Specifically disclosed is a polycarbonate containing a group having a siloxane structure at an end and an arylgroup at a specific ratio.
本发明是在末端以特定的比例含有具有硅氧烷结构的基团和芳基的聚碳酸酯。
2
Self assembly of arylgroup containing flexible bidentate ligands with metal ions gives rise to many types of novel structures because of their variable coordination modes.
芳基柔性二齿配体的配位构型多变，使得其金属配合物的结构丰富多彩。
3
Various aryl triflates, bearing ketone or aldehyde groups, were evaluated for palladium-mediated introduction of an amino group at the triflate position in the presence of various phosphine ligands.
