A modifiable double donor based on bis(N-ethyl-N-hydroxyethyl)aniline for organic optical nonlinear chromophores

Abstract

A strong modifiable double donor based on Bis(N-Ethyl-N-hydroxyethyl)aniline -derivatived structure was developed and applied to nonlinear optical materials for the first time. Three isolation groups were introduced into the donor...

An intramolecular-locked strategy for designing nonlinear optical materials with remarkable first hyperpolarizability

“…Different strategies 4,[6][7][8][9][10][11] have been successively proposed to enhance the first hyperpolarizability. Among those strategies, the strategy of designing D-A and Dp-A organic molecules has become a quite important strategy in enhancing the first hyperpolarizability, 4,[11][12][13][14][15][16] mainly owing to the D-A and D-p-A organic molecules holding strong inter(intra)molecular charge transfer (ICT) and having highly delocalized p-electron characteristics. The organic molecules, on the other hand, have also a lower laser damage threshold and easy modification characteristics.…”

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

“…reported a series of chromophores using bis( N , N ‐diethylaniline) structure as the donor with improved β value and EO activity (Figure 4). [ 76,84‐89 ] Bis( N , N ‐diethylaniline) structure has very strong electron‐donating property due to the double donor structure in which one N , N ‐diethylaniline acts as the main donor, and the other one as the auxiliary donor. Apart from the enhanced electron‐donating ability, bis( N , N ‐diethylaniline) donor also has strong site‐isolation property that comes from the twisted configuration of auxiliary donor.…”

“…Some chromophores can be poled in neat without any EO‐inactive matrix. [ 47,75‐76 ] The performance of electric field poled OEO materials has been improved to 300—600 pm/V level. After reported record‐high r 33 value (556 ± 90 pm/V) by Jin et al .…”

Systematic Study on Nonlinear Optical Chromophores with Improved Electro-Optic Activity by Introducing 3,5-Bis(trifluoromethyl)benzene Derivative Isolation Groups into the Bridge

“…In order to meet the application requirements of these technologies, organic electro-optic materials need to have a large EO coefficient ( ), robust thermal stability, and good chemical stability. Through rational chromophore design and supra-molecular engineering such as molecular self-assembly and binary chromophore containing dendrimer glasses and polymers, the properties of organic electro-optic polymer materials have been greatly improved [ 21 , 22 , 23 , 24 , 25 ].…”
