All chemicals were purchased from Fisher, Fluorochem and Sigma Aldrich and were used as obtained unless otherwise stated. Solvents were dried over 3 Å molecular sieves, whereas glassware and stir bars were dried in oven overnight at 100 °C. Sbenzyl-S'-propyl carbonotrithioate and S-benzyl-N,N-diethyl dithiocarbamate were synthesised following literature procedures. 1,2,3,4,5-Pentakis(carbomethoxy)cyclopentadiene (PCCP) was synthesised following the method reported by M. A. Radtke et al. The monomer DOT was synthesised as described by Bingham et al. For the purification of the products by column chromatography, Sigma silica gel Geduran Si60 (40-63 μm) was used.
