【摘要】：金屬離子是分子組成物質(zhì)中的金屬元素,它與環(huán)境科學(xué)及生命科學(xué)等眾多學(xué)科存在密切聯(lián)系,于是文中提出設(shè)計(jì)一種大環(huán)多胺金屬配合物,利用熒光傳感超分子體系對(duì)金屬離子客體進(jìn)行識(shí)別與檢測(cè)。首先,由于大環(huán)多胺配體的成環(huán)氮原子具備強(qiáng)配位能力,利用Richman-Atkins環(huán)化合成法初步合成基礎(chǔ)中間化合物,通過(guò)控制反應(yīng)物的摩爾量獲得收率高的關(guān)鍵中間體,并與二價(jià)銅離子Cu(Ⅱ)通過(guò)合適的反應(yīng)溫度及反應(yīng)溶劑形成多功能大環(huán)多胺金屬配合物;其次,依據(jù)待分析配合物反應(yīng)部位的特殊性質(zhì),利用熒光傳感體系對(duì)金屬離子客體實(shí)現(xiàn)識(shí)別及檢測(cè)過(guò)程,將熒光團(tuán)作為發(fā)射熒光的功能基團(tuán),離子受體當(dāng)作金屬離子識(shí)別與檢測(cè)的接受團(tuán),通過(guò)光誘導(dǎo)電子轉(zhuǎn)移PET體系完成對(duì)超分子的識(shí)別過(guò)程。
[Abstract]:Metal ions are metal elements in molecular components, which are closely related to many subjects, such as environmental science and life sciences, so it is proposed to design a macrocyclic polyamine metal complex.The metal ion guest was identified and detected by fluorescence sensing supramolecular system.First of all, because of the strong coordination ability of macrocyclic polyamine ligands, the base intermediate was synthesized by Richman-Atkins cyclization, and the key intermediates with high yield were obtained by controlling the molar amount of reactants.The metal complexes of multifunctional macrocyclic polyamines were formed with Cu (鈪，
