Reticular Synthesis of Microporous and Mesoporous 2D Covalent Organic Frameworks

Figure: Co-condensation of boronic acid building blocks (BTBA, BTPA, BPDA) with HHTP to give 2D COFs (COFs-6, -8, and -10) having systematically designed porous structures. COF illustrations are to scale. Coloring scheme: C, gray; H, white; B, orange; O, red.

Reticular chemistry is concerned with linking molecular building blocks into predetermined periodic structures using strong bonds.1 This chemistry has led to the design and synthesis of new porous materials for which the composition, structure, metrics, and functionality can be systematically varied.

"Gassing Up with Hydrogen" Researchers are working on ways for fuel-cell vehicles to hold the hydrogen gas they need for long-distance travel

On a late summer day in Paris in 1783, Jacques Charles did something astonishing. He soared 3,000 feet above the ground in a balloon of rubber-coated silk bags filled with lighter-than-air hydrogen gas. Terrified peasants destroyed the balloon soon after it returned to earth, but Charles had launched a quest that researchers two centuries later are still pursuing: to harness the power of hydrogen, the lightest element in the universe, for transportation.

Zeolite A Imidazolate Frameworks

Faujasite (FAU) and zeoliteA(LTA) are technologically important porous zeolites (aluminosilicates) because of their extensive use in petroleum cracking and water softening. Introducing organic units and transition metals into the backbone of these types of zeolite allows us to expand their pore structures, enhance their functionality and access new applications. The invention of metal-organic frameworks and zeolitic imidazolate frameworks (ZIFs) has provided materials based on simple zeolite structures where only one type of cage is present.
