摘要
宏观超分子组装是超分子化学的一个重要研究方向,构建了超分子基础研究和体相超分子材料应用的桥梁。然而由于超分子短程作用力难以在随机碰撞中调整有序度导致组装结构无序,不利于获得优良的超分子材料性能。目前,精准有序的宏观超分子组装尚未见报道。在此,我们提出两种方案,一种是在体系中引入外场~([1])或化学驱动力~([2]),推动构筑基元自发运动并进入长程相互作用的范围来对匹配程度进行调整,再引入超分子作用力~([3])获得稳定的有序结构。另一种是对随机错配的宏观超分子组装体进行动态组装-解组装控制的自纠错过程~([4])。结合构筑基元的可控运动和超分子组装来构筑三维有序结构,该结构表现出较低的细胞毒性和较好的细胞粘附特性~([5])。我们期望超分子组装这一自下而上构筑三维有序结构的方法可以制备具有复杂化学环境的体相材料,如组织工程支架材料提供一种新的思路。
Macroscopic supramolecular assembly beyond micro-metered scale has been an emerged important research area. The research bridges fundamental research of supramolecular science and applied research of supramolecular materials. However, the macroscopic supramolecular assembly may rely on the contact and collision of building blocks by concussion, which may be difficult to adjust the orderly structures. So far, the precise macroscopic supramolecular assembly has not been reported yet. Here, we propose two solutions. One is to introduce external fields~([1]) or chemical driving force~([2]) into the system, promoting the building blocks spontaneous movement within long-range interactions(such as interfacial tension, capillary force, hydrophilic/hydrophobic interactions) to adjust the matching degree with a stable ordered structure obtained further by the introduction of the supramolecular force~([3]). The other is the self correcting process by multiple dynamic assembly in a repeated way to obtain highly ordered structures~([4]). Three-dimensional ordered structures can be constructed by the controlled movement and supramolecular assembly of building blocks, which show low cytotoxicity and fine cell-adhesion property~([5]). We expect the bottom-up method for constructing ordered 3D structures can provide a new way to prepare bulk materials in complex chemical environment, such as tissue engineering scaffold materials.
