Coordinative Supramolecular Assembly of Electrochromic Films Based on Metal Ion Complexes of Polyiminofluorene with Terpyridine Substituent Groups

Abstract: The formation and characteristic properties of organized films that are based on metal ion complexes of poly(4-(2,2 0 :6,2 00 -terpyridyl)phenyliminofluorene) (P1) with thickness control in the nanometer range are reported. The films were obtained upon multiple sequential assembly of divalent metal ions (Zn, Co, Ni) and the terpyridine(tpy)-substituted polymer P1 on solid supports via coordinative interactions between metal ions and tpy ligands. The influence of deposition parameters is described, and the opti… Show more

“…The switching time, at an applied potential of 0.56 V, was about 0.45 s which is faster than the ones obtained for electrostatic electrochromic LbL films. A quasi-reversible change was obtained with different colors depending on the ions used, with an optical contrast of 18% [79,80]. This value is comparable to electrostatic LbL films with the same number of layers [78].…”

“…Later, Maier et al used polyiminoarylene functionalized with terpyridine moieties and assembled by coordination through zinc hexafluorophosphate (ZnPF 6 ) in an organic solvent (Fig. 4b) [79]. The stable arylene units and easily oxidizable amine groups resulted in electrochromic properties while terpyridine substituent groups allowed coordinative self-assembly with metal ions.…”

“…The solvent was then removed and the residue was redissolved in CHCl 3 , washed with a sat. NH 4 Cl solution and water, dried with MgSO 4 and the solution concentrated. In the case of aryl halides 4 and 5 a larger excess (15 mmol) was used to avoid polycondensation.…”

“…[1,2] Oligopyridyl ligands and their transition-metal complexes, which have found applications in several areas of modern research, are examples of such systems. [3][4][5][6][7][8][9][10][11][12][13] 2,2Ј:6Ј,2ЈЈ-Terpyridines bearing well-defined π-conjugated substituents at the 4Ј-position are known to exhibit attractive electronic and optical properties. [6,8,10,[14][15][16][17][18][19][20][21][22][23][24][25] When two 2,2Ј:6Ј,2ЈЈ-terpyridine units are introduced at either end of a rigid conjugated spacer, the resulting ditopic bis(terpyridine) ligand enables the synthesis of metallo-supramolecular polymers by coordination with different metal ions.…”
