Synthesis and structure of 2-phenyl-4-aryl-3,4,5,6-tetrahydrobenzo[h]quinazolines
摘要:
The reaction of 2-arylidene-1-tetralones 1 with benzamidine gave 2-phenyl-4-aryl-3,4,5,6-tetrahydrobenzo[h]quinazolines 2. Investigations on the tautomeric equilibria of 2 by IR, H-1- and C-13-NMR showed the compounds to exist predominantly in the tautomeric form 2A both in the solid state and in solution. Acetylation and oxidation of the heterocyclic ring of 2 provided further evidence for the structural assignment of the title compounds.

Disclosed are electroluminescent devices that comprise organic layers that contain certain organic compounds containing one or more pyrimidine moieties. The organic compounds containing one or more pyrimidine moieties are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.
