent material using A-D-A structure as a main ligand, using 2,2,6,6-tetramethyl-3,5-heptadione as an auxiliary ligand and using platinum ions. The organic electrophosphorescent luminous device is prepared by using the near-infrared electrophosphorescent material as a luminous layer doping agent and using m-MTDATA:CBP as a body material. The device is a near-infrared electrophosphorescent luminous device with the maximum emitting peak being 709nm, the outer quantum efficiency being 3.97 percent and the maximum radiation degree being 2354nW.Sr<-1>.cm<-2>.

Assembled early-detached building template system and setup method thereof

The invention is applicable to the technical field of building construction and provides an assembled early-detached building template system and a setup method thereof. In the template system, a first standard internal-wall template is close to the internal-corner position of a building structure, and a first non-standard external-wall template is close to the external-corner position of the building structure, so that a first vertical is closer to a wire drawing rod rather than the building structure, and stress of the template at the corner position of the building structure is improved. Wire drawing rod holes are arranged in second standard internal and external wallboards, the horizontal distance and the height distance of the wire drawing rod group are fixed, standardized and serialized, and processing difficulty and cost of templates are lowered. Meanwhile, hole positions have no need to be repeatedly changed, turnover rate of the templates is increased, service lives of the templates are prolonged and cost is reduced. With the bottom angle plate, the first vertical internal-corner template, the second vertical internal-corner template and the inner wallboard, structural rigidity of the template system is enhanced, the horizontal-plane template correcting procedure of the inner wallboard is simplified in advance, and setup efficiency of the template system is improved.

Fused heterocyclic aromatic hydrocarbon derivative as well as preparation and application thereof

The invention belongs to the technical field of photoelectric material application, and particularly relates to a fused heterocyclic aromatic hydrocarbon derivative, and preparation and application thereof. According to the material, a benzoheterocycle is bridged at an aza site of phenothiazine oxygen; a conjugate site of the benzoheterocycle is further modified to realize compound rigid structureregulation and control and conjugation prolonging, so that the material thermal stability is effectively improved, the light extraction efficiency of devices is greatly improved due to a relatively high refractive index and a relatively low extinction coefficient of the material in a visible light region, and the material is an excellent covering layer material; the fused heterocyclic aromatic hydrocarbon derivative has a structural formula shown as a formula (I), wherein X is selected from O, S or O = S = O; wherein R1, R2, R3 and R4 are independently selected from alkyl, aryl substituted orunsubstituted by a substituent group and having 6-30 ring-forming carbon atoms, heteroaryl substituted or unsubstituted by a substituent group and having 3-30 ring-forming atoms, and triarylamino substituted or unsubstituted by a substituent group.

A kind of preparation method and application of aluminum tanning agent complex that can be polymerized in skin collagen

The invention discloses a preparation method and application of an aluminum tanning agent complex capable of polymerizing in leather collagen, and belongs to the technical field of leather processing.The preparation method comprises the steps that water-soluble polymers mainly comprising non-volatile unsaturated monomers, such as propylene sulfonic acids, are used as raw materials to prepare thealuminum tanning agent capable of polymerizing in the leather collagen in leather, and then the complex unsaturated monomers in the aluminum tanning agent are subjected to polymerization reaction in the leather collagen by using an initiator to form polymers, and transverse crosslinking or multi-point hydrogen bonds is / are formed, so that the shrinkage temperature of the leather collagen can be upto 80 DEG C. The polymers can be generated in the leather collagen, so that the absorption rate of aluminum tannin is improved, the washing resistance of the aluminum tanning agent in the leather isimproved, and the aluminum tanning agent can be used in a leather tanning agent instead of a chrome tanning agent. According to the preparation method and the application of the aluminum tanning agentcomplex capable of polymerizing in the leather collagen, the high quality requirement of the leather is met, and the cleaning technical requirement of the leather industry is met.
