Summary
Ruthenium(II) metallo-polymers were synthesized as high molar mass materials. However, their application in bulk-heterojunction solar cells yielded low efficiencies due to morphology issues.
Area of Science:
- Materials Science
- Polymer Chemistry
- Photovoltaics
Background:
- Metallo-polymers are advanced materials with tunable electronic and optical properties.
- π-conjugated polymers are crucial for organic electronics applications.
Purpose of the Study:
- Synthesize and characterize novel zinc(II)- and ruthenium(II)-containing π-conjugated metallo-polymers.
- Investigate the properties of these polymers in thin films and their performance in solar cells.
Main Methods:
- Synthesis and detailed characterization of metallo-polymers.
- Size exclusion chromatography (SEC), analytical ultracentrifugation (AUC), and viscosimetry for molar mass determination.
- Spin-coating for film preparation and photophysical property investigation.
Main Results:
- Ruthenium(II) metallo-polymers were confirmed as high molar mass materials (M(fs) = 20,000–34,000 g·mol⁻¹) with high intrinsic viscosities (up to 192 cm³·g⁻¹).
- Homogeneous polymer films were produced via spin-coating.
- Incorporation into bulk-heterojunction solar cells with PCBM[60] resulted in poor device efficiencies.
Conclusions:
- The synthesized ruthenium(II) metallo-polymers exhibit desirable characteristics for material applications.
- Morphology challenges in bulk-heterojunction solar cells limit the efficiency of these metallo-polymers in photovoltaic devices.

02:51Metal-Ligand Bonds
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

01:19Complexation Equilibria: The Chelate Effect
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...
00:53Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)
Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

01:13Olefin Metathesis Polymerization: Overview
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.

01:20Anionic Chain-Growth Polymerization: Overview
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...
00:43Complexometric Titration: Ligands
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...
