We report the synthesis of novel soluble ditopic terpyridine ligands bearing an alternance of acetylenic/phenyl modules (one to five) built in the centre. The protocol is based on sequential Pd-promoted cross-coupling reaction between selected mono-terpy fragments and either mono-protected 1,4-diethynyl-2,5-di(dodecyloxy)benzene or 1,4-diethynyl-2,5-di(dodecyloxy)benzene synthons. The ligand bearing
