Magnetically Induced Amination of Alcohols Using MNi@Cu (M=Fe, Co) Nanoparticles as Catalysts.

The synthesis of tertiary amines from alcohols (i.e. heptanol, dodecanol, cyclohexanol, benzylalcohol) and secondary amines (MeNH (DMA), PrNH, BuNH) has been achieved in one step using trimetallic nanoparticles (NPs) displaying a magnetic core (CoNi and FeNi) and a Cu shell as both catalysts and heating agent in the presence of an alternating magnetic field.

Solution processed organic light-emitting diodes using a triazatruxene crosslinkable hole transporting material.

A cross-linkable triazatruxene that leads to insoluble films upon thermal annealing at temperatures compatible with flexible substrates is presented. The films were used as the hole transporting and electron blocking layer in partially solution processed phosphorescent organic light-emitting diodes, reaching power conversion efficiencies of 24 lm W, an almost 50% improvement compared to the same OLEDs without the cross-linkable hole transporting layer.

Photochemical studies on bis-sulfide and -sulfone tethered polyenic derivatives.

This study focusses on the [2 + 2]-photocycloaddition of a symmetric polyenic system tethered by an aryl bis-sulfide or sulfone platform. Using direct irradiation or photosensitization, no expected ladderane product was isolated. In most cases, only tricyclic products including a single cyclobutane moiety were formed.
