In this letter, we describe the iterative solution phase synthesis of a triarylamine trimer as proof of concept towards the synthesis of oligomeric materials by solid-phase synthesis. Our model system utilises the stability of germanium linkers to nucleophilic conditions to develop efficient steps towards oligomer synthesis via (i) selective deprotection of tert-butyl-dimethyl-silyl ether (OTBDMS) functionality, (ii) conversion to reactive trifluoromethanesulfonate (triflate) functionality and (iii) Suzuki cross-coupling reactions.
