Luminescent element material and luminescent element comprising the same

The light emitting device of the present invention relates to a light emitting device which is characterized in that it is a device with an emissive substance present between an anode and cathode, and which emits light by means of electrical energy, and said device has a least one type of compound denoted by (a) to (d) below. (a) A compound having a plurality of 1,7-phenanthroline skeletal structures (b) A benzoquinoline derivative (c) A spiro compound represented by general formula (1) A1 and A2 are each selected from single bonds, substituted or unsubstituted alkyl chains, ether chains, thioether chains, ketone chains and substituted or unsubstituted amino chains. However, A1<> A2. Z represents carbon or silicon. R1 to R16 are each selected from hydrogen, alkyl group, cycloalkyl group, aralkyl group, alkenyl group, cycloalkenyl group, alkynyl group, hydroxyl group, mercapto group, alkoxy group, alkylthio group, aryl ether group, aryl thioether group, aryl group, heterocyclic group, halogen, haloalkane, haloalkene, haloalkyne, cyano group, aldehyde group, carbonyl group, carboxyl group, ester group, carbamoyl group, amino group, nitro group, silyl group, siloxanyl group and a cyclic structure formed with an adjacent substituent. (d) A tetraphenylmethane derivative represented by general formula (2) R17 to R36 are each selected from hydrogen, alkyl group, cycloalkyl group, aralkyl group, alkenyl group, cycloalkenyl group, alkynyl group, hydroxyl group, mercapto group, alkoxy group, alkylthio group, aryl ether group, aryl thioether group, aryl group, heterocyclic group, halogen, haloalkane, haloalkene, haloalkyne, cyano group, aldehyde group, carbonyl group, carboxyl group, ester group, carbamoyl group, amino group, nitro group, silyl group, siloxanyl group and a cyclic structure formed with an adjacent substituent. However, at least one of R17 to R36 is selected from substituents represented by general formula (3). -X-Ar (3) X is a single bond or is selected from the following, and Ar denotes a condensed aromatic ring or heteroaromatic ring. In the case where X is phosphorus oxide, then Ar represents an aromatic hydrocarbon or heteroaromatic ring. n is an natural number.

Preparation method and application of anti-pollution hydrophilic separating membrane

ActiveCN103480278AReduce dosageMeet the needs of hydrophilic immobilizationSemi-permeable membranesMembrane permeabilizationMicrofiltration membrane
The invention discloses a preparation method and an application of an anti-pollution hydrophilic separating membrane. The preparation method is characterized in that a pyrocatechol derivative is used as an accelerant and a curing agent between a separating membrane material and a hydrophilic material, when blending casting film liquid of the separating membrane is prepared, the pyrocatechol derivative is added to blending liquid of the separating membrane material and the hydrophilic material, and the pyrocatechol derivative is subjected to polymerization cross-linking in a phase conversion process of the membrane preparation, so that the effect of fixing the hydrophilic material is achieved. The preparation method of the anti-pollution hydrophilic separating membrane has strong universality and is suitable for the blending of multiple hydrophilic materials and multiple membrane materials. The preparation method is simple, easy to operate, mild in conditions, economic, high-efficiency, environmentally-friendly, easy for industrialization and suitable for the preparation of multi-functional hydrophilic micro-filtration membranes, ultra-filtration membranes, nano-filtration membranes, reverse-osmosis membranes, positive-osmosis membranes, pressure-delay osmosis membranes, pervaporation membranes and the like which are used for liquid and gas separation and membrane reactors.
