Shirai, Satoshi,Kido, Junji
, p. 386 - 387 (2002)
Fluorescent vinyl polymers containing 9-phenylanthracene pendants were synthesized and examined as an emitter layer in organic electroluminescent devices. The single layer polymer EL device using the homopolymer emitted green light originating from the ex

The potential expansion of the variety of catalytic methods for carbon–carbon bond formation is explored in many research centers all over the world. In this work, we describe very precise and controlled catalytic transformations as useful tools for the synthesis of new trans-π-conjugated molecular organic compounds. The combination of Suzuki–Miyaura coupling and cross-metathesis reactions is established as a simple and efficient method for the design of new (E)-stilbenes in the presence of well-defined transition-metal catalysts at 0.0001–1 % loadings. All of the desired products are isolated in good-to-excellent yields (up to 96 % isolated yield) with high purity.

Double-decker silsesquioxanes have gained a high reputation in many branches of chemistry and process development. In particular, catalytic processes that convert double-decker silsesquioxanes into important functional classes of fine chemicals are a central topic of contemporary organosilicon chemistry. Although the 9,19-di(hydro)octaphenyl double-decker silsesquioxane (DDSQ-2SiH) is known, we report its cis and trans structure and X-ray structure for the first time. The combination of DDSQ-2SiH in a known hydrosilylation reaction protocol with precise reaction time control (FT-IR in situ apparatus) allowed us to selectively assemble a series of previously unreported molecular double-decker silsesquioxanes with ethyl bridged π-conjugated arenes. These compounds were used as a molecular model to obtain their respective macromolecular hybrid analogues. The obtained compounds were characterized spectroscopically and their thermal parameters were also verified.
Synthesis of new styrylarenes via Suzuki-Miyaura coupling catalysed by highly active, well-defined palladium catalysts

An efficient synthetic route for well-defined palladium(0) complexes [Pd(η2-dba)(PPh3)2] (2), [Pd(η2-dba)(PCy3)2] (3) and their crystallographic structures is reported. This is the first crystallographic characterization of palladium complexes coordinated with one dibenzylideneacetone and two phosphines. A highly effective, fully controlled method for selective synthesis of mono- (5-9) and distyrylarenes (10-15) via Suzuki-Miyaura coupling is described. ? The Royal Society of Chemistry 2013.
Rhodium-catalysed anomalous dimerization of styrenes involving the cleavage of the ortho C-H bond
Tobisu, Mamoru,Hyodo, Isao,Onoe, Masahiro,Chatani, Naoto
supporting information; experimental part, p. 6013 - 6015 (2009/05/06)
The dimerization of styrene derivatives in the presence of a rhodium catalyst proceeds to give stilbene derivatives, in which the ortho C-H bond of styrenes is cleaved and functionalized. The Royal Society of Chemistry.
