bis-MPA dendrimers with two different end-groups, acetonide (pyrGn) or alcohol (pyrGn-OH) (n = 1–3), were synthesized, and the pyrenyl group of the dendritic molecules was encapsulated in the arene ruthenium metallacages, [Ru6(p-cymene)6(OO∩OO)3(tpt)2]6+ (OO∩OO = 5,8-dioxydo-1,4-naphtaquinonato (donq) [1]6+ and 6,11-dioxydo-5,12-naphtacenedionato (dotq) [2]6+; tpt =2,4,6-tri(pyridin-4-yl)-1,3,5-triazine)
合成了具有两个不同端基的三代pyr双-MPA树枝状大分子,即丙酮化物(pyr G n)或醇(pyr G n -OH)(n = 1-3),且树枝状分子的pyr基为封装在芳烃钌metallacages,的[Ru 6(p -cymene)6(OO∩OO)3(TPT)2 ] 6+(OO∩OO = 5,8- dioxydo -1,4- naphtaquinonato(动力国际)[ 1 ] 6+和6,11-dioxydo-5,12-naphtacenedionato(dotq)[ 2 ] 6+; tpt = 2,4,6-三(吡啶-4-基)-1,3,5-三嗪)。[guest⊂的主-客体属性1 ] 6+和[guest⊂ 2 ] 6+通过NMR在溶液中研究和UV-VIS光谱法,因此允许亲和常数的确定。此外,评估了这些水溶性宿主-客体系统和the基树枝状大分子对人卵巢癌细胞的细胞毒性。
