    摘要: An organic light-emitting device is provided. The organic light-emitting device includes: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, the organic layer including a first compound, a second compound, and a third compound. The first compound, the second compound, and the third compound are each independently an azine-based compound represented by one selected from Formulae 1-1 to 1-5, except for a case where the first compound, the second compound, and the third compound concurrently include an azine-based compound represented by Formula 1-3.

    摘要: Disclosed is a process of cyclically producing hexamethylolmelamine, comprising: adding a mother liquid and high-concentration formaldehyde aqueous solution in a hydroxylation reaction kettle; stirring and heating the solution in the kettle; adding alkali in the reaction kettle, and pre-adjusting a pH value of the solution in the kettle; then adding melamine in the reaction kettle; adding alkali again into the reaction kettle, and adjusting the pH value of the solution in the kettle; raising a temperature of the reaction solution in the kettle for reaction; introducing the solution in the kettle which has already been cooled into a centrifuge for centrifugal separation to obtain hexamethylolmelamine wet material and the mother liquid; delivering the hexamethylolmelamine wet material to a drying system for subsequent drying; returning the mother liquid back to the reaction kettle; and repeating the above steps for cyclic production. By using high-concentration formaldehyde, the present disclosure enables the mother liquid to be cyclically used for a production procedure, thereby substantially reducing the product costs and achieving zero-pollution emission.

    摘要: The present invention relates to novel polyisocyanurate plastics which are obtainable by catalytic trimerization of a polyisocyanate composition A) which contains oligomeric polyisocyanates and is low in monomeric diisocyanates. "Low in monomeric diisocyanates" means that the polyisocyanate composition A) has a content of monomeric diisocyanates of at most 20% by weight. The invention further relates to the use of these polyisocyanurate plastics for production of coatings, films, semi-finished products and mouldings, and to a process for producing polyisocyanurate plastics comprising the following steps: (a) providing a polyisocyanate composition A) which contains oligomeric polyisocyanates and is low in monomeric diisocyanates, "low in monomeric diisocyanates" meaning that the polyisocyanate composition A) has a content of monomeric diisocyanates of at most 20% by weight; (b) catalytically trimerizing the polyisocyanate composition A).

    摘要: Mercapto-containing organosilicon compounds of formula (3) :

    wherein each A independently is a straight or branched C 1 -C 8 alkylene group, each B independently is a straight or branched C 1 -C 8 alkylene group and each E independently is hydrogen or a substituent group of the general formula (4):

    wherein D is straight or branched C 1 -C 8 alkylene group, each R independently is a hydrolysable group, each R' independently is a C 1 -C 4 alkyl group, and m is an integer of 1 to 3, provided that at least one E is a said substituent group of formula (4). They can be used as adhesion improvers for improving the adhesion of a resin to inorganic substrates.
