The synthesis of the 1,3,5-tris[(diphenylphosphoryl)alkyl]-benzenes 7-10 succeeds by reaction of the corresponding 1,3,5-tris(bromoalkyl)benzenes 3-6 with ethyl diphenylphosphinite in an Arbusov-type reaction. Reduction of these phosphane oxides leads to the trifunctional phosphane ligands 11-14. Their potency of self-assembly was examined by the employment of platinum(II) complex fragments. A five-component self-assembly consisting of 3 equiv, of the platinum complex Cl2Pt(NCPh)2 and 2 equiv, of the ligands 11-14 under high-dilution conditions led to the formation of the nanoscaled triplatinacyclophanes 1 and 15-17. Polymers were formed as by-products from the reactions between 11-13 and Cl2Pt(NCPh)2, whereas in the case of 14 three other platinacyles 18-20 with a chain-like structure were formed. The structures of the metallacycles 1 and 15-17 as well as 18-20 were elucidated by 31p{1H}, 13C{1H}, and 195Pt{1H} NMR spectroscopic investigations.

Synthesis of 1,3,5-tris(4′-bromobutyl)benzene has been achieved by means of two step reaction. This compound reacts with ethyl diphenylphosphonic ester to form phosphoryl oxide which transformed to tertiary phosphine ligand. Employing the high dilution method from the ligand and Cl2Pt(NCPh)2 a cage compound is formed.
