Sol-Gel Reaction of Porphyrin-Based Superstructures in the Organogel Phase:Creation of Mechanically Reinforced Porphyrin Hybrids

摘要

It is well-known that porphyrins and phthalocyanines tend to align into one-dimensional aggregates and,therefore,are of much concern in relation to the creation of novel supramolecular architectures,such as nanowires,discotic liquid crystals,helical ribbon structures,etc.The major driving forces operating in these architectures are considered to be pi-pi stacking and/or van der Waals interactions.It is possible to fabricate these one-dimensional aggregates by inorganic materials,utilizing electrostatic and/or hydrogen-bonding interactions,to produce novel fibrous organic-inorganic hybrid materials.
