Transformation of a C-methylcalix[4]resorcinarene-based host-guest complex from a wave-like to a novel triangular brick-wall architecture.
نویسندگان
چکیده
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.

Six supramolecular complexes incorporating benzil as a guest, CMCR*bipy*benzil (alpha) 1 (CMCR = C-methylcalix[4]resorcinarene), CMCR*bipy*benzil (beta) 2, CMCR*2bpe*benzil*ethanol 3 (bpe = trans-1,4-bis(pyridyl)ethylene), CMCR*2bpe*benzil*2H2O 4, CMCR.2bpeh*benzil*ethanol 5 (bpeh = bis-(1-pyridin-4-yl-ethylidene)-hydrazine), and CECR*2bpe.benzil 6 (CECR = C-ethylcalix[4]resorcinarene), have be...
متن کاملThe 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 کاملPaper Emission quenching of photoactive molecules embedded in supramolecular solids: Synthesis, structure and photoluminescence studies of benzil in a CMCR-based inclusion complex with a saturated linker molecule{
Using a fully saturated linker, DPP [DPP ~ 1,3-di-(4-piperidyl)propane], a new CMCR-based (CMCR ~ C-methylcalix[4]resorcinarene) supramolecular complex incorporating benzil, CMCR-DPP-benzilEtOH-H2O, and a corresponding benzil-free analogue CMCR-DPP-3EtOH, have been synthesized. Comparison of the TDDFT energy levels and the experimental host-absorption and guest-emission spectra, confirms that t...
متن کاملA novel scoop-shaped conformation of C-methylcalix[4]resorcinarene in a bilayer structure.
A new scoop-shaped conformation of C-methylcalix[4]resorcinarene has been identified; it is a hybrid of the previously observed crown- and flattened cone conformations.
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...
