Development of Photosensitive Self-Assembled Monolayer Using Silane Coupling Agents Containing 2-Nitrobenzyl Esters Implied for Application to Cell Array

Smooth, aggregate-free self-assembled monolayer deposition of silane coupling agents on silicon dioxide.

Silane coupling agents (SCAs) are notorious for aggregating during deposition on oxide substrates, leading to nonuniform surface morphologies. To ameliorate this problem, we describe a vapor-phase deposition technique for silane coupling agents employing a spin-coated perfluoropolyether (PFPE) diffusion barrier that facilitates the formation of smooth, aggregate-free self-assembled monolayers (...

Mesophase in a thiolate-containing diacyl phospholipid self-assembled monolayer.

Maintaining the intrinsic features of mesophases is critically important when employing phospholipid self-assemblies to mimic biomembranes. Inorganic solid surfaces provide platforms to support, guide, and analyze organic self-assemblies but impose upon them a tendency to form well-ordered phases not often found in biomembranes. To address this, we measured mesophase formation in a thiolate sel...

Near-field photochemical and radiation-induced chemical fabrication of nanopatterns of a self-assembled silane monolayer

A general concept for parallel near-field photochemical and radiation-induced chemical processes for the fabrication of nanopatterns of a self-assembled monolayer (SAM) of (3-aminopropyl)triethoxysilane (APTES) is explored with three different processes: 1) a near-field photochemical process by photochemical bleaching of a monomolecular layer of dye molecules chemically bound to an APTES SAM, 2...

Fully printable mesoscopic perovskite solar cells with organic silane self-assembled monolayer.

By the introduction of an organic silane self-assembled monolayer, an interface-engineering approach is demonstrated for hole-conductor-free, fully printable mesoscopic perovskite solar cells based on a carbon counter electrode. The self-assembled silane monolayer is incorporated between the TiO2 and CH3NH3PbI3, resulting in optimized interface band alignments and enhanced charge lifetime. The ...
