Abstract
The present invention relates to modified surfaces. The surfaces comprise an inorganic material on which a phosphinic acid derivative is adsorbed. The phosphinic acid thus turns out to be a new anchoring group useful for surface derivatization. The invention has many applications for photoelectric conversion devices, batteries, capacitors, electrochromic displays, chemical sensors, biological sensors, light emitting diodes, electrodes, semiconductors, separation membranes, selective adsorbents, adsorbents for HPLC, catalysts, implants, nanoparticles, antiadhesives, and anticorrosion coatings, for example.
