| Because complex 1 belongs to crystal class 222 and point group (D2), and complex 2 crystallizes in the space group Cc, which belongs to polar point group Cs, becauseof the ligand coordination enhancing the rigidity of ligand, a good donor acceptor system is formed, which is essential for SHG effect, so we performed quasi-Kurtz [25]. SHG measurements on powder sample of 1 and 2 to confirm its acentricity as well as to evaluate its potential application as second-order NLO material. The compound 1 displays a second harmonic generation (SHG) response comparable to urea and 2 display SHG activity with a response of approximately 0.8 times of that for urea. |

| 由于配合物1屬于222晶族和D2點(diǎn)群,而配合物2結(jié)晶于Cc空間群,屬于極性CS點(diǎn)群,同時(shí)配體的配位增加了配體的剛性而形成了良好的供體受體系統(tǒng),這對SHG效應(yīng)是必不可少的,因此我們進(jìn)行準(zhǔn)Kurtz實(shí)驗(yàn)。 對粉末樣品1和2進(jìn)行SHG測試證實(shí)了其非心特性以及可作為潛在的二階非線性光學(xué)材料;衔1表現(xiàn)出與尿素相當(dāng)?shù)亩沃C波生成(SHG)響應(yīng),而2的SHG活性響應(yīng)約為尿素的0.8倍。 |
