A new sidechain-based statistical anthracene-containing poly(arylene-ethynylene)- alt -poly(p-phenylene-vinylene) (P2 ) bearing 2-ethylhexyloxy and decyloxy side chains was synthesized to study the effect of elongating sidechain length from octyloxy (as in P1 P2 on photovoltaic performance. The polymer prepared using Horner-Wadsworth-Emmons olefination reaction two dialdehydes with bisphosphona...

After an extensive search for the type specimens of Caecum floridanum Stimpson, 1851, we believe that these specimens may have been either lost or destroyed in the Chicago fire (1871). This paper presents a redescription of the species and a neotype is designated based on material from the type locality (Florida).

The synthesis of (3R )-3-[Boc-Lys(biotinyl)-O ]-11-cis-retinol bromoacetate and 3-[Boc-Lys(biotinyl)-O ]-all trans-retinol chloroacetate is described. These biotinylated retinoids are instrumental in labeling the retinol binding proteins (RBPs) via a nucleophilic displacement of the haloacetate by a residue in the binding site of the protein. The covalently linked biotin will allow for a facile...
