【摘要】：以二苯-4,4′-二羧酸和六水硝酸鋅為原料,在相同反應(yīng)條件下,通過改變不同的輔助配體(2,2′-二甲基-4,4′-聯(lián)吡啶和三乙烯二胺),合成出2個金屬有機配位聚合物:{[Zn(DBA)(dmbpy)_(0.5)]·2H_2O}_n(1)和[Zn_2(DBA)_2(dabco)]_n(2)(H_2DBA=二苯-4,4′-二羧酸,dmbpy=2,2′-二甲基-4,4′-聯(lián)吡啶,dabco=三乙烯二胺)。通過元素分析、紅外光譜、差熱分析、X射線粉末衍射和X射線單晶衍射等手段對配合物進行了結(jié)構(gòu)表征。結(jié)果顯示,化合物1為二維(4,4)網(wǎng)絡(luò)結(jié)構(gòu),2個二維結(jié)構(gòu)在平行方向上通過互鎖進一步形成2D→2D的互鎖網(wǎng)絡(luò)結(jié)構(gòu)�；衔�2為一維帶狀結(jié)構(gòu)。熱穩(wěn)定性表明化合物1能夠穩(wěn)定到370℃;而化合物2穩(wěn)定性差。熒光分析表明常溫固態(tài)下配合物1和2均發(fā)射藍色熒光,熒光壽命分別為231.4 ns和2.33 ns。
[Abstract]:Under the same reaction conditions, dibenzene-4na-dicarboxylic acid and zinc nitrate hexahydrate were used as raw materials. Two metal-organic coordination polymers, {[Zn (DBA) (dmbpy) _ (0.5)] 2H _ 2O} n (1) and [Zn _ 2 (DBA) _ 2 (dabco)] n (2) (H2DBA = Dmbpyridine), have been synthesized by changing different auxiliary ligands (2H _ 2H _ 2-dimethyl -4N ~ (4) -bipyridyl) and triethylenediamine. (H2DBA = diphenylpyridine (DBA) _ (0.50) -2H _ 2O} n (1) and [Zn2 (DBA) _ 2 (dabco)] n (2). The structures of the complexes were characterized by elemental analysis, infrared spectroscopy, differential thermal analysis, X-ray powder diffraction and X-ray single crystal diffraction. The results show that compound 1 is a two-dimensional (4 ~ 4) network structure, and two two-dimensional structures are interlocked in parallel directions to form a 2D / 2D interlocking network structure. Compound 2 is a one dimensional band structure. Thermal stability indicated that compound 1 was stable to 370 鈩，
