Preparation and magnetic properties of Mn-doped porous carbon nitride sheets

We report a simple method to fabricate Mn-doped poly(triazine imide) (PTI) by using melamine and cyanuric chloride as the building blocks, and Mn as the coupling agent. This material forms a two-dimensional imide-bridged triazine (C6N9H3) network, with an ordered arrangement of 24-atom voids. The synthesized PTI exhibits a large magnetization due to the localized d-electrons of Mn2+ ions, which suggests that PTI contains a large number of Mn2+...
