The Construction of Multichromophoric Assemblages: A Booming Field

Abstract: The field of molecular photonics has witnessed significant advancements in the construction of multichromophoric assemblages, which play a crucial role in guiding and manipulating light energy at the molecular level. This paper provides an overview of the strategies and techniques employed in the design and synthesis of such assemblies, with a focus on covalent buildings. The concept of molecular photonic wires is introduced, where chromophores passively guide excitations between functional units. Various examples of covalent structures, including multiporphyrinic architectures, are presented, demonstrating precise control over energy transfer and propagation. Additionally, the polymerization of rigid porphyrinic precursors is explored as an alternative approach. The challenges and potential applications of these multichromophoric assemblies in the field of molecular photonics are discussed. The study highlights the importance of understanding the interactions between chromophores and offers insights into the applicative potential of organic compounds for emerging technologies.
