ATP as Building Blocks for the Self-Assembly of Excitonic Nanowires

摘要

We describe herein self-assembly of adenosine 5'-triphosphate(ATP)and dichloro-substituted thiacarbocyanine dyes into ther-mochromic supramolecular nanowires.Excitonic interactions among chromophores aligned in the nanowires and their reversible dissociation/reassembly characteristics render them a new family of biomolecules-based nanowire systems.Integration of biologically important small molecules and functional organic molecules provides access to supramolecular nano-architectures that are capable of converting biomolecular structural information to physicochemical signals.However,to date,studies on self-assembly of biological molecules have been focused on large biopolymers such as proteins,oligopeptides,and nucleic acids.
