FTC-containing molecules: large second-order nonlinear optical performance and excellent thermal stability, and the key development of the "Isolation Chromophore" concept. Issue 48 (25th November 2016) - Chen, Pengyu
Abstract : The extended application of the concept of "Isolation Chromophore" produced a d 33 value of 384 pm V −1 @ 1950 nm. Abstract : A series of second-order nonlinear optical (NLO) molecules, M1–M5, were designed and successfully synthesized through the convenient ''click chemistry'' reaction, which contain two different types of chromophore moieties, the FTC chromophore and nitro-based azo ones, according to the concept of "Isolation Chromophore". All these five molecules possess excellent thermal stability and very large NLO performance, with an ultrahigh d 33 value of 384 pm V −1 at the wavelength of 1950 nm achieved forM1, furthering the rational design of excellent NLO materials.
