A Complete Experimental Assessment of Franck-Condon Structural Effects for an Irreversible Outer-Sphere Electron-Transfer Reaction: Applications of Time-Dependent Raman Scattering Theory to the One-Electron Reduction of 4-Cyano-N-methylpyridinium

A complete experimental description of the vibrational Franck-Condon barrier to the one-electron reduction of 4-cyano-N-methylpyridinium cation (NC-py-Ch3+) has been obtained.Because of the chemical irreversibility of the electron transfer, the reaction is not readily amenable to study by conventional structural methods.The approach successfully employed here, however, was a time-dependent analysis of near-resonant Raman scattering where resonance was achieved by pairing the cation to iodide anion; the pairing gives rise to a weak (ε = 565 M-1cm-1) outer-sphere charge-transfer band centered at 428 nm in acetonitrile as solvent.The time-dependent analysis of scattering yields vibrational frequencies, coordinate displacements, and single-mode barrier contributions for each of 13 modes involved in outer-sphere electron transfer.Depolarization measurements, excitation profiles, and scattering studies with the nonchromophoric +, Cl-> ion pair confirm that the vibrational structural data pertain directly to the outer-sphere charge-transfer reaction rather than to higher lying electronic transitions.

Perovskite solar cell additive based on cyanopyridine ionic liquid and applications thereof

The invention relates to a perovskite solar cell additive based on a cyanopyridine ionic liquid and applications thereof. The chemical structural formula of the additive is represented in the description, in the formula, n represents an integer from 0 to 9; and Z represents Br, I, Cl, BF4, PF6, or TFSI. A special chemical structure is designed so that a cyano group is connected to a pyridine ring;due to the strong polarity of the cyano group, the morphology of a perovskite film can be controlled during the growth process, the prepared grains have a greater size; at the same time, due to the synergistic effect between the cyano group and pyridine cations, the internal defects in the perovskite film are reduced; and the prepared perovskite film has a very good fluorescent property.

Efficient macrocyclization achieved via conformational control using intermolecular noncovalent π-cation/arene interactions

Quinolinium salt 3 is an effective additive that acts as a conformation control element (CCE) to promote macrocyclization to form rigid cyclophanes via olefin metathesis or Glaser-Hay coupling, which do not cyclize in the absence of the additive. The additives are easily synthesized and highly modifiable and have solubility profiles which allow for simple recovery via filtration.
