Simple reaction conditions and recyclable reagents are crucial for environmentally friendly industrial applications. An environment-friendly, recyclable and economic strategy was developed to synthesize diaryl chalcogenides by the CuCl2-catalyzed C–S bond-formation reaction via iodobenzenes and benzenethiols/1,2-diphenyldisulfanes using N,N′-dimethylethane-1,2-diamine (DMEDA) as ligand, base, and solvent
The invention relates to a method for manufacturing an inkjet ink including a polyamic acid (A), including a step of at least reacting one or more compounds selected from the group of a monoamine (a3) and a compound having one acid anhydride group (a4) with a compound having two or more acid anhydride groups (a1) and a diamine (a2).
The present invention relates to photoaligning material with lateral substitution, compositions thereof, and its use for optical and electro optical devices, especially liquid crystal devices (LCDs).
