Abstract

A self assembling method based on osmotic procedure allowed fabricating nanostructured aggregates of dinuclear complexes made of Zn-porphyrin bridges between Pt(II) acetylide tethers. The choice of experimental parameters, such as solvent/non solvent couple and temperature allows achieving nanostructures that look like rod-like crystals and spheres, the latter ones showing either solid or concave internal structures. The porphyrin bridged di-bis(triphenylphosphine)platinum phenylacetylide, porphyrin bridged di-bis(triphenylphosphine) platinum p-nitrophenylacetylide and porphyrin bridged di-bis(triphenylphosphine)platinum p-methoxyphenylacetylide, were synthesized by the coupling of 2,8,12,18-tetraethyl-5,15-diethynyl-3,7,13,17-tetramethylporphyrinatozinc(II) with the corresponding trans-[Pt(PPh(3))(2)(C C-R)CI] complexes (R = C(6)H(5), C(6)H(4)NO(2), C(6)H(4)OCH(3)). The molecular structures were assessed with NMR and ToF-SIMS studies and the nanostructure formation was revealed with SEM investigations. The results could be of interest for future applications in optoelectronic devices, sensors, biotechnology and light harvesting. (C) 2008 Elsevier B.V. All rights reserved.
