Replacing −CH2CH2– with −CONH– Does Not Significantly Change Rates of Charge Transport through AgTS-SAM//Ga2O3/EGaIn Junctions
摘要:
This paper describes physical-organic studies of charge transport by tunneling through self-assembled monolayers (SAMs), based on systematic variations of the structure of the molecules constituting the SAM. Replacing a -CH2CH2- group with a -CONH- group changes the dipole moment and polarizability of a portion of the molecule and has, in principle, the potential to change the rate of charge transport through the SAM. In practice, this substitution produces no significant change in the rate of charge transport across junctions of the structure Ag-TS-S(CH2)(m)X(CH2)(n)H//Ga2O3/EGaIn (TS = template stripped, X = -CH2CH2- or -CONH-, and EGaIn = eutectic alloy of gallium and indium). Incorporation of the amide group does, however, increase the yields of working (non-shorting) junctions (when compared to n-alkanethiolates of the same length). These results suggest that synthetic schemes that combine a thiol group on one end of a molecule with a group, R, to be tested, on the other (e.g., HS similar to CONH similar to R) using an amide-based coupling provide practical routes to molecules useful in studies of molecular electronics.

Metallations of NN-dimethyl-linoleamine were also obtained. The positions of carbonation of these lithium derivatives revealed a long-range effect of the functional groups.

We report the synthesis of 7alpha-substituted beta-estradiol derivatives bearing side chains terminated with cholesterol and 3beta-cholesterylamine. These chimeric compounds were designed to exhibit high affinity for estrogen receptors (ERs) and cellular plasma membranes to potentially enable regulated uptake of ERs by mammalian cells. Evaluation with recombinant yeast reporting compound-mediated ER dimerization revealed potencies similar to the antiestrogen ICI 182780. Compounds that efficiently deliver dominant negative ERs into cells may provide novel therapeutics against breast cancers.
