Porphyrin based molecular turnstiles.
Molecular turnstiles, based on a hinge composed of a Sn-porphyrin bearing coordinating sites at the meso positions and a handle, equipped with a tridentate coordinating pole or its Pd(ii) complex, connected to the porphyrin through Sn-O bonds, offering open (free rotation of the handle around the hinge) and close states (blockage of rotation through binding of Pd(ii)) were designed, prepared an...
متن کاملMolecular porphyrin – fullerene architectures *
This article describes the utilization of porphyrin and fullerene architectures— yielding artificial light-harvesting antenna and reaction center mimics—to tune the electronic coupling element between electron donor and electron acceptor and ultimately to affect the total reorganization energy. Most importantly, the effects that these parameters have on the rate, yield, and lifetime of the ener...
متن کاملMolecular tailoring of interfacial failure.
Self-assembled monolayers (SAMs) provide an enabling platform for molecular tailoring of the chemical and physical properties of an interface. In this work, we systematically vary SAM end-group functionality and quantify the corresponding effect on interfacial failure between a transfer printed gold (Au) film and a fused silica substrate. SAMs with four different end groups are investigated: 11...
متن کاملEnantioselective recognition by a highly ordered porphyrin-assembly on a chiral molecular gel.
Enantioselective recognition of amino acids was achieved by using a highly ordered chiral assembly of achiral porphyrin on a chiral molecular gel. Exceptionally high enantioselectivity was observed for histidine derivatives by monitoring the CD patterns and fluorescence quenching, K(SV) (l): 26.3 × 10(3) M(-1); K(SV)(D)-enantiomer: 7.03 × 10(3) M(-1).
متن کاملAb initio study on the molecular recognition by metalloporphyrins: CO interaction with iron porphyrin
We have performed ab initio pseudopotential calculations to study the effects of structural deformations of iron porphyrin on the configuration of a carbon monoxide ~CO! attached to it. We have considered two proximal deformations around the heme group: ~i! rotation of a pyrrole ring in the iron porphyrin, and ~ii! rotation of the imidazole side chain bound to the iron atom. We have identified ...
