In recent past years, investigation of hierarchical self-assembly for constructing artificial functional materials has attracted considerable attention. Discrete metallacycles based on coordination bonds have proven to be valid scaffolds fabricate various supramolecular polymers or smart soft matter through self-assembly. Here, we present the first example discrete by taking advantage positive charges organoplatinum(II) metallacycle skeleton multiple electrostatic interactions. Heparin, a...
The design and self-assembly of novel multipyrene hexagonal metallacycles via coordination-driven is described. By employing newly designed 120° dipyridine donor di-Pt(II) acceptor linkers substituted with pyrene, a variety tris- hexakis(pyrene) well-defined shape size were prepared [3 + 3] [6 6] self-assembly, respectively, under mild conditions in high yields. structures these well characterized by multinuclear NMR (31P 1H) spectroscopy, cold-spray ionization time-of-flight mass...
A discrete hexagonal metallacycle decorated with multiple amide groups and long hydrophobic alkyl chains was constructed via [3+3] coordination-driven self-assembly, from which the ordered nanofibers stimuli-responsive supramolecular gels were successfully obtained hierarchical self-assembly.
Cyclic processes involving medium-sized rings show low rates because internal strains-torsions and transannular interactions-are created during the reactions. High dilution is often used to slow competing bi- higher-molecular but cannot accelerate desired cyclization reaction. Here we apply cavitands formation of medium- large-sized through conversion long-chain diisocyanates cyclic ureas. The reactions take place in aqueous (D2O) solution, where hydrophobic forces drive starting materials...
The synthesis of a series platinum acetylide derivatives, featuring linear, triangular, and rectangular shapes, respectively, is described. structures these complexes were characterized by multinuclear NMR (1H, 13C, 31P), CSI-TOF mass spectrometry, elemental analysis. It was found that exhibited unexpectedly different gel formation properties in the most common organic solvents. Moreover, organometallic gels C1 C2 concentration- temperature-dependent emission properties.
Described herein is the behavior of α,ω-dienes sequestered within cavitands in aqueous (D2 O) solution. Hydrophobic forces drive dienes into conformations that best fill available space. Shorter (C9 and C10) bind compressed tumble rapidly cavitands. Longer induce capsule formation between with self-complementary hydrogen bonding sites, where exist extended conformations. In unable to form capsules, longer adopt folded structures. The wider open ends allow synthesis medium-sized cycloalkenes...
A new family of platinum acetylide derivatives containing iptycene building blocks end-capped with 3,4,5-tris(alkoxy)phenyl substituents has been successfully synthesized. The structure the newly designed complexes was characterized by multinuclear NMR (1H, 31P, and 13C) mass spectroscopy elemental analysis. Unexpectedly, all compounds presented good gel formation properties in some common organic solvents. morphology xerogels investigated scanning electron microscopy (SEM). An investigation...
A neutral branched platinum–acetylide complex <bold>TPA</bold> possessing a tetraphenylethylene core was successfully prepared, which found to form luminescent organometallic gels in ethyl acetate.
We describe herein the hierarchical self-assembly of discrete supramolecular metallacycles into ordered fibers or spherical particles through multiple noncovalent interactions. A new series well-defined decorated with long alkyl chains were obtained metal-ligand interactions, which capable aggregating fibroid nanostructures on surface, mostly driven by hydrophobic In-depth studies indicated that morphology diversity was originated from structural information encoded in metallacycles,...
A series of new ethynyl-pyrene modified platinum-acetylide gelators were prepared, some which found to be able incorporate graphene into the metallogel matrix.
A new branched platinum–acetylide complex PP6 containing pyrene as the main skeleton, pentiptycene units bridges, and long alkyl chains branches was successfully synthesized. The structure of well characterized by 1H NMR, 31P {1H} MALDI-TOF-MS spectrometry, semiempirical PM6 method. investigation absorption emission spectra model complexes revealed that introduction iptycene beneficial to improve efficiency. More importantly, aggregated into ordered microspheres driven...
Abstract Described herein is the behavior of α,ω‐dienes sequestered within cavitands in aqueous (D 2 O) solution. Hydrophobic forces drive dienes into conformations that best fill available space. Shorter (C9 and C10) bind compressed tumble rapidly cavitands. Longer induce capsule formation between with self‐complementary hydrogen bonding sites, where exist extended conformations. In unable to form capsules, longer adopt folded structures. The wider open ends allow synthesis medium‐sized...
