Various novel types of supramolecular nanostructures formed by nonamphiphilic azobenzene derivatives, G1 or G2 have been successfully fabricated, where G2 is structurally similar with G1 but an extra phenoxy group is connected with the azobenzene motif . Micellar structures can be obtained from the self‐assembly of G1, which further transform to large‐sized spindle structures; while nanorods can be
由非两亲性偶氮苯衍生物G1或G2形成的各种新型超分子纳米结构已被成功制备,其中G2与G1在结构上相似,但额外的苯氧基与偶氮苯基序相连。胶束结构可以通过G1的自组装获得,然后进一步转化为大型主轴结构。纳米棒最初可以由G2形成,G2会逐渐聚集形成更大尺寸的分层结构。此外,发现添加WP6后可与G1或G2形成包合物。分开,所述nonamphiphilic G1和G2从而超分子两亲物相反的WP6 ⊃ G1和WP6 ⊃ G2,分别。因此,以上WP6 → G1和WP6 → G2复合物都可以进一步组装形成超分子二元囊泡,这些超小分子二元囊泡将逐渐转变为纳米管(WP6 → G1)或排列良好的纳米片(WP6 → G2)。
