| Abstract: | Two kinds of novel molecular glasses based on self-assembly dendritic chromophores are designed and synthesized as second-order nonlinear optical (NLO) materials, which named ETO and ETF. The chromophore glasses ETO and ETF showed excellent film-forming ability by themselves. Their glass transition temperatures (Tg) were determined at 41 ℃ and 39 ℃, respectively. The in-situ second harmonic generation (SHG) measurement revealed the resonant second-order NLO coefficient (d33) values of 38 and 32 pm/V for the poled films of ETO and ETF, respectively. The results indicate molecular glasses provide a new possible way different from the conventional polymer approach to prepare second-order NLO materials. |
