Forming ferrocenyl self‐assembled monolayers on Si(100) electrodes with different alkyl chain lengths for electron transfer studies

The reaction of hydrogen-terminated Si(100) with 1,8-nonadiyne was previously shown to afford robust surfaces where oxidation of the substrate is not evident. Here, the experimental conditions required for reacting hydrogen-terminated Si(100) with α,ω-diynes of different lengths is explored via ther...
