ABSTRACT
Collectively, this work not only achieves permanent
porosity but also systematically reveals the unique advantages of chalcogen
bonding in electronic structure, structural regeneration, and lattice dynamics.
First, the permanent porosity of Trip3Tez-I (BET surface area of
1,509 m2 g-1) makes it a potential candidate for gas
separation and sensing. Second, the semiconductor-like charge transport
potential, revealed by DFT calculations showing appreciable band dispersion
along the [Te···N]2n ribbons, offers possibilities for applications
in optoelectronics. Third, the material self-heals: sonication in pyridine
after thermal amorphization restores nearly full crystallinity and porosity,
offering potential for healable flexible electronics. These characteristics
make ChOFs a unique and promising class of noncovalent porous frameworks,
warranting further exploration in both fundamental research and potential
applications.
