style="text-indent:25px">近年來(lái),隨著科學(xué)技術(shù)的發(fā)展,一些新材料的應(yīng)用研究引起了普遍重視。比如有機(jī)電致發(fā)光材料，該類(lèi)材料具有亮度高、光效高以及易于調(diào)節(jié)發(fā)光顏色等優(yōu)點(diǎn)。8-羥基喹啉類(lèi)金屬配合物用作電致發(fā)光材料,是近年來(lái)研究較熱門(mén)的課題?，F(xiàn)就8-羥基喹啉及其衍生物在光度分析和有機(jī)電致發(fā)光器件中應(yīng)用的較新進(jìn)展加以評(píng)述。8-羥基喹啉可與金屬離子形成配位數(shù)為4的配合物MQ2(Q為8-羥基喹啉),如Mg2+、Zn2+、Cu2+等,也可與金屬離子形成配位數(shù)為6的配合物MQ3如Al3+、Fe3+、Ga+等，還可形成配位數(shù)為8的配合物MQ4,如Zr+。Th4等。通過(guò)調(diào)節(jié)溶液的pH值或加入掩蔽劑，可提高反應(yīng)的選擇性。各種金屬離子沉淀的pH值決定了金屬配合物的溶解度,如二價(jià)金屬離子,通常在微堿性或中性介質(zhì)中沉淀，三價(jià)和四價(jià)的金屬離子，由于生成的配合物較穩(wěn)定，甚至在pH值為4時(shí),仍可定量沉淀。</p><p style="text-indent:25px">8-羥基喹啉的毒性屬于微毒，致死量用小白鼠為實(shí)驗(yàn)：鼠經(jīng)口LD50：1200mg/kg；小鼠經(jīng)口LC50：20mg/kg；大鼠腹腔LD：43mg/kg；小鼠皮下LCLo：83600ug/kg；吸入毒性：大鼠：>1210mg/m3/6H。 8-羥基喹啉如果揮發(fā)在環(huán)境之中，會(huì)對(duì)人體做成危害，且8-羥基喹啉揮發(fā)的時(shí)候?qū)χ車(chē)沫h(huán)境物質(zhì)以及生物都具有一定的毒性，不過(guò)8-羥基喹啉不溶于水，但是溶于乙醇，如果水中發(fā)現(xiàn)8-羥基喹啉需要格外的注意。關(guān)于8-羥基喹啉的致ai問(wèn)題，也是有的，在2017年下半年的時(shí)候被國(guó)際衛(wèi)生組織正式確定為三類(lèi)致ai物質(zhì)（對(duì)人的致ai性尚無(wú)法分類(lèi)，即可疑對(duì)人致ai）。喹啉在醫(yī)藥上主要用于制造煙酸系、8-羥基喹啉系和奎寧系三大類(lèi)藥物。</p><div
