Inclusion Compounds of Diol Hosts Featuring Two 9-Hydroxy-9-fluorenyl or Analogous Groups Attached to Linear Spacer Units

Abstract

A series of new clathrate host molecules 1−15, each containing two 9-hydroxy-9-fluorenyl or analogous terminal groups attached to linear central units of different lengths and structural compositions, has been synthesized. Their crystalline inclusion compounds with a variety of organic guests − including amines, alcohols, ketones, and other di-

Crystalline Inclusion Compounds of a Palladacyclic Tetraol Host Featuring o‐Carborane Units

“…The possibility of solving the X‐ray diffraction crystal structures of the different inclusion compounds of 2 (Figure ) allowed us to further analyze the nature of the host–guest interactions (Table and Figures S2,S3). The solid‐state structures for the eight inclusion compounds presented in this work constitute examples of lattice‐inclusion compounds with small molecular guests . One remarkable point is the host/guest stoichiometric ratios of 1:6 to 1:8, which are exceptionally high, with respect to the guest component.…”

Supramolecular behaviour of bulky arylboranes in the crystalline state

“…In case of diborane 3 and particularly in 4, this gives rise to a molecular structure being suggestive of the so-called wheel-and-axle (26,27) or dumb-bellshaped compounds (28,29). The latter compounds are typical of their distinct behaviour to be effective clathrate hosts (15,30).…”

Inclusion Compounds of Bulky Binaphthyl-type Bis-fluorenol Hosts

“…The inclusion compounds were obtained by recrystallization of the host compound from the respective guest solvent. The drying conditions specified in the Experimental section (1 h, 15 Torr, room temperature) refer to what we consider a 'stable clathrate' [14].…”

“…Characteristic building blocks in the construction of these frameworks are central biaryl units with 9-hydroxy-9-fluorenyl moieties attached to them [12]. Such a combination of construction elements has proved to be highly efficient in many cases, including cocrystalline and adsorptive compound separation [13,14]. A sample compound of a respective host is specified by formula 1, which is a parent of the substituted analogs 2 -4 (Scheme 1).…”
