Porous Ladder Polymer Networks [PDF]
Chem, 2020 Summary Porous ladder polymer networks (ladder PPNs) represent an emerging class of porous organic materials constituted by crosslinked, fully fused ladder-type backbones. Their unique structural characteristic allows for the integration of the properties of porous organic polymers and ladder polymers in a synergistic manner, affording materials ...
