Influence of the Chemical Structure of 4-Hydroxybenzylidenealkanones on Nonlinear Optical Properties of Their Complexes with Poly-1,10-Decamethyleneacetamidine

The influence exerted by the length exerted by the conjugation chain in 4-hydroxybenzylidenealkanones on the generation of the third harmonic by complexes of these chromophores with aliphatic polyamidine was studied.     

Synthesis of several series of liquid crystalline polyaroyl-bis-oxyarylates and their structure-property relationships

Several series of liquid crystalline polyaroyl-bis-oxyarylates containing 1,4-phenylene, 4,4'-biphenylene and 2,6-naphthylene units have been synthesized with the use of aroyl-bis-oxyaroyl dichlorides. Melting and clearing temperatures of every polymer under investigation were compared with those of corresponding polyterephthaloyl-bis-4-oxybenzoates.     

Influence of the Chemical Structure of Diarylpenta-1,4-dien-3-one Chromophores on the Nonlinear Optical Properties of Their Polymeric Complexes with Poly-1,10-decamethyleneacetamidine

A study was made of the ability of the ionic complexes formed by diarylalkadienone chromophores with poly-1,10-decamethyleneacetamidine to exhibit third-order nonlinear-optical effects. The chemical structure of the chromophores was correlated with the third harmonic generation efficiency.     

Influence of Metal Complexing on the Nonlinear-Optical Properties of Compounds with High Molecular Symmetry

Coordination bonding of 1,5-diphenylpentadienone was studied with the aim to prepare compounds exhibiting third-order nonlinear optical properties. The volume resistivity of these compounds was studied as influenced by the third-order nonlinear susceptibility tensor.     

Electrolyte Redistribution in Sealed Nickel-Cadmium Batteries with Combined Electrode Design in the Course of Their Prolonged Operation

Studies of the electrolyte redistribution in a sealed nickel-cadmium battery with combined electrode design, fabricated using the separation fabric recommended for replacing the previously used and presently laid off perchlorovinyl fabric, were carried out.     

Synthesis of several series of liquid crystalline polyaroyl-bis-oxyarylates and their structure-property relationships

Abstract

Several series of liquid crystalline polyaroyl-bis-oxyarylates containing 1,4-phenylene, 4,4′-biphenylene and 2,6-naphthylene units have been synthesized with the use of aroyl-bis-oxyaroyl dichlorides. Melting and clearing temperatures of every polymer under investigation were compared with those of corresponding polyterephthaloyl-bis-4-oxybenzoates.
