style="text-indent:25px">近年來,金屬有機(jī)配合物已經(jīng)成為一個熱點(diǎn)研究領(lǐng)域,在能源氣體儲存、有毒氣體吸附分離、發(fā)光材料、異相催化等領(lǐng)域具有重要的應(yīng)用價值。本文簡單介紹了配位化合物發(fā)展歷程,主要介紹了超分子配位化合物和有機(jī)金屬配合物的發(fā)現(xiàn)、合成方法以及在各個領(lǐng)域的應(yīng)用,引出研究目的和研究內(nèi)容。本文利用六種不同的有機(jī)配體合成了三類結(jié)構(gòu)不同的配位化合物,并通過X-射線單晶衍射、紅外光譜、紫外光譜、粉末X-射線衍射、熱重分析、熒光光譜對這三類配位化合物結(jié)構(gòu)和性質(zhì)進(jìn)行表征。利用兩種8-羥基喹啉衍生物作為配體與Cr3+在溶劑熱的條件下分別構(gòu)筑了兩種超分子配位化合物,研究了這兩種配位化合物的熒光性質(zhì)。隨后利用有機(jī)羧酸配體合成了三種具有相似的晶體結(jié)構(gòu)有機(jī)金屬配合物,其中含有脲基的二維銅基金屬有機(jī)配合物具有優(yōu)異催化活性,特別是催化Friedel-Crafts烷基化反應(yīng)和Knoevenagel縮合反應(yīng),其催化Friedel-Crafts烷基化反應(yīng)的產(chǎn)率可以達(dá)到99%,并且可以循環(huán)多次使用。</p><p style="text-indent:25px">8-羥基喹啉漏光會變成黑色，有石炭酸氣味。可以溶于強(qiáng)酸、強(qiáng)堿。在酸中的作用能結(jié)合氫離子，在堿中的作用能電離成負(fù)離子。8-羥基喹啉可以普遍的用于金屬的分離工作，作為制染料和yao物的中間體，制作殺菌機(jī)等用途。8-羥基喹啉的表征：在乙酸一鹽酸水溶液中，以鄰氨基苯酚、鄰硝基苯酚和丙烯醛為原料，合成了8-羥基喹啉，得到的優(yōu)化反應(yīng)條件為：(鄰氨基苯酚)：(鄰硝基苯酚)：(丙烯醛)：(乙酸)=1：0.5：1.8：2.0，在90~100℃下反應(yīng)5?h，經(jīng)中和、蒸餾得到8-羥基喹啉，收率136?(以鄰氨基苯酚計(jì))。該法簡便、快速且成本較低，易于工業(yè)化。8-羥基喹啉可作為防霉劑、工業(yè)防腐劑以及聚酯樹脂、酚醛樹脂和雙氧水的穩(wěn)定劑。</p><div
