Facile Preparation of a Fully π‐Conjugated Metallopolymer Composed of Fused Salphen Complexes

Abstract

Novel π-conjugated compounds composed of fused salphen groups as a repeating unit, embedded with four or an indefinite number of zinc nuclei have been synthesized. The solid-state absorption spectra, IR spectra, and powder XRD patterns of these compounds are investigated and compared with those of analogous oligomers. The presumptive polymer contains at least five units of the salphen complex and its assembly is highly ordered in the solid state.

Rigid chain ribbon‐like metallopolymers

“…In Figure 1, the FTIR spectra of the two homopolymers P0-Cu and P100-Cu, along with that of P50-Cu, are reported. In all the presented spectra, it is possible to identify the signals distinguishing the CAH stretching (at around 2920 and 2850 cm 21 ) and the imine C@N stretching (at around 1610 cm 21 ); in the spectra of P0-Cu and P50-Cu, moreover, other two significant signals are observed: in particular, carbonyl stretching at 1720 cm 21 and ester CAO stretching at 1255 cm 21 , associable to the flexible repeating units deriving from P12-8N, appear, while they are absent in the spectra of the fully rigid P100-Cu.…”

“…19,20 As already proposed, this kind of systems can be considered the ultimate organic-inorganic hybrids, in which the two components are mixed at a molecular level. 21 They have been deeply investigated for what concerns their electrical properties (for application in photovoltaics 22,23 and sensors 24,25 ), their electroluminescence activity, 26,27 their NLO properties [28][29][30] and liquid crystalline behavior. 31 Regarding the nature of the organic ligands, Schiff-bases have been widely investigated in the literature for the preparation of interesting metallo type assemblies, mainly because of their versatility, structural variety, and ease of preparation.…”

Characterization of Π-conjugated metallopolymer's mechanical stiffness by using silicon nanotweezers

“…The monomer compound (amino-aldehyde, Figure 3) was prepared according to the reported method [8]. To form the monomer wire at the tips, we use a surface combing technique.…”

Palladium-containing polymers via a combination of RAFT and triazole chemistry

“…12 Depending on the preferred coordination mode and number of the metal ions, linear, dendritic or starshaped metallosupramolecular polymers are accessible. by polyaddition or polycondensation reactions, 15 or attached to the side chains of a polymer. 14 On the other hand, suitable entities can be integrated in polymers by covalent linkages, either directly onto the main chain, e.g.…”
