摘要：

Alignment of cationic donor-(pi-bridge)-acceptor molecules via metathesis with a self-assembled monolayer formed from sodium 3-mercapto-1-propanesulfonate results in ultra-thin rectifying Au-S-(CH2)(3)SO3-vertical bar A(+)-pi-D structures which exhibit optimum current ratios of 450 at +/- 1 V for N-methyl-5-(4dibutylaminobenzylidene)-5,6,7,8-tetrahydroisoquinolinium.
