Abstract The application of dithieno [3, 2-b: 2′, 3′-d] pyrroles (DTPs) in conjugated
organic polymers has resulted in a variety of materials with reduced and low band gaps that …

Dithienothiophenes (DTT) possess three fused thiophene rings, the orientations of which
vary depending on the locations of the sulfur atoms of the peripheral thiophenes. Six …

The fluorescence spectra of poly (p-phenylenevinylene) have been investigated at 6 K
employing site-selective laser spectroscopy. They delineate the existence of a well-defined …

Electric-field-modulated reflectivity of three different polydiacetylenes—PTS, poly [2, 4-
hexadiyne-1, 6-diol-bis (p-toluene sulfonate)]; PFBS, poly [2, 4-hexadiyne-1, 6-diol-bis (p …

Measurements of the third-order optical nonlinear susceptibility χ^(3) have shown that
nonlinearity around the single-photon absorption region is dominated by the saturation …

Generation and transport of charge carriers in poly (2-phenyl-1, 4-phenylenevinylene) has
been investigated by means of dc and transient photoconductivity. Photocarrier production is …

Oxidative polymerization studies of N-functionalized dithieno [3, 2-b: 2 ', 3 '-d] pyrroles
(where substituent= hexyl, octyl, decyl, octadecyl, tert-butyl, 2-ethylhexyl, or p-hexylphenyl) …

Introduction There has been a great deal of interest in polymeric organic compounds
showing unusual electronic and optical properties. la, b When this interest seemed to be …

The crystal structure of polythiophene is analyzed by the Rietveld whole‐fitting method on
the X‐ray diffraction powder profile. Experimental data allow only a bidimensional …

Gas-phase ionization and attachment energy values of the first few oligomers of furan have
been determined experimentally and by semiempirical calculationsand extrapolated to …
