Complexation with diol host compounds. Part 14. Inclusion compounds of 2,2′-bis(9-hydroxy-9-fluorenyl)biphenyl with acetonitrile, cyclohexanone, di-n-propylamine and dimethylformamide

Crystalline Complexes of 2,2′-Bis(9-hydroxy-9-fluorenyl)biphenyl Host with Oligofunctional and Conjugate Functional Group Guests

“…. O1 2.700(2)-2.869(5)Å ], which is also present in the previous structures involving this host compound [13][14][15][16][17][18][19]. Although the phenyl rings are arranged nearly orthogonal to each other (t 1 ¼ 90.0-93.98), the torsion angles t 2 and t 3 range between 216.58 and 29.58, and 215.38 and 28.18, respectively, indicating conformational freedom of the fluorenyl moieties with regard to their adjacent phenyl rings.…”

2,2′-Bis(9-hydroxy-9-fluorenyl)biphenyl–ethyl acetate (1/1)

“…droxy-9-fluorenyl)biphenyl (I) is a host compound with good clathrate-forming ability and the crystal structures of its inclusion compounds with acetonitrile, cyclohexanone, n-propylamine (Barbour et al, 1993), acetone (three solvates) (Sardone, 1996;Ibragimov et al, 2001) and chloroform (two solvates) (Sumarna et al, 2003) were reported. Here, we report the crystal structure of a host-guest complex of (I) with ethyl acetate which resembles closely that of (I) with acetone (1/1) (Sardone, 1996).…”

Crystal structure of 2,2′′-bis(2,7-dichloro-9-hydroxy-9H-fluoren-9-yl)-1,1′:4′,1′′-terphenyl triethylamine trisolvate

“…Compounds featuring two bulky 9-hydroxy-9-fluorenyl moieties laterally attached to a linear central unit such as a biphenyl group (Weber et al, 1993;Barbour et al, 1993;Ibragimov et al, 2001;Skobridis et al, 2007) or other linear combinations of phenylene and ethylene components (Weber et al, 2002) are well known for their high ability to form crystalline host-guest inclusions (Weber, 1996). Both exchange of the central biphenyl axis for a 1,1 0 :4 0 ,1 00 -terphenyl moiety [cf.…”
