4-(Diethylamino)salicylaldehyde-based twin compounds as NLO-active materials
Abstract 4-(Diethylamino)salicylaldehyde-based twin compounds containing 1,3-indandione and 1,3-bisdicianovinylindane moieties were synthesized and their thermal, optical, photophysical, electrochemical, photoelectrical and nonlinear optical properties were studied. The synthesized compounds form glasses with the glass transition temperatures ranging from 79 to 103 °C. Photoluminescence spectra of the solutions of compounds exhibited red-shifts with the increase of the solvent polarity that was caused by the positive solvatochromic effect. The linear dependencies between the position of the photoluminescence maxima of compounds and the empirical parameter E T (30) of the different solvents …
Derivatives of indandione and differently substituted triphenylamine with charge-transporting and NLO properties
Abstract Derivatives containing electron-donaiting triphenylamino groups and electron-withdrawing indandione moieties were synthesized and their thermal, electrochemical, photoelectrical and nonlinear optical properties were studied. The synthesized compounds form glasses with the glass transition temperatures ranging from 69 to 118 °C. The ionization potentials of the solid samples of the synthesized materials were found to be in the range of 5.48–5.69 eV. Hole-drift mobilities estimated by xerographic time of flight technique in the amorphous layers of 2-({4-[(4-{[(2E)-1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene]methyl}phenyl)(4-methoxyphenyl)amino]phenyl}methylidene)-2,3-dihydro-1H-indene-1…
