Selective sorption of oxygen and nitric oxide by an electron-donating flexible porous coordination polymer
Porous coordination polymers can form materials that are both crystalline and flexible, creating regular yet dynamic channels that are promising for guest sorption. Guest selectivity is difficult to achieve, however, and typically relies on size- or shape-recognition. A framework has now been assembled that combines charge-transfer interactions and structural flexibility to only accommodate O2 and NO.

Rapid preparation of flexible porous coordination polymer nanocrystals with accelerated guest adsorption kinetics
Porous coordination polymers — PCPs, also known as metal–organic framework materials — have been widely investigated for their useful properties, but controlling their size and shape in a nanocrystalline form is difficult. Now, a rapid method of preparing porous crystalline nanosized PCPs that uses a microemulsion system under ultrasonic irradiation has been reported.
