SAMs pyridine-terminated

Since the amino- and pyridine-terminated monolayers were considered optimal, four additional molecules (6-9) were synthesised based on the assumption that an extension of the aromatic system would result in better ordered monolayers. In addition, these molecules might even show the semiconducting properties required for the successful fabrication of SAM-based OFETs. The respective monolayers were again deposited from EtOH and THF the resulting layer thicknesses have already been given in Table 7.1. For these SAMs, we used the established sulfite/hydroxylamine bath and restricted ourselves to the use of the citrate-NPs and MEE-NPs, because these nanoparticles were the most stable ones and, in addition, most often resulted in selective depositions. 

An electrochemical inclusion junction has also been described [118, 119]. It consists of two HMDEs, both of which support a SAM of the ruthenium pentamine pyridine-terminated thiol, HS(CH2)ioCONHCH2pyRu(NH3)s, and are brought into contact in an aqueous solution. The potentials of the two electrodes are controlled independently with respect to a common reference electrode immersed in the solution, by using a bipotentiostat. Under certain... 

Fig. 16 Schematic coupling model of the photo-switchable interactions between cytochrome c and the mixed SAM of spiropyran/merocyanine-terminated and 4-pyridine thiol with (a) the reduction of O2 by COx and (c) the oxidation of lactate by lactate dehydrogenase (LDH). (b) When the electrode is in the cationic merocyanine state, repulsive interactions disallow the functioning of the bioelectrocatalytic processes [130].
