Stability of hexa(ethylene glycol) SAMs towards the exposure to natural light and repeated reimmersion

Abstract:

We investigate the stability of HS(CH 2) 11(OCH 2CH 2) 6CH 3 self assembling monolayers (hexa(ethylene glycol) SAMs) on gold regarding reimmersion and exposure to natural light over long periods of time up to several months. With polarisation modulation infrared spectroscopy we were able to monitor significant changes in the fingerprint region (900-1800 cm -1) of the absorption modes of the SAMs, starting after a few days of exposure to natural light. We observed an exponential intensity decr...
