Azobenzenes have a unique ability to undergo reversible isomerization between two geometrical isomer forms (the straight trans and the bent cis) when irradiated with the correct wavelength of UV or visible light. These systems are of interest because of their numerous potential applications as reversible photoswitchable absorbers. The azobenzenes can also be used as terminal groups in nickel di...
Dicationic sandwich complexes containing thiophene, 2-methylthiophene7 2,5-dimethylthiophene, and tetramethylthiophene react with ammonia to give salts of the formula [(ring)Ru(SC4R4NH2)lX where ring = CsMe6 or cymene. The thiophene, 2-methylthiophene, and 2,5-dimethylthiophene complexes undergo C-S cleavage to give iminium-thiolato derivatives. In the case of the 2,5-dimethylthiophene complex,...
Metal-doped boron clusters provide new opportunities to design nanoclusters with interesting structures and bonding. A cobalt-doped boron cluster, CoB18-, has been observed recently to be planar and can be viewed as a motif for metallo-borophenes, whereas the D9d drum isomer as a motif for metallo-boronanotubes is found to be much higher in energy. Hence, whether larger doped boron drums are po...
