Design and synthesis of novel H-Shaped chromophore for enhanced nonlinear optical properties

Synthesis and characterization of Y-shaped optical nonlinear chromophores with strong acceptors

“…Dipole–dipole interaction between molecules will hinder the poling orientation of chromophores under the action of the electric field. 47 The introduction of steric tert -butyl(methyl)diphenylsilane groups could Increase the distance between molecules to reduce the electrostatic interaction between molecules and improve the polarization efficiency. 48…”

“…Dipole-dipole interaction between molecules will hinder the poling orientation of chromophores under the action of the electric field. 47 The introduction of steric tert-butyl(methyl)diphenylsilane groups could Increase the distance between molecules to reduce the electrostatic interaction between molecules and improve the polarization efficiency. 48 For the chromophores L1-L3 with CF 3 -TCF acceptor, the average poling efficiencies (r 33 /E p ) of the three chromophores were determined by linear fitting of the electro-optic activity versus electric poling field as shown in Fig.…”

Isolation strategy for a novel luminescent Eu3+-pyridine-2,6-dicarboxylic acid complex with high compatibility and stability for light-conversion agricultural films

“…Significantly, the isolation group strategy has been successfully used to minimize the strong intermolecular electrostatic dipole-dipole interactions among chromophores in the field of nonlinear optical materials. [27][28][29] In this strategy, bulky groups are introduced to the skeleton of the chromophore, or two chromophores are connected by a flexible alkyl chain to increase their steric hindrance. The research results so far have indicated that the orientation of incorporated chromophores can be well aligned with a minimum molecular migration during the device fabrication.…”

Recent Progress in Design of Organic Electro‐optic Materials with Ultrahigh Electro‐optic Activities†

“…As the source of the Pockels effect in inorganic‐organic hybrid modulators, OEO materials presented high r 33 values which come from the ordered nonlinear optical (NLO) chromophores. [ 4,8,45‐58 ] Current OEO materials designed by theory‐guided method have demonstrated r 33 values higher than 1000 pm/V exceeding that of the commercial lithium niobate over an order of magnitude. [ 47,57‐60 ] Greatly improved EO activity affords tiny device size and ultra‐low halfwave voltage for photonic devices that contribute significantly to the chip‐scale integration on silicon photonic platform.…”
