α- and β-Bis(1,1,1-trifluoro-5,5-dimethyl-5-methoxyacetylacetonato)copper(II): Transforming the Dense Polymorph into a Versatile New Microporous Framework

“…There is however a difference between nonstoichiometric inclusions of urea and β-[CuL 2 ]. In urea inclusions guest species are tightly packed, resulting in the appearance of an independent crystallographic period for the guest subsystem which does not coincide with the respective unit cell period of the urea host framework 27a. This was attributed to the thermodynamic and kinetic instability of the empty urea framework .…”

Design of a Solid Inclusion Compound with Optimal Properties as a Linear Dichroic Filter for X‐ray Polarization Analysis

“…Our design of the 1-bromoadamantane/thiourea inclusion compound was based on the rationale that the adamantane moiety would essentially fill the cage, with the CÀBr bond constrained to project into the narrower window region between adjacent cages and thus oriented essentially parallel to the tunnel axis. It is already known [13] that adamantane forms an inclusion compound with thiourea in which the adamantane guest molecules efficiently fill the cages in the conventional thiourea tunnel structure. Furthermore, thiourea inclusion compounds usually have a needle morphology, with the host tunnel parallel to the needle axis, which would allow straightforward alignment of the crystal in polarization analysis.…”
