On March 20, 2020, Mi, Yan; Yao, Jiabin; Ma, Jingyu; Dai, Ling; Xiao, Chao; Wu, Wanhua; Yang, Cheng published an article.Electric Literature of 150-78-7 The title of the article was Fulleropillar[4]arene: The Synthesis and Complexation Properties. And the article contained the following:
A pillar[4]arene monoquinone (prepared by oxidation of permethylpillar[5]arene) underwent ring opening mediated by Cs2CO3 in DMF to yield the multihydroquinone ether dialdehyde I in 5% yield. The regioselective Prato reaction of I with fullerene C60-Ih and sarcosine yielded a trans-4 macrocyclic bisadduct as the major product in 12% yield. The fulleropillararene macrocycle formed a 1:1 complex with 4,4′-bis(dodecyl)-1,1′-bipyridinium dibromide with a binding constant of > 6500 M-1, a significantly stronger affinity than the binding of the viologen to either permethyl pillar[5]arene or the parent pillararene monoquinone. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Electric Literature of 150-78-7
