Fluorescent silicone polymers have attracted much attention owing to their strong fluorescence and high stabilities. However, most of these silicone polymers have suffered from fluorescence quenching caused by aggregation in high concentrations. In this w

A Superior Synthesis of Longitudinally Twisted Acenes

Seven longitudinally twisted acenes (an anthracene, two tetracenes, three pentacenes, and a hexacene) have been synthesized by the addition of aryllithium reagents to the appropriate quinone precursors, followed by SnCl2-mediated reduction of their diol intermediates, and several of these acenes have been crystallographically characterized. The new syntheses of the three previously reported twisted acenes, decaphenylanthracene (1), 9,10,11,20,21,22-hexaphenyltetrabenzo[a,c,l,n]pentacene (2), and 9,10,11,12,13,14,15,16-octaphenyldibenzo[a,c]tetracene (14), resulted in a reduction of the number of synthetic steps. As a consequence their overall yields were increased by factors of 50-, 24-, and 66-fold, respectively. All of the twisted acene syntheses reported here are suitable for the synthesis of at least gram quantities of these remarkable hydrocarbon materials.

CARBON MONOXIDE-RELEASING MOLECULES AND THERAPEUTIC APPLICATIONS THEREOF

Carbon monoxide-releasing organic molecules are described herein. The molecules can be synthesized prior to administration (e.g., ex vivo) or formed in vivo. In those embodiments where the molecules are formed in vivo, reactants are administered under physiological conditions and undergo a cycloaddition reaction to form a product which releases carbon monoxide. In applying such reactions for therapeutic applications in vivo, the cycloaddition and CO release typically occur only under near-physiological or physiological conditions. For example, in some embodiments, the cycloaddition reaction and/or release of carbon monoxide occur at a temperature of about 37° C and pH of about 7.4. Pharmaceutical compositions and methods for release carbon monoxide are also described.
