“…It was previously shown that the rate of the second-harmonic intensity decreases after turning off the applied electric field depends on chemical structure of a polymer, the nature of non-specific and specific interactions between fragments of chains and free volume of the polymer network. 14…”

“…27,28 Thermal analysis Thermal analysis of the polymer films based on glycidyl derivatives of quercetin was carried out in our previous work. 14 It was showed that the increase in number of glycidyl substituents in the quercetin moiety results in the decrease of T g , which could be explained by formation of the polymer networks with greater free volume. The growth of the free volume can be due to formation of a greater number of disordered regions in the polymer network of higher mobility of the polymer chains.…”

“…In our previous publications, 14,15 new NLO active organic polymers containing chromophore fragments based on widespread natural compounds as 3,5,7,3 ′ ,4 ′ - penthahydroxyflavone (quercetin) and its derivatives were obtained. These chromophores were not used as dopants but were inserted in the main polymer chains that would significantly increase the relaxation time of chromophores.…”

Cross-linked polymers with chromophore fragments built-in main chains can, depending on their structure and synthesis conditions, keep during a long time the orientation of chromophores that is necessary to create new organic polymer materials demonstrating nonlinear optical properties. The present work is devoted to cross-linked polymers on the basis of di-, tri-, and tetraglycidyl ethers of quercetin-8-sulfonic acid sodium salt (3,5,7,3′,4′-penthahydroxyflavon-8-sulfonic acid sodium salt) which were synthesized, and then, poled in electrical field of corona discharge. Study of thermal, optical, and nonlinear optical parameters of the polymer films was carried out. It was found that the polymers obtained from di- and triglycidyl ethers of quercetin-8-sulfonic acid sodium salt are characterized by the higher values of macroscopic quadratic susceptibilities comparing with such a value for polymer obtained from tetraglycidyl ether of quercetin-8-sulfonic acid sodium salt. However, the latter polymer demonstrates a minimal intensity of relaxation processes that evidence its highest long-term stability, and thus, could be used as a nonlinear optical material. It is supposed that the difference of the nonlinear optical properties is due to peculiarities of intermolecular interactions in physical network of the polymers, namely, to the difference between numbers of hydrogen bonds formed by hydroxyl groups of chromophore fragments and number of hydrogen bonds linked of inter fragmental parts of the polymeric chains.

“…The main problem with the use of inorganic crystals is associated with the difficulty of growing samples of large sizes and shapes. NLO polymer materials compared to inorganic crystals, without aforementioned shortcomings, have a faster NLO response, and they have higher technological and economical indices [1][2][3]. It should be noted that the NLO response of the chromophores doped polymer NLO materials directly depends on the NLO response of the chromophore compound, which is a dopant in the polymer matrix.…”

In this work polymer nonlinear optical (NLO) materials in the form of thin films based on 3,7,3 ' ,4 'tetrahydroxyflavone and diglycidyl ether of bisphenol A were obtained and investigated. It was found that the influence of the chromophore concentration on values of the macroscopic NLO susceptibilities (χ (2) of doped polymer films has extreme character. The maximum value of χ (2) is 6.11 pm/V at the concentration of dopant 20 wt %.
