“…This compound was synthesized from 5-hydroxy-isophthalic acid by a reported procedure in three steps [9,14,33]. Precursor 1 was converted to the bis-chloride 2 by a reaction with methane sulfonyl chloride followed by a simple treatment with suitable reagents (LiPPh 2 , NaSPh, or Me 2 NH) to afford the respective ECE-pincer arene ligand (E = PPh 2 3, SPh 4, NMe 2 5).…”

For the synthesis of (ECE-OH)-pincer Pd-complexes 6 and 7, a direct bis-(ortho)-palladation route was used involving regioselective C-H activation using [Pd(MeCN) 4 ](BF 4 ) 2 as the palladating reagent (Scheme 2) [9].…”

a b s t r a c tVarious para-OH functionalized ECE-pincer metal complexes [MX(ECE-OH)L n ] (ECE-OH = [C 6 H 2 (CH 2 E) 2 -2,6-OH-4] À , E = NMe 2 , PPh 2 and SPh) were synthesized. The X-ray crystal structures of neutral [PdCl(SCS-OH)], [PdCl(NCN-OH)], and cationic [Pd(PCP-OH)(MeCN)](BF 4 ) are reported. The neutral halide complexes exhibit self-assembly to form polymeric chains via H-bonding involving the para-OH group as donors and the halide ligand on the metal as acceptors. Moreover, the halide ligand can be replaced by a monomeric aryloxy-O ligand leading to the formation of a covalently bonded dimer. The crystal structure of such a dimer derived from [PdI(NCN-OH)] is reported. Furthermore, these pincer-metal complexes were tethered through a carbamate linker to a siloxane functionality with the aim to be immobilized on a silica support. The crystal structure of a siloxane-functionalized [PtI(NCN-Z)] complex exemplifies how other H-bonding interactions not involving the metal-halide groupings can lead to polymeric networks as well.

“…The spherical shape of dendrimers is thought to exist in solution, but little is known about their shape in the solid state, although this physical parameter is undoubtedly of great influence on their unique physical properties. In the melt and the solid state, a variety of techniques has suggested that the molecules can adopt either spherical (10)(11)(12) or rod-like (13) shapes. These techniques, however, cannot easily discriminate between discrete molecules and their aggregates.…”

Host molecules with U-shaped receptor cavities have been derivatized at their convex side with two n-hydrocarbon tails (1), two first-generation (2), and two second-generation (3) monodendritic hydrocarbon tails. Although hosts 1 and 2 display plastic-crystalline behavior, evidence suggests that host 3 forms a cubic liquidcrystalline phase. In this phase, molecules of 3 are arranged in spherical supramacromolecular assemblies, in which the receptor cavities are situated in the core and the hydrocarbon tails at the periphery. The 1:1 host-guest complex of 3 with methyl 3,5-dihydroxybenzoate forms a similar liquid-crystalline phase, with the guest included in the core of the assemblies.
