Abstract:In this work, a new covalent triazine framework based on phthalazinone-containing dinitrile building blocks was prepared by the dynamic nitrile-trimerization reaction. The FT-IR spectra of BCTF illustrated the characteristic peaks of the triazine at 1503 cm(-1) and 1360 cm(-1). The nitrogen sorption isotherm (Type-I) showed a rapid uptake at low pressure (0-0.1bar) indicating a permanent microporous nature. Pore size distribution lower than 2nm was calculated using nonlocal density functional theory (NL-DFT). TGA results showed that BCTF polymer with the skeleton decomposition temperature above 500 degrees C had relatively excellent thermal stability.
