PTI is composed of ordered atom-thick g-C 3N 4 layers, and is obtained by the ionothermal synthesis in a eutectic salt melt where the role of salt has been described as the solvent 4b, 13 as well as the structure directing agent. 10 Among the g-C 3N 4 family, PTI has been investigated as a highly attractive material for photocatalysis 6c, 11 and molecular separation. 9 The presence of nanoscale porosity in g-C 3N 4 has also led to exploration for enhanced water and ion transport. 2 Since then, several g-C 3N 4 derivatives, including melon, 3 triazine-based g-C 3N 4 including poly(triazine imide) or PTI, 4 and poly(heptazine imide) 5 have been reported with applications in metal-free photocatalysis, 6 dark photocatalysis, 7 semiconductors, 4a, 8 and batteries. The materials chemistry research for graphitic carbon nitrides ( g-C 3N 4) was initially motivated by the synthesis of β-C 3N 4 framework 1 which could be a material that is “harder than diamond”. The accessibility of open channels is demonstrated by enhanced proton transport through ion depleted PTI. 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. We provide first direct evidence of ion-depleted open pores by imaging with the atomic resolution using integrated differential phase-contrast scanning transmission electron microscopy. Herein, we demonstrate acid treatment for ion depletion which maintains AA’ stacking and results in open pore structure. The unavailability of open pore limits application of PTI in molecular transport. Synthesis of ion-free PTI hosting AB-stacked layers has been reported, however, pores in this configuration are blocked by the neighboring layer. AA’-stacked PTI layers are synthesized by ionothermal route during which ions occupy the framework and occlude the pores. ![]() Mind their properties when you create one and make sure that they won’t fall down at a critical moment!
