Proquinoid acceptors as building blocks for the design of efficient π- conjugated fluorophores with high electron affinity

The association of aromatic electron donor groups with proquinoid acceptors leads to π-conjugated fluorophores combining tunable emission wavelength at constant geometry, high fluorescence efficiency and high electron affinity.

Optical activity of heteroaromatic conjugated polymer films prepared by asymmetric electrochemical polymerization in cholesteric liquid crystals: Structural function for chiral induction

We electrochemically polymerized various achiral heteroaromatic monomers in left-handed helical cholesteric liquid crystal (CLC) media. Circular dichroism (CD) spectroscopy revealed that most of the resulting conjugated polymer films exhibited both the first negative and second positive Cotton effects near their absorption maxima. This indicates left-handed helical aggregation of the conjugated main chains, which is consistent with left-handed helical order of the CLC. This result suggests that the left-handed helical CLC environment induced left-handed helical aggregation of the polymers during the electrodeposition. However, CD intensity of the polymers depends on the structure of the parent monomers. Systematic investigation of the relationship between monomer structures and optical activity of the polymers indicates that linearity of the conjugated main chains and excluded volume interaction between the monomers and the CLC are important factors for producing optical activity of the polymers.

Synthesis and physical properties of benzopyridazine-based conjugated molecules

A series of novel organic conjugated molecules (5a-5d) comprising 2,3-benzopyridiazine as electron-withdrawing core and thiophene derivatives as electron-donating arms have been synthesized successfully in good yields. The ultraviolet-visible (UV-Vis) absorption spectra and fluorescence spectra of 5a-5d revealed that the optical properties are strongly influenced by the interactions between nitrogen and sulfur atoms in the conjugated backbone, as well as the position of the alkyl chains in the thiophene rings. The experimental results and theoretical calculation data clearly indicated that the band gap and the energy levels of LUMO and HOMO could be fine-tuned by the position of alkyl chains in the thiophene rings. Thus, the structure-property correlation of this class of conjugated molecules can be well established. A series of organic conjugated molecules containing 2,3-benzopyridiazine as electron-withdrawing core and thiophene derivatives as electron-donating arms have been synthesized successfully. The optical properties and electrochemical behaviors of these molecules can be fine-tuned through changing the position of alkyl chains in the thiophene rings. Copyright

Design of reversible multi-electron redox systems using benzochalcogenophenes containing aryl and/or ferrocenyl fragments

2,3-Disubstituted benzo[b]thiophenes, 1,3-disubstituted benzo[c]thiophenes, and 1,3-disubstituted benzo[c]selenophene have been systematically and selectively synthesized from benzo[b]thiophene or phthaloyl dichloride as a starting material, respectively. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The cyclic voltammograms of the chalcogenophene derivatives containing aryl fragments showed well-defined reversible both anodic and cathodic steps derived from the unusually stable 5π chalcogenophene radical cations and 7π chalcogenophene radical anions. The cyclic voltammograms of the novel chalcogenophene derivatives containing ferrocenyl fragments showed a well-defined reversible cathodic step derived from the unusually stable 7π chalcogenophene radical anions and two distinct reversible anodic steps derived from ferrocenium cations separated from each other by a thiophene-heterocycle. The radical character of several novel 7π chalcogenophene radical anions was measured by ESR spectroscopy.
