Abstract Pure-organic red exciplex emitters are far from satisfactory in terms of quantity and efficiency. The narrow lowest unoccupied molecular orbital (LUMO) energy levels range reported acceptors together with the intrinsic exciton non-radiative decay dominant factors restricting progress exciplexes. Herein, two acceptor molecules operating at unique LUMO -3.51 -3.56 eV, namely 4-(6-([1, 1’...

Occurrence of emerging organic micropollutants in water bodies and their effects are a concern related to quality reused water. Advanced oxidation processes have demonstrated promising results address this challenge. Nonetheless, these may lead the generation more toxic by-products. The aim study was investigate coupling ozonation nanofiltration (NF) applied carbamazepine (CBZ). It consisted mo...

vilsmeier-haack reaction of 2,3,3-trimethyl-3h-benzo[g]indole, then aqueous basic work-up, leads to benzo[g]indol-2-ylidene- malondialdehydes. these react with various arylhydrazines and quinolin-2-ylhydrazine to form 3,3-dimethyl-2-(1-aryl-1h-pyrazol-4-yl)- 3h-benzo[g]indoles in good yields.

quinazolinones are heterocyclic and water insoluble compounds with various pharmacological and biological characteristics (antibacterial, antiswelling, antifungal, parkinson and etc.). they are used for treatment hiv and cancer. this study investigated the effects of 4(3h) quinazlonones-2-ethyl-2-phenyl ethyl (qepe) as a new quinazolinons compounds on the spleen and immunocompetent cells of new...

Land subsidence has to be controlled under global climate change and sea level rising for coastal megacities. caused by lowering groundwater during underground excavation become a dominant influence factor land urbanization city renewal. How manage the induced foundation pit dewatering (FPD) on an urban scale was urgent. Shanghai selected as research background. A drawdown double control (SDDC)...

3-((4-(dimethylamino)benzylidene)amino)-2-methylquinazolin-4(3H)-one (3), 3-((4hydroxybenzylidene)amino)-2-methylquinazolin-4(3H)-one (4), 2-methyl-3-(pyrrolidin-2-ylideneamino) quinazolin-4(3H)-one (5) and 3,3'-((1,4-phenylenebis(methanylylidene)) bis(azanylylidene))bis(2methylquinazolin-4(3H)-one) (6) derived from 3-amino-2-methylquinazolin-4(3H)-one have been synthesized and characterized by...
