Iptycene-Derived pyridazines and phthalazines

(Chemical Equation Presented) The synthesis of new heterocyclic oligo(phenylene) analogues based on soluble, nonaggregating 1,2-diazines is reported. Improved palladium-catalyzed reductive coupling methods were developed to allow for the preparation of la

Orbital unsymmetrization affects facial selectivities of Diels-Alder dienophiles

We investigated the Diels-Alder reactions of maleic anhydrides embedded in a dibenzobicyclo-[2.2.2]octatriene motif as a nonsterically biased dienophile. Substituents on a benzene ring in these dienophiles are far from the reaction center, providing a sterically equivalent π-face. Instead substituents can unsymmetrize the dienophilic π face through π* (anhydride)-π* (aromatic) orbital interactions. Electron-withdrawing substituents affect the facial bias and relative rates of these cycloadditions. The preference of the cycloadditions is opposite in direction to those observed in nucleophilic additions of 2-substituted-9,10-dihydro-9,10-ethanoanthracen-11-ones (dibenzobicyclo-[2.2.2]octadienones) and in electrophilic additions of 2-substituted 9,10-dihydro-9,10-ethenoanthracenes (dibenzobicyclo[2.2.2]octatrienes), though all of them have related dibenzobicyclic systems.

Ptycene-modified pyridazine iridium complex phosphorescent materials, and its preparation and application

The invention discloses ptycene-modified pyridazine iridium complex phosphorescent materials, and its preparation and application. According to the invention, ptycene-modified tricyclic metal iridium complexes and dicyclic metal iridium complexes with pyridazine cyclometalated ligand can be prepared by changing preparation conditions and have general structural formulas as shown in a formula (I) and a formula (II), respectively. Since rigid unconjugated ptycene structures wrapping iridium nucleuses are introduced into ligand in preparation of the phosphorescent iridium complexes, the luminous efficiency and color purity of the iridium complex phosphorescent materials are maximally improved. The prepared ptycene-modified tricyclic metal iridium complexes and dicyclic metal iridium complexes with the pyridazine cyclometalated ligand have high internal and external quantum yield, brightness and stability. A luminescent layer in an electroluminescent device provided by the invention is prepared by using a spin-coating film preparation method under specific conditions, and the prepared luminescent layer is simple to prepare, has low cost, stable chemical properties and high brightness and efficiency and is beneficial for preparation of a high-efficiency electroluminescent device.
