Novel ethyl thiourea compounds 1a – 1f have been synthesized in good to high yields. The structure of all compounds was identified using FT-IR, 1H NMR, 13C NMR, and ESI-Mass. The compound 1-ethyl-3-(3-methoxyphenyl) thiourea 1d was obtained in crystalline form by recrystallization from DMSO. However, single crystal X-ray analysis revealed that the 1d molecule crystallized in a monoclinic crystal system with space group of P21/n and the unit cell dimensions are a = 11.0797(7) Å, b = 8.6081(6) Å, c = 11.9698(7) Å, α = 90°, β =104.543(2)°, γ = 90°, Z = 4 and V = 1105.04(12) Å3. The preliminary optical sensor properties for metal ions of 1a – 1f were investigated using naked-eye. The results determined that all compounds have the ability as naked eye sensors for mercury (Hg) and argentum (Ag) metal ions.
新颖的乙基硫脲化合物 1a - 1f 以良好至高产率合成。利用傅立叶变换红外光谱、1H NMR、13C NMR 和 ESI-质谱鉴定了所有化合物的结构。化合物 1-乙基-3-(3-甲氧基苯基)硫脲 1d 是通过从 DMSO 中重结晶得到的晶体。然而,单晶 X 射线分析表明,1d 分子在单斜晶系中结晶,空间群为 P21/n,单胞尺寸为 a = 11.0797(7)埃,b = 8.6081(6)埃,c = 11.9698(7)埃,α = 90°,β = 104.543(2)°,γ = 90°,Z = 4,V = 1105.04(12)埃3。用肉眼初步研究了 1a - 1f 金属离子的光学传感器特性。结果表明,所有化合物都具有作为汞(Hg)和银(Ag)金属离子裸眼传感器的能力。
