چکیده
The search of new organic emitters is receiving a strong motivation by the development ORTP materials. In present study we report on preparation, optical and photophysical characterization, both steady state time resolved techniques, two pyrene-functionalized cyclic triimidazole derivatives. Together with already reported mono-substituted derivative, di- tri-substituted members family have revealed as intriguing characterized impressive quantum yields in solution RTP properties solid state. particular, phosphorescence lifetimes increase from 5.19 to 20.54 40.62 ms for mono-, trisubstituted compounds, respectively. Based spectroscopical results theoretical DFT/TDDFT calculations di-pyrene molecule, differences performances three compounds been assigned intermolecular interactions increasing number pyrene moieties appended scaffold.

متن کاملHighly regio- and stereoselective nitro-oxoamination of mono-substituted allenes.
A highly regio- and stereoselective (up to 99/1) nitro-oxoamination reaction of mono-substituted allene occurs under mild conditions with readily available AgNO2 and a free radical trap TEMPO to form one C-N bond and one C-O bond in one step. Various functional groups and heterocycles could be tolerated in this conversion.

2,4,6-Triisopropylstryrene was synthesized in a single step via the Witting Reaction from the corresponding aldehyde. The reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(M eTD) was investigated. These reactions are instantaneous at room temperature and lead to the formation of 2: 1 ...

The degree of aromaticity of mono-substituted derivatives of benzene has beeninvestigated using a new index based on electric field gradient index, by using two mechanicalquantum methods with Gaussian 03. Two different basis sets have applied to study and theresults compared. This strategy has demonstrated that, due to violation of symmetry in have pisystems,how the degree of aromaticity can ha...
