The chemical structure of the Cn HATs is very similar to that of C6 HAT reported before. An alkyl thiolate linker of various lengths ranging from 0.7 nm to 1.7 nm was attached to the ester moiety of a hydrazone skeleton , which has a thermal half-life of 255 years in toluene. The synthetic approach followed a procedure reported in the literature, with yields between 51-78 %. Products were characterized using NMR spectroscopy (Figures ) and high-resolution mass spectrometry. The corresponding bromine terminated model compounds (Cn Br) were also synthesized and characterized (Figures ).
