摘要

A ligand-directed strategy was implemented: electrosynthesizing two metallopolymers from a tetradentate

planar tpz monomer (R

) and a tridentate bpp monomer (R

) to study the differences in electrical conductivity and memristive performance.

Abstract

D-

hybridization is a key structural feature that may significantly affect the intrinsic electronic properties of metallopolymers. Herein

we present the electrosynthesis and memristive properties of metallopolymers using the distinct d-

hybridization monomers R

and R

. R

(Ru

-(tpz)Cl

) features tetradentate ligands (tpz

6'-di(1

-pyrazol-1-yl)-2

2'-bipyridine) enforcing quasi-octahedral geometry; R

(Ru

-(bpp)

) incorporates tridentate ligands (bpp

6-di(1

-pyrazol-1-yl)pyridine) inducing pronounced geometric distortion. The planar ligand (tpz) in R

facilitates ordered molecular assembly through high conformational rigidity and extensive

stacking

resulting in increased molecular densities and enhanced morphological uniformity compared to R

metallopolymers. Due to pyrazole’s weaker

-acceptance and st

ronger

-donation compared to pyridine

exhibits a 119 nm red-shift in metal-to-ligand charge transfer (MLCT) band and a 30 mV anodic shift in Ru

+2/+3

redox potential relative to R

. Coupled with a reduced HOMO–LUMO gap

the uniform and ordered structure leads to a lower conductance decay constant in R

. Additionally

metallopolymers exhibit superior memristive performance (characterized by lower switching voltage and higher switching ratio)

via

redox-induced aromatic transitions in axial ligands enhancing electronic delocalization. This work compares two metallopolymers with different ligand geometries

revealing how this difference leads to distinct charge transport and memristive behaviors.
