Click functionalization of a dibenzocyclooctyne-containing conjugated polyimine

A conjugated poly(phenyl-co-dibenzocyclooctyne) Schiff-base polymer, prepared through polycondensation of dibenzocyclooctyne bisamine (DIBO-(NH2)2) with bis(hexadecyloxy)phenyldialdehyde, is reported. The resulting polymer, which has

Two-dimensional oligo(phenylene-ethynylene-butadiynylene)s: All-covalent nanoscale spoked wheels

The synthesis and characterization of a shape-persistent two-dimensional (2D) organic compound is described in detail. In a rational modular synthesis of a dodecaacetylene precursor and its subsequent template-aided cyclization, we obtained a molecularly defined, stable, C6-symmetric, rigid, spoked wheel. Peripheral tert-butyl groups and alkyl chains attached to the plane of the molecule provide sufficient solubility, so that the 2D oligomer can be fully characterized by MALDINIS, GPC, and 1HNMR, UV/Vis absorption, and fluorescence spectroscopy. Molecular mechanics and dynamics simulations indicate that the most stable conformer of the molecule in vacuum is a shallow boat conformation with a small dihedral angle. Comparisons with the precursor as well as a ring-only structure clearly reveal the high rigidity of the title compound. Small-angle neutron scattering (SANS) experiments in [D 8]THF and CDCl3 affirm the rigid backbone structure in solution, that is, a radius of about 2.7 nm and a thickness of about 0.22 nm. STM investigations illustrate that the wheel molecules adsorb with their molecular plane parallel to the surface and can form hexagonal crystalline domains (unit cell parameters are a = b = 6.0±0.2 nm and θ=60±2°), with the iert-butyl groups on the apexes staggered. Such staggering induces chirality in the organized domains. AFM investigations demonstrate that the wheel molecules inside overlayers organize in the same way as in the layer directly in contact with the surface. This indicates an epitaxial growth characteristic of the film.

Efficient synthesis of 1,4-dialkoxy and 1,4-dialkyl substituted 2,5-divinylbenzenes via the Stille reaction

An efficient palladium catalyzed cross coupling of tributyl(vinyl)stannane with dialkoxy and dialkyl substituted 1,4-dihalobenzenes is described. This single-step coupling provides an efficient synthesis of functionalized 2,5-divinylbenzenes, which are us
