In this paper, we report on the self-assembly of water-soluble N,N′-di(N,N′-dimethyl-dodecane-1,12-diamide)-perylene-3,4,9,10-tetracarboxylic diimide (PDDoAM) in formic acid and chloride salts for producing varied nano-aggregates with different optical properties. Interestingly, the self-assembly can lead to nanocubic, microsheet and “tower-like” nanostructures respectively, as demonstrated by Scanning Electron Microscopy (SEM) images. The optical properties of molecular aggregates were investigated by means of Confocal Raman Microscopy, indicating the morphologies and fluorescence of these nanomaterials are dependent on acids, acid concentrations and casting methods.

A di-tetrazole ligand was used to occupy the edges of a tetrahedron to generate an edge-directed self-assembled Pd12 water soluble cage which was used as a vessel to encapsulate aromatic nitro-olefins. A face directed Pd12 tetrahedral cage was also constructed occupying the triangular faces of the tetrahedron by a tri-tetrazole ligand.

ABSTRACTIn this paper, we present layer-by-layer stacking method to fabricate self-assembled structures of block copolymers (BCP) toward the out-of-plane direction. Layer-by-layer stacking is realized by transferring a BCP film on one substrate to another. Specifically, a water-soluble polymer film is coated on the former substrate, which is placed and fixed in contact with a target substrate. Consequently, the BCP film is released from the substrate and transferred to the target substrate when immersed in de-ionized water. In our experiment, PS-b-PMMA is used to form and transfer self-assembled structures, and polyvinyl alcohol is used as a water-soluble polymer. We prepared two kinds of target substrates; one has horizontal cylindrical structures by BCP self assembly, and the other has groove structures by EB lithography. In the case of BCP patterned substrate, BCP film with vertical cylindrical structures is transferred onto the line structures of BCP. In the case of EB lithography patterned substrate, BCP film with vertical cylindrical structures is transferred in a doubly suspended condition. Furthermore, vertical and horizontal cylindrical structures are also observed to align along the grooves.

Based on self-assembled combination of graphene with Au nanoparticle-doped copper hexacyanoferrate (CuHCF) multilayers, a electrochemical biosensor for sensitive detection of hydrazine has been reported. Graphene was functionalized by wrapping with poly(diallyldimethylammonium chloride) (PDDA). Such polyelectrolyte modified graphene (PDDA-G) was water-soluble and possessed net positive charge. Based on electrostatic self-assembly, graphene multilayers modified electrode (ITO/G-M) was fabricated. After binding with mercaptopropionic acid stabled Au nanoparticles (MPA-AuNPs), three dimensional graphene-AuNPs electrode was obtained. CuHCF multilayers were then formed on AuNPs center by successive self-assembly and solution epitaxy. Due to the synergistic effect of graphene and AuNPs, the developed biosensor (ITO/G-M/CuHCF-M) exhibited fast and sensitive amperometric response for the determination of hydrazine in near physiological pH. The linear response for the determination of hydrazine ranged from 4.0 × 10-7 to 1.3 × 10-4 M with a detection limit of 7.2 × 10-8 M. The biosensor exhibited high reproducibility and stability resulted from simple and reproducible self-assembly methodology.
