Exciton structure and dynamics in π-conjugated molecular wires Naresh Duvva, Habtom B. Gobeze, Isaí Barboza-Ramos, Kirk S. Schanze Chemical Science, 2025 Exciton and charge transport through π-conjugated oligomers and polymers is critical to the performance of organic electronic materials and essential for understanding carrier transport mechanisms on the nanoscale.
Synthesis and photophysics of platinum capped phenylene ethynylene oligomers Kirk Schanze, Julia M. Keller, Abigail H. Shelton, Randi S. Price, Naresh Duvva Arkivoc, 2024 A series of dinuclear platinum-acetylide oligomers Ph n Pt 2 were synthesized, consisting of alkylated phenylene ethynylene oligomers of varying lengths (n = 1, 2, 4 and 9) capped by trans-bis(tributylphosphine)(2-phenylethynyl)-platinum(II) end groups. The oligomers were designed to examine the effects on the excited state properties between two platinum moieties of increasing organic spacer distances. Optical data conclude that the ground state and singlet exciton remain delocalized throughout the series, but approaching its limit
Intramolecular Photoinduced Energy and Electron Transfer Reactions in Phenanthroimidazole-Boron Dipyromethane Donor-Acceptor Dyads Swathi Nenavath, Naresh Duvva, Ram R. Kaswan, Gary N. Lim, Francis D’Souza, et al. Journal of Physical Chemistry A, 2023 Donor-acceptor systems in which a donor phenanthroimidazole (PhI) is directly connected to a BODIPY acceptor (Dyad1) and separated by an ethynyl bridge between PhI and BODIPY (Dyad2) have been designed, synthesized, and characterized by various spectroscopic and electrochemical techniques. Optical absorption and 1H NMR characteristics of both dyads with those of constituent individuals suggest that there exists a minimum π-π interaction between phenanthroimidazole and BODIPY. Quenched emission of both the dyads was observed when excited either at phenthaoimidazole absorption maxima or at BODIPY absorption maxima in all three investigated solvents. The detailed spectral analysis provided evidence for an intramolecular photoinduced excitation energy transfer (PEnT) from the singlet excited state of phenanthroimidazole to BODIPY and photoinduced electron transfer (PET) from the ground state of phenanthroimidazole to BODIPY. Transient absorption studies suggest that charge-separated species (PhI•+ - BODIPY•-) are generated at a rate constant of (1.16 ± 0.01) × 108 s-1 for the dyads Dyad1 and (5.15 ± 0.03) × 108 s-1 and for Dyad2 whereas energy transfer rate constants were much higher and were on the order of (1.1 ± 0.02) × 1010 s-1 and (1.6 ± 0.02) × 1010 s-1 for Dyad1 and Dyad2, respectively, signifying their usefulness in light energy harvesting applications.
