Layered two-dimensional polymer frameworks were formed on the basis of the thermally-induced auto-condensation mechanism of heptazine (C6N7) in a salt melt of lithium bromide and potassium bromide from three different molecular building blocks. The backbone of the materials is based on strong covalent bonds (C-C, C-N) resulting in high thermal stabilities (< 600 °C) and low bulk density, but no accessible pores.
