Controlling polymorphism in ordered molecular solids through manipulation of processing method has been rarely addressed despite its significance in creating assembled molecular materials with desired functions. We here report a hyperbranched liquid-crystalline polymer that showed variable lamellar smectic phases, depending on the processing methods by regulation of the kinetics involved assembly process to control the molecular packing arrangement in different lamellar arrays. The processing-dependent polymorphism enabled multicolored light emission of the liquid-crystalline polymer including cyan, green, and yellow light, showing variant degree of bathochromic shift with respect to the blue fluorescence in highly dilute solution. With a good correlation between the processing methods, hierarchically assembled structures, and light emission properties of the hyperbranched liquid crystalline polymer, it would have broad implications in pathway-dependent supramolecular self-assembly and provide a guidance for the development of adaptive functional materials in different situations.

可变发光的超支化液晶聚合物的加工相关层状多态性

尽管通过加工方法的控制来控制有序分子固体中的多态性，尽管在产生具有所需功能的组装分子材料中具有重要意义，但很少涉及。我们在这里报告了一种超支化液晶聚合物，该聚合物表现出可变的层状近晶相，这取决于通过调节涉及组装过程的动力学来控制不同层状阵列中的分子堆积排列的加工方法。依赖于处理的多态性使得液晶聚合物能够发出多色发光，包括青色，绿色和黄色光，相对于高度稀释的溶液中的蓝色荧光显示出不同的红移程度。在处理方法，层次结构组装结构之间具有良好的相关性，
