In this paper we describe a new class of antiaromatic planar cyclooctatetraenes: the diazadioxa[8]circulenes. The synthesis was achieved by means of a new acid-mediated oxidative dimerization of 3,6-dihydroxycarbazoles to yield the diazadioxa[8]circulenes

Reaction of chloromethylated polystyrene (3.90 mequiv/g) beads with triphenylamine and diethylchloroalane resulted in a higly cross-linked polymer.The chloromethylated polystyrene was modified by reaction with 2,6-dibromocarbazole (4) and K2CO3 in DMF at 100 deg C to give an excellent yield of polymer-supported 2,6-dibromocarbazole (5) without concomitant cross-linking.The polymer-bound 2,6-dibromocarbazole was nonreactive toward SbCl5, whereas the homogeneous counterpart 9-N-benzyl-2,6-dibromocarbazole (6) was found to readily generate the aminium cation radical upon reaction with SbCl5.Attachment of phenothiazine to a polystyrene support yielded a reagent that would react very rapidly with SbCl5 in dichloromethane.The polymer-bound phenothiazine cation radical was found to readily oxidize the metal-metal bond in 2 and undergo anion exchange with Bu4NPF6 to afford a more synthetically useful reagent.

A benzhydryl radical based on the stability of the organic light-emitting material at room temperature and using the material preparation of the organic electroluminescent device, which belongs to the field of organic light-emitting technology. The present invention in the preparation of the organic light-emitting material, the center of the common characteristic is the carbon free radical, is composed of two C - C covalent bond and a C - N to form a covalent bond. Stability is the light-emitting free radical material in the application of the key nature, connected to the electronic group conducive to stable free radical, in this invention through the nitrogen-containing heterocyclic carbazole, indole, dimethyl acridine and the like in the electronic group to the nitrogen atom is connected directly to the benzyl group, to obtain a stable benzhydryl radical, its stability and PTM, compared with the TTM is greatly improved, and has a room temperature fluorescent. The preparation of the material of the organic electroluminescent device using double thread condition exciton light-emitting, can avoid the traditional organic electroluminescent device in the use of the triplet state exciton, the maximum external quantum efficiency of the device is 0.66%.
