1.Construction of Supramolecular PolymersWhen a guest part was covalently attached to cyclodextrin (CD), they formed supramolecular dimers, a cyclic daisy chain, supramolecular oligomers, and polymers. t-Boc-cinnamamide-α-CD was found to form chiral supramolecular polymers in aqueous solutions. Supramolecular poly[2]rotaxane polymers and supramolecular α-, β-CD copolymers were obtained.2.Dymanics of Supramolecular PolymersWe investigated a new one-pot method to prepare polyrotaxanes containing γ-CDs by the photocyclodimerization reactions of 9-anthryl groups at the ends of the polymer chain in the presence of γ-CDs.We have constructed pseudo-rotaxanes of α-CD with axle molecules bearing pyridyl end caps via kinetic control of threading of α-CD onto axle molecules. A single substituted pyridyl group attached to the ends of the axle molecule regulated the rate for α-CD passing them. Two methyl substituents could govern the degree of complex formation of a-CD with guest molecules and resu … More lted in the distinction of face direction of CD molecules entering the axle ends. α-CDs were arranged in one direction at two station units of the axle molecule.Poly(ethylene glycol) (PEG)-substituted CDs with different chain lengths have been synthesized. PEG-substituted CDs formed self-threading complexes in aqueous solutions, and the conformational exchange dynamics between self-threading and dethreading could be regulated by its chain length.3.Polymerization of lactonesCDs were found to initiate ring-opening polymerization of some cyclic esters selectively to give a polyester with a CD at the chain end.4.Gel-to-Sol and Sol-to-Gel TransitionsUsing molecular recognition of α-CD, we have successfully constructed a photoresponsive hydrogel system by combination of simple components, α-CD, dodecyl-modified poly(acrylic acid), and a photoresponsive competitive guest, 4,4'-azodibenzoic acid. Gel-to-sol and sol-to-gel transitions occurred repeatedly by repetitive irradiations of UV and visible light. Less

1.超分子聚合物的构建当客体部分共价连接到环糊精（CD）上时，它们形成超分子二聚体、环状菊花链、超分子低聚物和聚合物。t-Boc-肉桂酰胺-α-CD在水溶液中可形成手性超分子聚合物。超分子聚[2]轮烷聚合物和超分子α-，2.超分子聚合物的动力学研究我们研究了一种新的一锅法制备含γ-环糊精的聚轮烷的方法，即在γ-环糊精存在下，通过聚合物链末端的9-蒽基的光环化二聚反应，我们构建了α-蒽基的假轮烷，并在此基础上，合成了含γ-环糊精的聚轮烷。通过动力学控制α-CD穿到轴分子上，轴分子带有吡啶基端帽。连接在轴分子末端的单个取代吡啶基调节α-CD通过它们的速率。两个甲基取代基可以控制a-CD与客体分子形成复合物的程度， ...更多信息 在CD分子进入轴端的面方向的区别。α-环糊精在轴分子的两个站单元上沿一个方向排列，合成了不同链长的聚乙二醇（PEG）取代的环糊精。PEG取代的CD在水溶液中形成自穿线复合物，自穿线与脱穿线之间的构象交换动力学可以通过其链长进行调节。3.内酯类CD的聚合可以选择性地引发某些环酯的开环聚合，得到链端带有CD的聚酯。4.凝胶-溶胶和溶胶-凝胶转变利用α-CD的分子识别，我们成功地构建了一个光响应性水凝胶系统，该系统由简单组分α-CD、十二烷基改性聚丙烯酸和光响应性竞争客体4，4 '-偶氮二苯甲酸组成。通过紫外光和可见光的重复照射，凝胶到溶胶和溶胶到凝胶的转变反复发生。少
