<br/><br/> 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.
