Construction of a simple crosslinking system and its influence on the poling efficiency and oriental stability of organic electro-optic materials

Abstract

A new fluorinated polycarbonate was synthesized by solution polymerization of bisphenol AF, anthracen-9-ylmethyl-4,4-bis(4-hydroxyphenyl)pentanoate with triphosgene.

Preparation of Polyphenylene Ring Derivative Dyes with Wide Wave Absorption Properties and Their Performance Study

“…As TCNE is continuously added to the solution, the absorption peak at 470 nm gradually increased until the absorption peak at 376 nm decreased to a minimum after the addition of 2 equivalents of TCNE, which indicates the complete conversion of Q to Q-11. In previous works [ 21 , 22 , 23 , 24 , 25 , 26 ], click chemistry is shown to be efficient and free of side reactions. In Figure 2 a, the production of extinction dots at 348 nm and 405 nm proves that the click reaction is side-reaction free.…”

Click reactions to prepare symmetrical and asymmetrical and broad-band near-infrared absorbing dyes

“…22 These chromophores exhibit intense, low-energy, intramolecular charge transfer and high third-order optical nonlinearities. [23][24][25][26] Using this rapid and efficient synthesis method and click chemical reagents, many materials with good third-order nonlinear optical properties have been prepared, such as porphyrin, fullerene and thiophene derivatives. Nevertheless, materials prepared via the [2+2] click reaction can only absorb a portion of the visible band, and such materials that absorb over a wide band have never been reported.…”
