AbstractA series of phosphorescent terpyridyl platinum(II) complexes with ancillary biphenylacetylide ligands, namely, [(R 3tpy)PtC≡C(biphenyl)]X (R=tBu, H, or Et 2N; tpy=2,2'6',2'-terpyridyl; X is an anion) were synthesized and structurally characterized by various spectroscopic techniques and X-ray diffraction methods. Despite a lack of long alkyl chain(s) or hydrogen-bonding motif(s), complexes [(tpy)PtC≡C(biphenyl)]Cl and [(tBu 3tpy)PtC≡C(biphenyl)]X (X=Cl, ClO 4, PF 6, or BF 4) were found to gelate water and organic solvents, respectively. The self-aggregation of these complexes in solutions and the resulting gels were investigated with variable-temperature (VT) 1H NMR spectroscopy, polarized optical microscopy, and absorption/emission spectroscopy. SEM micrographs on dry gels revealed entangled nanofibers with diameters of 20-40 nm and lengths of tens of micrometers. Powder X-ray diffraction (PXRD) study revealed various degrees of crystallinity of these fibrillar nanostructures. The substituents on both the terpyridyl and acetylide ligands and counterion of these complexes play a profound but concerted role in tuning the intermolecular metal⋯metal and/or π-π interactions, and hence the gelation properties. © 2011 WILEY-VCH Verlag GmbH & Co.
