Stacking of hydrazone-bridged linear tetrathiafulvalene radical cations
摘要:
Four compounds M1, M2, M3, M4, and one polymer P1 containing tetrathiafulvalene (TTF) units have been synthesized by the condensation of TTF-derived aldehyde and acylhydrazine precursors. UV-vis absorption and electron paramagnetic resonance spectroscopy as well as scanning electron microscopy reveal that the TTF+ stacking of the polymer is considerably enhanced compared to that of the shorter compounds in polar solvents.

Provided is a layered structure having a first electrode, a second electrode, a light emitting layer or a charge separation layer located between the first electrode and the second electrode, and a layer located between the light emitting layer or the charge separation layer and the first electrode and containing a polymer having a repeating unit containing one or more ionic groups selected from two specific groups and one or more specific polar groups. Also provided is a polymer having, as the repeating unit containing one or more ionic groups selected from two specific groups and one or more specific polar groups, one or more repeating units selected from four specific repeating units containing an aromatic group. The layered structure of the present invention provides an electroluminescent device capable of emitting light at a high luminance and a photoelectric conversion device having a high photoelectric conversion efficiency.

A number of potential HIV protease inhibitory peptides that contain the dihydroxyethylene isostere were prepared and evaluated for their enzyme binding affinity and antiviral activity in cell cultures. From the template of a previously reported active peptide A, modifications at the N- and C-terminal groups were assessed for potential maintenance of good inhibitory activity of the resulting peptides
