WebIn this manuscript, after the detailed explanation of the CD-RAS technique, some calibration tests with chiral porphyrin assemblies in solution or deposited in solid film are reported to demonstrate the quality of the results, comparing curves obtained with CD-RAS and a commercial spectrometer. Reflectance anisotropy spectroscopy (RAS) has been ... WebAug 1, 2012 · The self-assembly in this condition resulted the noncovalent synthesis of 2-dimensional or 3-dimensional multiporphyrin assemblies and remarkable stability of these assemblies permitted a stepwise synthesis that makes it possible to choose the desired porphyrin sequence.

WebMolecular assemblies of two achiral porphyrins with different substituents, 5-(4-methoxycarbonylphenyl)-10,15,20-triphenyl-21H,23H-porphine (TPPCOOMe) and 5-(4-carboxyphenyl)-10,15,20-triphenyl-21H,23H-porphine (TPPCOOH), have been fabricated by the Langmuir–Blodgett (LB) technique. It is disclosed that although only slight differences … WebJan 20, 2024 · Supramolecular self-assembly shows a way to construct chiral materials by self-assembling simple molecules into chiral composites. Herein, we demonstrate the … WebThe deposition of molecules onto surfaces from dilute solutions can lead to a variety of layer morphologies depending on the balance of interactions between solvent and molecule, molecules themselves, and these two components and the surface. Here we explore the behaviour of a set of chiral tetra meso-amidophenyl-substituted porphyrins—containing … flow mega
