A highly flexible inorganic framework with amphiphilic amine assemblies as templates.

A zinc phosphite-phosphate framework, (HA)2[Zn3(HPO3)4-x(HPO4)x] (1; A = cha, coa, iba, pa, and ha; x = 0.3-1) with nanometer-scale channels was prepared. The framework exhibited an extraordinarily high flexibility, 13% expansion at ambient pressure and 27% contraction under a high pressure of over 2.3 GPa without undergoing any phase transformation. The volume changes in the compression-decompression process are reversible. Such unusual adaptability is rare in pure inorganic networks. The molecular volumes of templates range from 165 Å3 to 228 Å3, which allows to vary channel aperture increasingly from 13.02 to 15.34 Å. Remarkably, three types of organic amine template assemblies, captured in inorganic frameworks, were identified in this study. Presented herein is the first example that demonstrates a successfully controlled template assembly that helps to obtain a flexible inorganic framework with nanosized pores in a systematic manner.

Crystalline inorganic frameworks with 56-ring, 64-ring, and 72-ring channels.

The development of zeolite-like structures with extra-large pores (>12-membered rings, 12R) has been sporadic and is currently at 30R. In general, templating via molecules leads to crystalline frameworks, whereas the use of organized assemblies that permit much larger pores produces noncrystalline frameworks. Synthetic methods that generate crystallinity from both discrete templates and organized assemblies represent a viable design strategy for developing crystalline porous inorganic frameworks spanning the micro and meso regimes. We show that by integrating templating mechanisms for both zeolites and mesoporous silica in a single system, the channel size for gallium zincophosphites can be systematically tuned from 24R and 28R to 40R, 48R, 56R, 64R, and 72R. Although the materials have low thermal stability and retain their templating agents, single-activator doping of Mn(2+) can create white-light photoluminescence.
