Isostructurality of quinoxaline crystal phases: The interplay of weak hydrogen bonds and halogen bonding

Tailoring the physical properties of molecular crystals though the construction of solid solutions requires the existence of isostructural crystals. Simple substitutions of a given molecular framework can give a range of different crystal structures. A se

Quinoxaline derivatives and application thereof in organic light-emitting devices

The present invention discloses a novel organic compound having a structure represented by the formula shown in the specification, wherein L1 and L2 are each independently selected from one of a single bond, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C3-C30 heteroarylene group, wherein Ar1 is selected from one of substituted or unsubstituted C3-C30 heteroaryl groups containing at least two heteroatoms, and Ar2 is selected from one of substituted or unsubstituted C6-C30 aryl groups and substituted or unsubstituted C3-C30 heteroaryl groups. When the compound provided by the invention is used as a luminescent material in an OLED device, excellent device performance and stability are shown. The invention also discloses an organic light-emitting device adopting the compound with the general formula.

NHC-initiated cascade, metal-free synthesis of quinoxaline derivatives under solvent-free conditions

2,3-Diaryl quinoxaline derivatives have been efficiently synthesized by cascade, metal-free, and solvent-free reaction of aryl aldehydes with aryl 1,2-diamines initiated by N-heterocyclic carbene. Compared with reported methods, this procedure has the advantages of easy work-up, reduced energy consumption, and elimination of solvent waste, hazards, and toxicity. A group of potentially bioactive compounds has been prepared for biomedical screening.

One-pot synthesis of quinoxalines starting from aldehydes under metal-free conditions

An efficient and convenient synthesis of quinoxalines from easily available aldehydes was performed as a one-pot procedure in good to excellent yields under metal-free conditions, via sequential benzoin condensation, aerobic formation of benzils and condensation of the latter with 1,2-diaminobenzenes.

The synthesis of quinoxalines by condensation reaction of acyleins with o-phenylenediamine without solvent under microwave irradiation

A convenient synthetic method for 2,3-disubstituted quinoxalines is described. Heating the aryl or alkyl acyloins and o-phenylenediamine in a microwave oven for 3-6 minutes affords 2,3-disubstituted quinoxalines in 20-94% yields.
