Innovative 2D Molecular Assemblies Enhance Solar Cell Efficiency

Researchers develop triptycene-based scaffolds to facilitate efficient singlet fission in pentacene, boosting charge carrier generation.

A new study introduces tripodal triptycene scaffolds that enable the assembly of diverse 2D molecular structures.
These scaffolds can organize acene chromophores, crucial for singlet fission, into efficient configurations.
Pentacene-based assemblies achieved an 88% quantum yield for generating triplet pairs and 130% for free triplets.
The adaptable scaffold design offers a versatile platform for constructing 2D assemblies with various molecules.
This breakthrough has significant implications for advancements in materials science, organic electronics, and solar cell technology.
