“…In fact, metal ions were not necessary to construct novel conjugated main chains. A recent study described the synthesis of various conjugated polymers containing only tpy segments, in which tpy-substituted carbazole (TPCz) was used as the electron donor, followed by the fabrication and evaluation of photovoltaic cells (Wang et al, 2020 ).…”

2,2′:6′,2″-Terpyridine (tpy) is a versatile moiety used in the construction of small novel molecules or polymers. Extending or coupling tpy with π-conjugation structures can result in interesting optoelectronic properties. This mini-review summarizes the significant progress made over the past decades in the study of tpy-containing π-conjugated polymers and their application in light-emitting and photovoltaic materials. When coordinated with metal ions, tpy exhibits immense potential for the synthesis of metallo-supramolecular or metallo-polymer materials. Therefore, tpy-based metallo-polymers are the primary focus of this study. Selected examples will be reviewed with a special emphasis on the properties of these functional systems, which can consequently help further their application in light-to-electricity or electricity-to-light conversion fields.

“…The utilization of noncovalent interactions in dye-based materials has been shown to be a promising strategy for the fabrication of organic electronics. − The photophysical, optoelectronic, and thermomechanical properties of materials are not only dependent on the chemical structure but also on the self-assembly of the molecules in both solution and the solid state. − Since noncovalent interactions can be tailored and designed to be highly specific, supramolecular chemistry has allowed for the development of novel dye-based materials with favorable optoelectronic properties. Specifically, the incorporation of noncovalent bonding moieties in DPP-based π-conjugated polymers through either backbone or side-chain engineering has allowed for new materials with improved charge transport and thermomechanical properties. − However, the use of supramolecular interactions such as hydrogen bonds, metal–ligand interactions, or electrostatic forces is rather challenging with these macromolecules due to the low solubility of the resulting materials. To push the boundary of supramolecular chemistry in optoelectronic materials, the development of supramolecular polymers is particularly interesting since this can allow for the preparation of an entirely new family of optoelectronic materials from a bottom-up approach. , Moreover, the dynamic nature of these interactions gives an opportunity to control the self-assembly, size, and shape of the resulting materials …”

Modulating the Photophysical Properties and Electron Transfer Rates in Diketopyrrolopyrrole-Based Coordination Polymers

Molecular self-assembly through noncovalent interactions is a particularly efficient approach to fine-tune the optoelectronic and photophysical properties of electroactive materials. In metal–ligand coordination polymers, the final properties of the assemblies are directly related to the nature of the metal–ligand interaction. To probe for such influence on the photophysical properties of electroactive materials, a series of coordination polymers based on a well-known organic dye, diketopyrrolopyrrole, was prepared through coordination of a terpyridine-containing monomer with various metal sources, including iron, cobalt, zinc, and manganese. The resulting supramolecular polymers were characterized through multiple techniques, including UV–vis and fluorescence spectroscopy, time-correlated single-photon counting, and femtosecond transient absorption spectroscopy to reveal the impact of the metal source on the final photophysical properties of coordination polymers. As expected, important variations were found between different coordination polymers in terms of absorption, fluorescence kinetics, and electron transfer rate. While iron and cobalt-containing polymers showed ultrafast electrons transfer rates, assemblies from manganese were shown to be much less efficient, confirming the importance of metal centers. This detailed fundamental study unravels some important relationships between metal–ligand interactions, supramolecular self-assembly, and photophysical properties, ultimately leading to new avenues for the design of functional polymers based on organic dyes.
