Abstract

A net gain: A kinetically assembled, but thermally stable network is obtained using the labile metal species [Cu4 I4 (PPh3 )4 ]. The network uniquely adsorbs I2 by chemisorption through I3 (-) formation. The chemisorbed I2 readily desorbs above 380 K owing to the dynamic motion of the framework. A thermodynamically assembled network physisorbs I2 , which is an exact fit for the channel.

Keywords: chemisorption; copper; iodine; metal-organic frameworks; physisorption.
