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

Novel trans-stereoregular silylene-carbazolylene-vinylene derivatives (13-15) were synthesized via silylative coupling reaction of 3,6-bis(dimethylvinylsilyl)-N-alkylcarbazole (7-9) catalyzed by ruthenium-hydride complex RuHCl(CO)(PCy3)2 (1). All products were isolated, fully characterized by spectroscopic methods and GPC analyses and their absorption and fluorescence properties were determined.

(Figure Presented) A novel π-conjugated polymer (PCPyrene) containing N-benzylcarbazole and pyrene units has been synthesized and characterized. The polymer possesses high thermal stability with the decomposition temperature of 440°C. It shows higher fluorescence quantum yields of in solution and solid state, respectively. PCPyrene can emit bright blue-lights both in different organic solutions (440-460 nm) and in the solid state (492 nm). Compared the emission spectra of PCPyrene in solutions with in solid state, the solid state emission of PCPyrene is significantly red-shifted. Additionally, it is not obvious changes of the solid emission spectra even after being annealed at 150°C under nitrogen for 24 h. The electrochemical properties and energy levels of PCPyrene were also investigated by cyclic voltammetry. Furthermore, in order to provide a basis forecasting the structure-physical property relationships, the photophysical properties of PCPyrene have been carefully investigated by fluorescence emission and UV-vis absorption spectra.

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.

Environment-sensitive luminophoric molecules have played an important role in the fields of smart materials, sensing, and bioimaging. In this study, it was demonstrated that depending on the substituents, 9-aryl-3-aminocarbazoles can display aggregation-induced emission and solvatofluorochromism, and the operating mechanism was clarified. The application of these compounds to lipid droplet imaging and fluorescent probes for cysteamine was demonstrated.

A series of carbazole based ligands with different lengths were assembled with nickel ions to construct metal-organic macrocycles. High-resolution mass spectrometry and ion mobility-mass spectrometry have been used to analyse the resulting MnLn assembly coexisting in solution. Combining with the structural analysis of their solid confirmation, it was revealed that the diversity of the metal-organic macrocycles was increased with the flexibility of the ligands.
