The sorption isotherms are stepped with moderate hysteresis, temperature controlled and saturation uptake is fixed. Such switching, which has rarely been observed, offers the promise of exceptional working capacity for gas storage.

On comprehensive mechanical analyses of these functionalized triazine network polymers, they mark the introduction of mechanical stiffness among all porous organic network materials; recorded stiffness features analogous to their organic-inorganic hybrid polymer analogues, viz. metal-organic frameworks (MOFs). Further, the study presents a new paradigm for the simultaneous installation of mechanical stiffness and high surface hydrophobicity into polymeric organic networks, which has the utilitarian potential to be translated among all porous solids. Control experiments with non-fluorinated congeners could underline the key role of fluorine, in particular, bis(trifluoromethyl)-functionalization behind realizing the dual features of mechanical stiffness and superhydrophobicity.

Luminescent linker derived photoluminescence emission signature together with the reversibly dynamic host polymer exhibited a unique response toward environmentally toxic aromatics in the solid state, arguably crucial for the designed development of toxin-responsive solid materials.

However, a great challenge remains unmet when it comes to successfully fabricating a PP-MOF film with crystallinity, controllable orientation, adjustable morphology and thickness, all sustained in one. Herein, for the first time, vaporassisted conversion (VAC) was developed as a facile and versatile technique to fabricate functional PP-MOF films on various substrates related to different application requirements. To understand the nucleation and growth mechanism, a number of fabrication methods were leveraged to prepare the PP-MOF films, thanks to an assortment of PP-MOFs varying from two-dimensional (2D) to threedimensional (3D) scaffolds. The studies show that PP-MOF films are likely to display different nucleation and growth processes following different deposition approaches. This study demonstrates the pros and cons of different methods in the fabrication of functional PP-MOF films, potentially offering critical tools and reference points for the preparation of next-generation functional MOF thin films in general.
