, p. 4510 - 4518 (2007/10/03)
A series of star-shaped molecules with a silyl group and an aromatic core surrounded by extended π conjugative arms has been synthesized by the use of Sonogashira coupling methods. They show excellent fluorescence intensity with high quantum yield. These
Nickel hemiporphyrazines as bisdienes and bisdienophiles: synthesis and characterization
Rack, Michael,Hauschel, Bernd,Hanack, Michael
, p. 237 - 242 (2007/10/02)
The bisdienophilic (hemiporphyrazinatojnickel complexes 1a-d bearing various alkoxy groups were synthesized from diiminoisoindoles 9a-d, diaminopyridines 10a, d, and nickel acetate. Reaction of 1a-d with an excess of pentaene 3 delivered the macrocyclic bisdienes 2a-d. The hemiporphyrazines were characterized by 1H- and 13C-NMR spectroscopy. The NMR spectra of the 1,6,16,21-tetrabutoxy-substituted compounds 1b and 2b are discussed with respect to the presence of syn/anti isomers. VCH Verlagsgesellschaf; mbH, , 1996.
