The chair conformation of C-methylcalix[4]resorcinarene in a novel, stepped, supramolecular framework
The previously unobserved chair conformation of C-methylcalix[4]resorcinarene has been found in three different supramolecular solids, prepared by hydrothermal synthesis. The existence of the chair, crown and flattened cone conformations of C-methylcalix[4]resorcinarene demonstrates the dependence of the molecular conformation upon the templating molecules, and upon the specifics of the crystal...
متن کاملC-Methylcalix[4]resorcinarene–1,4-bis(pyridin-3-yl)-2,3-diaza-1,3-butadiene (1/2)
In the title compound, 2C(12)H(10)N(4)·C(32)H(32)O(8), the calixarene adopts a rctt conformation with dihedral angles of 138.40 (1) and 9.10 (1)° between the opposite rings. The dihedral angles between the rings of the pyridine derivative are 8.80 (1) and 9.20 (1)°. In the crystal, adjacent C-methylcalix[4]resorcinarene molecules are connected into columns parallel to [010] by O-H⋯O hydrogen bo...
متن کاملTransformation of a C-methylcalix[4]resorcinarene-based host-guest complex from a wave-like to a novel triangular brick-wall architecture.
A novel 2D triangular brick-wall framework based on CMCR and bpe with included ruthenocene guest molecules is formed with time by conversion of a 1D wave-like polymer structure with an accompanying bowl-to-boat conformational change of the CMCR molecules.
متن کاملStructure and photoluminescence of a benzil nanocolumn in a C-methylcalix[4]resorcinarene-based framework.
A new framework based on C-methylcalix[4]resorcinarene and the flexible nonconjugated spacer 1,4-bis(imidazol-1yl-methyl)benzene encloses a large one-dimensional channel, containing benzil nanocolumns. Unlike in a previously reported series of benzil-containing supramolecular solids with conjugated linker molecules, benzil luminescence is observed, but the lifetime of 580 ns at 77 K is consider...
