ratio, sugar-decorated 2Dnanosheets are ideal candidates for the capture and agglutination of bacteria. Herein, the design and synthesis of two carbohydrate-based Janus amphiphiles that spontaneously self-assemble into high aspect ratio 2D sheets are reported. The unique structural features of the sheets include the extremely high aspect ratio and dense display of galactose on the surface. These structural
Linear polymers alternating oligophenylenevinylene (OPV) moieties and C60 subunits have been prepared in good yields by polycondensation of a bifunctional fullerene derivative with an OPV monomer bearing two alcohol functions. These polymers have been characterized by NMR, UV/vis and their molecular weights determined by size-exclusion chromatography coupled with light scattering.

We report the first cellular application of a photoclick SPAAC reagent to label azide-functionalized RNA. 350 nm irradiation of a cyclopropenone caged oxo-dibenzocyclooctyne (photo-ODIBO) biotin yields formation of the SPAAC reactive species, which rapidly forms adducts with RNA containing 2'-azidoadenosine (2'N3-A). Photo-ODIBO was found to be highly stable in the presence of thiols, conferring greater

application of nitroxide exchange reactions of surface‐bound alkoxyamines as a tool for reversible chemical modification of self‐assembled monolayers (SAMs). This approach is based on radical chemistry, which allows for introduction of various functional groups and can be used to reversibly introduce functionalities at surfaces. To investigate the scope of this surface chemistry, alkoxyamines with different
