Carboxyl end-groups as a starting point for chemical modifications : COO - : COOH 2. step: Conversion of the carboxyl groups to the corresponding acid chloride by refluxing in thionyl chloride R-COOH + SOCl 2 → R-COCl + SO 2 + HCl The chlorine group is very reactive and allows versatile modification
Test experiment: Attachment of molecular linkers • Allows end-to-side as well as end-to-end interconnections • linker: alkane chain
