Redox-modulated near-infrared electrochromism, electroluminochromism, and aggregation-induced fluorescence change in an indolo[3,2-b]carbazole-bridged diamine system

A new indolo[3,2-b]carbazole-based compound (1) has been developed by linking two redox-active diphenylamine moieties to the rigid pi-conjugated indolo[3,2-b]carbazole core. Its first two completely reversible oxidation steps are mainly related to the two terminal amine centers, and a moderate electron coupling between these amine centers has been determined. The associated oxidized species 1+and 12+both exhibited strong NIR absorptions, and a completely reversible conversion among three different colors (light-yellow, red, and blue, corresponding to neutral, monocationic and dicationic states, respectively) could be realized. In addition, reversible switching between turn-off and turn-on of its fluorescence could be accomplished by electrochemical oxidation and reduction, respectively. Compound 1 also exhibited obvious fluorescence color changes during its aggregate-forming process, and its solid showed bright-yellow fluorescence with a high emission quantum yield of 30%.

Dehydrogenation of compounds with weakened C-H bonds in the presence of platinum and palladium fullerides

Coordinated fullerene acts as a hydrogen acceptor in reactions with compounds having weakened C-H bonds (1,4-dihydropyridine and 9,10-dihydroanthracene). Metal fullerides are the dehydrogenation catalysts. They activate the C-H bonds of dihydroanthracene and diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate in positions 9,10 and 1,4, respectively. No activation of norbornane carbon-hydrogen bonds with metal fullerides was observed under mild conditions. Nauka/Interperiodica 2007.

In this report, a palladium-catalyzed redox-relay Heck process to access optically active alkenylated alpha,beta-unsaturated lactams is described. Under mild reaction conditions, electron-deficient alkenyl triflates and electron-rich alkenyl iodonium salts undergo enantioselective and site-selective coupling with enelactams to deliver the products in high yields and excellent enantioselectivities. Furthermore, the products allow facile access to natural products such as (+)-calvine and (+)-2-epicalvine in addition to the bioactive molecule aza-goniothalamin.

Synthesis of poly(imino imino ketone) (PIIK) and preparation of heat resistant PIIK foam

Poly(imino imino ketone) (PIIK) was synthesized via palladium-catalyzed C-N cross coupling reaction of 1,4-bis-(4?-bromobenzoyl) benzene and p-phenylenediamine. In view of its good thermal stability and solubility, PIIK foams with low density between 80 mg/cm3-350 mg/cm3 have been prepared via thermal induced phase separation and freeze-drying technology. The PIIK foam possessed high glass transition temperature (Tg = 193 C) and good thermal stability with high decomposition temperature (Td = 350 C). Furthermore, these achieved foams also exhibited excellent mechanical properties, such as high modulus and compressive strength, as well as great elongation at break (ca. 20%).
