Abstract
Herein we report the syntheses of two porous hyper-crosslinked polymers (HCPs) via thiol–yne reaction with rigid tetrahedral and pseudo-octahedral core structures. Sorption measurements with nitrogen gas at 77 K revealed BET-surface areas up to 650 m²/g. Those networks also showed a high thermal stability as well as insolubility in common organic solvents.
Highlights
The synthesis of different organic networks has been previously reported
Especially tetraphenylmethane cores are widely employed in the synthesis of covalent organic frameworks (COFs) [1,2], porous aromatic frameworks (PAFs) [3], porous polymer networks (PPNs) [4] and hyper-crosslinked polymers (HCPs) [5]
The second network was synthesized with tetraphenylmethane core 2 and the pseudo-octahedral bistritylbenzene core 4 under the same reaction conditions (Scheme 1)
Summary
The synthesis of different organic networks has been previously reported. Among them, especially tetraphenylmethane cores are widely employed in the synthesis of covalent organic frameworks (COFs) [1,2], porous aromatic frameworks (PAFs) [3], porous polymer networks (PPNs) [4] and hyper-crosslinked polymers (HCPs) [5]. We report the syntheses of two porous hyper-crosslinked polymers (HCPs) via thiol–yne reaction with rigid tetrahedral and pseudo-octahedral core structures. Sorption measurements with nitrogen gas at 77 K revealed BET-surface areas up to 650 m2/g. Those networks showed a high thermal stability as well as insolubility in common organic solvents.
