Undoped single crystals of the organic electro-optic material 4′-nitrobenzylidene-3-
acetamino-4-methoxyaniline were found to show photorefractive effects owing to light …

We measured, for the first time to our knowledge, a net two-beam coupling gain in an
organic crystal. Our photorefractive measurements were carried out in nominally pure …

The electron-injecting material, tris (8-hydroxyquinoline) aluminum (Alq 3)⁠, was introduced
into photorefractive (PR) samples containing the (9-ethyl-9H-carbazol-3-ylmethylent)-(4 …

For the first time photorefractive effects have been observed in 2-cyclooctylamino-5-
nitropyridine (COANP) single crystals doped with 7, 7, 8, 8-tetracyanoquinodimethane …

We present an experimental study of the photorefractive effect in a multifunctional carbazole
trimer sensitized with 2, 4, 7‐trinitro‐9‐fluorenone. The trimer consists of a central carbazole …

Electroreflectance spectra have been measured on organic nonlinear optical crystal MNA (2-
methyl-4-nitroaniline) over the exciton absorption region. From the observed electric-field …

We report the first observation of the photorefractive effect in a polymeric material, the electro-
optic polymer bisphenol-A-diglycidylether 4-nitro-1, 2-phenylenediamine made …

Two-beam-coupling gain coefficients exceeding the absorption coefficient are demonstrated
for the first time to our knowledge in an organic photorefractive system. The material is …

We report the synthesis of a novel charge-transporting polymer based on the charge-
transport unit N, N '-diphenyl-N, N '-bis (3-methylphenyl)-[1, 1 '-biphenyl]-4, 4 '-diamine …

The photorefractive properties of a poled polymer containing the tricyanovinylcarbazole
group with an alkylene spacer are investigated by four-wave mixing experiments and Mach …
