Inclusion compounds with mixed guests: controlled stoichiometries and kinetics of enclathration

Kinetic Gate‐Opening Process in a Flexible Porous Coordination Polymer

“…As the temperature increased, the value of k go decreased, which is consistent with the temperature dependency of P go (see the http://www.wiley-vch.de/contents/jc_2002/2008/z705822_s.pdf). Such anti‐Arrhenius behavior was observed in clathration reactions of an organic host 13. Anti‐Arrhenius behavior is usually indicative of a multistep mechanism (see the http://www.wiley-vch.de/contents/jc_2002/2008/z705822_s.pdf).…”

“…12 In spite of their importance, few attempts have been made to determine the kinetics of the gate effect 11. 13 Herein, we present the synthesis, crystal structure, and gas sorption properties of a flexible PCP, {[Cd(bpndc)(bpy)]} n ( 1 ; bpndc=benzophenone‐4,4′‐dicarboxylate, bpy=4,4′‐bipyridyl), which shows a large difference in P go between O 2 , Ar, and N 2 (Figure 1). To understand the mechanism behind the differences between similar gases, we treat this phenomenon with the aid of a new diffusion model in which adsorption proceeds through the formation of an intermediate.…”

Guest Exchange in a Robust Hydrogen-Bonded Organic Framework: Single-Crystal to Single-Crystal Exchange and Kinetic Studies

“…We have also investigated the kinetics of guest exchange in 1·THF . Various host complexes have been widely studied for their abilities to encapsulate or release various molecules. ,,− The kinetics of guest uptake or encapsulation into an empty framework or a host structure has been studied, − and the inclusion and desolvation kinetics of host–guest compounds has also been investigated. − There have been some studies on guest exchange in host–guest systems, − but there are very few examples of investigation into the kinetics of guest exchange in framework systems, particularly hydrogen-bonded organic frameworks . If the mechanisms involved during guest exchange in such systems are better understood, we take a step toward being able to regulate these processes.…”
