“…Most importantly, according to the special characters of Cu 2+ , most of the fluorescent sensors are fluorescent binding, low selectivity and low sensitivity. Fortunately, large amount of chromophores with D-π-A structure was designed and prepared for their application in nonlinear optical materials, and some of the chromophores are suitable for their application as cationic probes [13][14][15][16]. In this paper, we designed a novel chromophore with D-π-A structure, according to the coordination feature of copper(II) cation.…”

Novel chromophore GZP1 with D-π-A structure was designed and prepared for its application as a sensor for the recognition of Cu 2+ ions in polluted water. Reaction of aldimine condensation was used to synthesize chromophore GZP1. Its chemical structure of was characterized by mass spectrum, nuclear magnetic resonance spectroscopy and ultraviolet-visible absorption spectrum. Cu 2+ ions were recognized via fluorescence spectra. Chromophore GZP1 showed specific detection ability of Cu 2+ . 14 other metal ions were used as reference. The detection limit was estimated to be 0.06 μmol/dm 3 in aqueous solution, which was significantly lower than the typical concentration of blood Cu 2+ in normal individuals and the limit of copper(II) in drinking water.

“…Furthermore, the even order tensor β, responsible for second-order NLO effects (for example SHG), requests non-centrosymmetric molecular structure and crystal packing. It is also well established that the macroscopic polarization of a bulk material under an applied strong electric field can be regarded as an averaged sum of the individual molecular polarizations [24]:…”

Abstract:In recent years, there has been extensive research and continuous development on second-order nonlinear optical (NLO) crystal materials due to their potential applications in telecommunications, THz imaging and spectroscopy, optical information processing, and optical data storage. Recent progress in second-order NLO ionic organic crystal materials is reviewed in this article. Research has shown that the second-order nonlinear optical properties of organic crystal materials are closely related to their molecular structures. The basic structures of ionic organic conjugated molecules with excellent nonlinear optical properties are summarized. The effects of molecular structure, for example, conjugated π electron systems, electronic properties of donor-acceptor groups, and different counter-anion effects on second order NLO properties and crystal packing are studied.

“…Comparing with the traditional inorganic crystals and semiconductor nonlinear optical (NLO) materials, organic electro-optic (EO) polymers exhibit substantial advantages in the following aspects: fast response time, easy processing, low dielectric constant and ultra-large EO coefficients [1][2][3][4][5]. So, researchers have paid more and more attentions to organic EO materials in the past decades.…”
