Abstract

Host-lattice rearrangements in clathrates as a result of sorptive gas exchange are reported for the first time. Unlike any other clathrates, those produced by the recrystallization of bis(9-hydroxyfluoren-9-yl)thieno-[3,2-b]thiohene from ethanol and n-propanol exhibit guest-responsive channel-type cavities: their structure differs for the guest ethanol and propanol. The structures, lattice rearrangements and guest displacement of the system are discussed.
