Summary
Introducing conjugated cross-links in polymers enhances charge transport. This review covers synthesis, processing, and properties of these networks, highlighting benefits for electrical conductivity when polymers are carefully designed.
Area of Science:
- Chemistry
- Materials Science
- Physics
Background:
- Conjugated polymers are widely researched, but conjugated cross-links are overlooked.
- Introducing cross-links is challenging due to processability issues.
Purpose of the Study:
- To provide an overview of conjugated polymer networks with cross-links.
- To discuss synthesis, processing, and electronic properties.
- To highlight recent studies with charge transport or conductivity data.
Main Methods:
- Review of recent studies on conjugated polymer networks.
- Separate analysis of covalent cross-links and non-covalent organometallic bridges.
- Focus on materials with available charge transport or electrical conductivity data.
Main Results:
- Cross-linking can significantly improve intermolecular charge transfer.
- Careful polymer design is crucial for realizing benefits.
- Two architectures are discussed: covalent and non-covalent cross-links.
Conclusions:
- Conjugated cross-links offer potential for enhanced electronic communication in polymers.
- Processability and design are key factors for successful implementation.
- Further research into these networks can advance polymer conductivity.
