Concerted motions in supramolecular systems: metal-mediated assemblies of porphyrins that behave like nanometric step-machines.
نویسندگان
چکیده
According to NMR evidence the metal-mediated sandwich assemblies of porphyrins 2 and 3 undergo in solution a thermally driven motion that resembles that of a stepper: the spontaneous rotational motion of the pyridyl rings is converted into a reciprocating linear motion of the porphyrins.

Preparation and structural control of metal coordination-assisted supramolecular architectures of porphyrins. Nanocubes to microrods.
We have successfully prepared metal coordination-assisted porphyrin assemblies such as nanocubes, nanorods and microrods by controlling the synthetic conditions. The internal structures and lifetimes of the excited states are also quantitatively discussed.
متن کاملInterfacial assemblies of atypical amphiphilic porphyrins: hydrophobicity/hydrophilicity of substituents, annealing effects, and supramolecular chirality.
Interfacial molecular assemblies of eight atypical amphiphilic porphyrins, substituted with hydrophobic or hydrophilic substituents but without long alkyl chains on their molecular skeletons, have been investigated in terms of supramolecular chiralty generation and amplification. It is found that all of the originally organized interfacial molecular assemblies display very weak or undetectable ...
متن کاملTwo coordinatively linked supramolecular assemblies constructed from highly electron deficient porphyrins
The synthesis of a pair of electron-deficient porphyrin building blocks and their resulting coordinatively linked supramolecular assemblies are described. The perfluorophenyl substituted porphyrins feature pendant pyridines which, upon reaction with Re(CO)5Cl assemble into discrete dimers and tetramers, as dictated by the geometry of the porphyrin monomer. The resulting supramolecular complexes...
متن کاملSelf-organization of Short Peptide Fragments: From Amyloid Fibrils to Nanoscale Supramolecular Assemblies
Numerous supramolecular protein assemblies had been demonstrated to have either physiological or pathological activities. The most significant case of diseaseassociated self-organized structures is that of amyloid fibrils. The formation of these fibrils is the hallmark of major human disorders, including Alzheimer’s disease and type II diabetes. In this review we illustrate the molecular proper...
متن کاملReprogramming an ATP-driven protein machine into a light-gated nanocage
Natural protein assemblies have many sophisticated architectures and functions, creating nanoscale storage containers, motors and pumps. Inspired by these systems, protein monomers have been engineered to self-assemble into supramolecular architectures including symmetrical, metal-templated and cage-like structures. The complexity of protein machines, however, has made it difficult to create as...
