Poly(triazine imide) or PTI is an ordered graphitic carbon nitride hosting S-scale pores attractive for selective mol. transport. AA′-stacked PTI layers are synthesized by ionothermal route during which ions occupy the framework and occlude the pores. Synthesis of ion-free PTI hosting AB-stacked layers has been reported, however, pores in this configuration are blocked by the neighboring layer. The unavailability of open pore limits application of PTI in mol. transport. Herein, we demonstrate acid treatment for ion depletion which maintains AA′ stacking and results in open pore structure. We provide first direct evidence of ion-depleted open pores by imaging with the at. resolution using integrated differential phase-contrast scanning transmission electron microscopy. Depending on the extent of ion-exchange, AA′ stacking with open channels and AB stacking with closed channels are obtained and imaged for the first time. The accessibility of open channels is demonstrated by enhanced proton transport through ion depleted PTI. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8COA of Formula: ClLi).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.COA of Formula: ClLi
