Janus cylinders are one-dimensional colloids that have two faces with different compositions and functionalities and are useful as building blocks for advanced functional materials. Such anisotropic objects are difficult to prepare with nanometric dimensions. Here we describe a robust and versatile strategy to form micrometer long Janus nanorods with diameters in the 10-nanometer range, by self-assembly in water of end-functionalized polymers. For the first time, the Janus topology is not a result of the phase segregation of incompatible polymer arms, but is driven by the interactions between unsymmetrical and complementary hydrogen bonded stickers. It is therefore independent of the actual polymers used and works even for compatible polymers. To illustrate their applicative potential, we show that these Janus nanorods can efficiently stabilize oil-in-water emulsions.

Self-complementary hydrogen-bonding domains were incorporated as the electron deficient unit in “push–pull”, p-type small molecules for organic photovoltaic active layers. Such compounds were found to enhance the fill factor, compared with similar non-self-organized compounds reported in the literature, leading to higher device efficiencies. Evidence is presented that the ability of these molecules to form one-dimensional hydrogen-bonded chains and subsequently exhibit hierarchical self-assembly into nanostructured domains can be correlated with improved device efficiency.

Abstract Janus cylinders are one-dimensional colloids that have two faces with different compositions and functionalities, and are useful as building blocks for advanced functional materials. Such anisotropic objects are difficult to prepare with nanometric dimensions. Here we describe a robust and versatile strategy to form micrometer long Janus nanorods with diameters in the 10-nanometer range, by self-assembly in water of end-functionalized polymers. The Janus topology is not a result of the phase segregation of incompatible polymer arms, but is driven by the interactions between unsymmetrical and complementary hydrogen bonded stickers. Therefore, even compatible polymers can be used to form these Janus objects. In fact, any polymers should qualify, as long as they do not prevent co-assembly of the stickers. To illustrate their applicative potential, we show that these Janus nanorods can efficiently stabilize oil-in-water emulsions.

Self-assembly of polyazamacricyclic complexes of copper(II), [Cu(H2L1]4+, where L1 = 1,8-bis(2-aminoethyl)-1,3,6,8,13-hexaazacyclotetradecane, and [Cu(H2L2)]2+, where L2 = 1,8-bis(4-butylic acid)-1,3,6,8,13-hexaazacyclotetradecane, [Ni(CN)4]2- produces two-dimensional permanent ring structure (1) and three-dimensional network structure (2), respectively, in crystalline solid. The geometry around copper(II) ion is an z-elongated octahedron (1) and square pyramid (2). Inter molecular hydrogen bonding of 1 produces one-dimensional ring chain and 2 produces one-dimensional zig-zag shape coordination polymer. Hydrogen bonding of neighboring chains of 1 produces two-dimensional permanent ring structure with a nanoscale area and that of 2 produces three-dimensional network structure having one-dimensional channels with nanoscale cross-section in crystalline solid.

A supramolecular compound,catena-poly{[Cu2(1,3-μ2-(1a))2(μ2-ter)2(H2O)2]n·(6H2O)n} (1) has been synthesized using (1a) [(1a=N1,N3,N5-trimethyl-N1,N3,N5-tris((pyridin-4-yl)methyl)-1,3,5-benzene tricarboxamide] and terephthalate (ter) as the pillaring unit by self-assembly. The terephthalate units are connected by copper(II) ions forming a single strand, while a pair of such strands are then linked by (1a)viatwo pyridyl terminal arms bound to copper(II) nodes on either side forming a one-dimensional double stranded assembly propagating along thecaxis. The compound crystallizes in theFdd2 space group. The cavity created in the interior of this double strand assembly trap six water molecules and are stabilized by hydrogen bonding with the host. The arrangement of the pair of acyclic water trimers in isolated cavities of (1) is such that it resembles a closed-bracket-like formation. The Hirshfeld surface analysis of (1) reveals the presence of strong intermolecular hydrogen-bonding interactions between one-dimensional ladder-like units and with the water trimer in the host cavity. The copper(II)-containing coordination polymer also acts as an efficient catalyst for the Glaser–Hay homo-coupling reaction.
