Lee, Yeong-Beom; Young Woo, Han; Yoon, Chong-Bok; Shim, Hong-Ku published the artcile< Simple synthetic route to soluble polyimides via nitro-displacement reaction and their second-order nonlinear optical properties>, Application of C19H34O2, the main research area is polyimide preparation second order NLO property.
Nonlinear optical (NLO) functionalized polyimides were directly synthesized using the nitro-displacement reaction between an alkanediol monomer and a diimide monomer without a thermal curing step. The polyimides were soluble in aprotic polar solvents such as DMSO, dimethylacetamide, DMF, and N-methylpyrrolidone, and showed glass transitions at temperatures between 172 and 198°C. We observed good thermal stability up to around 300°C (at 5% weight loss) for the polymers. The weight-average mol. weights of the resulting polymers were 10,400-15,100 (Mw/Mn = 1.84-2.00). The poled polymer films showed good nonlinearity (d33 = 76 pm V-1) in the Maker fringe method for second harmonic generation.
