A series of A‐B type sterically regular bicyclio[3.3.0] diene‐based polymers were designed and synthesized as immobilized chiraldieneligands for asymmetric catalysis. With polymericdiene 6b, good to excellent enantioselectivities can be achieved in Rh‐catalyzed asymmetric 1,4‐addition of arylboronic acids to α,β‐unsaturated ketones.

Violet-blue emission from novel aromatic bis(diazaborole)s, which were synthesized by the reaction of 2,5-bis(hexyloxy)-1,4-phenylenediboronic acid and 1,2-phenylenediamine derivatives or diaminonaphthalene derivatives, is described. White-blue emission from a 4-methoxy-1,2-phenylenediamine-derived molecule was observed in DMF using 340 nm as the excitation wavelength.

concept of allostericcooperativity used in biology, chemistry and physics states that any change in the intermolecular host–guest interactions operating in multisite receptors can be assigned to intersite interactions. Using lanthanide metals as guests and linear multi‐tridentate linear oligomers of variable lengths and geometries as hosts, this work shows that the quantitative modeling of metal loadings

The design and synthesis of a ferrocenylmethylphosphine-containing polymer and its application as efficient ligands for the room-temperature Pd(0)-catalyzedcross-coupling reaction of aryl chlorides with arylboronic acids, for which corresponding monomeric monophosphines are totally inactive, are described. Our work demonstrated that rather small monophosphine moieties such as RPPh2 can be used as
Soluble poly(p-phenylene) derivatives with fused thiadiazole units as well as their model compounds were synthesized and characterized by electron affinity, X-ray analysis, and n-doped conductivity.
