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.

Space Invaders
Our research was featured in the Aug. 16, '07 issue of Nature.
Space exploration usually
means leaving Earth's
orbit. But chemists are now
burrowing inside solids to
open new vistas. Katharine
Sanderson reports from the
internal frontier.

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.
