We developed four new ferrocene containing alkylated silane self-assembled monolayers (SAMs), and evaluated their electrical properties in a metal/SAM/metal configuration. The ferrocenyl silanes used in this work can be prepared in one to two simple chemical steps from readily available ferrocene carboxaldehyde. We found that the molecular diodes obtained from these molecules can exhibit current rectification ratios as high as 150. The ease of processing coupled with the excellent rectification behavior makes these compounds very attractive for molecular electronics applications. (C) 2017 Published by Elsevier B.V.

Owing to hydrophobic interactions, silyl linkers containing long alkylene chains allowed the synthesis of self-organised hybrids. Lamellar organo-silicas with phenylene or a hydrogen-bonded adenine⋯thymine complex as the bridging units are reported.
To provide a technique by which an —OH group can be effectively formed on a material surface for the purpose of making the material suitable for bonding (for example, for molecular bonding) that utilizes a chemical reaction (chemical binding). [Solution] A bonding method for bonding a substrate A and a substrate B, which comprises: a step for applying an agent that contains the compound (α) described below on the surface of the substrate A; a step for arranging the substrate B so as to face the compound (α) that is present on the surface of the substrate A; and a step for integrally bonding the substrate A and the substrate B by applying a force onto the substrate A and/or the substrate B. The compound (α) is a compound that has an OH group or an OH-forming group, an azide group and a triazine ring in each molecule, and the substrate A is configured using a polymer.

The influence of the intrinsic self-assembling properties of rigid or semirigid aromatic units as the main substructures combined with the effect of the alkylene side chains as linkers on the nanostructure of bridgedsilsesquioxanes was studied. The symmetry of the organic units was found to control the dimensionality of the hybrid nanostructure. Bis(silylated) aromatic units lead to lamellar hybrids

A simple route to omega-aminoalkyltriethoxysilanes with variable alkylene chain lengths, (EtO)(3)Si(CH2)(n)NH2 (n = 5, 11) is described. These silyl linkers have been used to prepare urea-based compounds with H-bonding and hydrophobic interactions which enable the self-assembly of the molecules. These molecular precursors are suitable for the obtention of nano-structured hybrid silicas. (c) 2005 Elsevier B.V. All rights reserved.
