Abstract

Herein, we report the synthesis of guest-host systems comprising naphthyl-viologen-naphthyl (Np-Vio-Np) and viologen-naphthyl-viologen (Vio-Np-Vio) guest molecules and their subsequent supramolecular polymerization in the presence of a CB[8] host in water. In addition, the guest complexation of ethyl-terminated trimeric viologen (ETV) with Np-Vio-Np and CB[8] was investigated. As a result of supramolecular interactions, 2D supramolecular organic frameworks with high internal periodicity were constructed. H NMR studies clearly demonstrated the formation of a host-stabilized charge-transfer complex via folding back (Np-Vio-Np and Vio-Np-Vio) in the presence of CB[8]. In the case of ETV + Np-Vio-Np + CB[8], a large polymeric network was formed as indicated by the NMR titrations. UV-vis and fluorescence studies clearly confirm the formation of an inter/intra molecular CT complex upon complexation with cucurbit[8]uril. The size obtained using the dynamic light scattering (DLS) method pinpoints the formation of larger supramolecular aggregates in the order of μm through host-guest assembly, which is further complemented by FESEM and TEM. SAXS measurements indicate the formation of a 2D supramolecular polymer/polymer aggregate with long-range order.

摘要

在此，我们报道了包含萘基紫精-萘基（Np-Vio-Np）和紫精-萘基-紫精（Vio-Np-Vio）客体分子的客体-主体体系的合成及其随后在水中CB[8]主体存在下的超分子聚合。此外，还研究了乙基封端的三聚紫精（ETV）与Np-Vio-Np和CB[8]的客体络合作用。由于超分子相互作用，构建了具有高内部周期性的二维超分子有机框架。1H NMR研究清楚地表明，在CB[8]存在下，通过（Np-Vio-Np和Vio-Np-Vio）回折形成了主体稳定的电荷转移络合物。在ETV + Np-Vio-Np + CB[8]的情况下，如NMR滴定所示，形成了一个大的聚合物网络。紫外-可见光谱和荧光研究清楚地证实了与葫芦[8]脲络合时分子间/分子内CT络合物的形成。使用动态光散射（DLS）方法获得的尺寸表明，通过主客体组装形成了尺寸约为μm的更大的超分子聚集体，场发射扫描电子显微镜（FESEM）和透射电子显微镜（TEM）进一步证实了这一点。小角X射线散射（SAXS）测量表明形成了具有长程有序的二维超分子聚合物/聚合物聚集体。
