Electrode-solution interface supramolecular

The successful trapping and subsequent immobilization of the 2-1" inclusion complex on gold surfaces demonstrates that the ideas and concepts common to the fields of molecular recognition and supramolecular chemistry can also be utilized to assemble novel structures at the electrode-solution interface. 

The nature of the platform also impacts on the electrochemical and photophysical properties of the interfacial supramolecular assembly (ISA). For example, the density of states within gold, platinum and carbon electrodes are different, so causing subtle changes in the rate of electron transfer across the electrode/ISA interface. In addition, in terms of the photophysical properties, the nature of the platform can radically change the excited-state properties of a molecule upon adsorption. For example, if a adsorbate is located close to (<10 nm) a metal surface and is then pumped into an electronically excited state, efficient energy or electron transfer is expected which will lead to quenching of the excited state. This process can dramatically increase the photostability of compounds that would ordinarily photodecompose in solution.
