Polymer dispersed self-assembling small molecules

目前，由氢键和p层相互作用介导的超分子组装研究是一个活跃的研究领域。控制这种组装以提供最佳形态（例如，用于喷墨应用）是我们研究具有不同长度烷基侧链的氨基甲酸酯的目的。这些分子在特定溶剂中也会形成有机凝胶。我们还报道了由于苝通过p-stacking自组装而形成的端盖聚二甲基硅氧烷的胶束和囊泡组装。在这里，自组装分子在聚合物基体中形成相分离的聚集体结构。本提案旨在研究这些自组装分子分散在聚合物复合材料中的形态，并探索控制这些形态的方法。虽然人们对聚合物分散液晶的形态进行了研究，但据我们所知，涉及自组装小分子的液晶形态迄今尚未进行探索。我们认为没有研究报道自组装分子分散在基质中的位置，以及自组装如何受到干扰或促进新的形态设计。我们正在开展这样的研究。小分子聚合物凝胶至今未见报道。因此，这是一个新的和新颖的研究领域，可能会导致广泛的应用和相关研究。我们相信，我们正在开辟一个新的研究方向。因此，(1)自组装的小分子将分散在聚合物基质中，我们将研究小分子的分散如何受到氢键、p堆叠或类似相互作用的影响。将研究其基本的分子机制。(2)利用适合光电和光子应用的功能分子设计聚合物两亲体系，并研究控制其自组装形态的方法。(3)还将制备含有这种自组装分子的聚合物凝胶。

Studies on supramolecular assembly, mediated by e.g., hydrogen bond and p-stacking interactions is an active area of research at this time. Controlling such assembly to provide optimum morphology (e.g., for inkjet applications) was the purpose of our studies on carbamates with alkyl side chains of different lengths. These molecules also form organo-gels in specific solvents. We also reported the micellar and vesicular assembly of perylene end-capped poly (dimethyl siloxane) due to the self-assembly of the perylene via p-stacking. Here the self-assembled molecules form phase separated aggregate structures in the polymer matrix This proposal aims at studying the morphologies of polymer composites in which these self-assembling molecules are dispersed and at exploring the means of controlling these. Although there have been studies on the morphology of polymer dispersed liquid crystals, to the best of our knowledge, those involving self-assembling small molecules have not been explored so far. We believe that no study has been reported where self- assembling molecules are dispersed in the matrix, and how the self-assembly is perturbed or facilitates novel morphological designs. We are initiating such studies. Polymer gels with small molecules have never been reported so far. Thus, this is a new and novel area of research, which could lead to a wide range of applications and related studies. We believe that we are thus opening up a new direction of research. Thus, (1) Self-assembling small molecules will be dispersed in a polymer matrix and we will study how the dispersion of the small molecule is affected by the hydrogen bond, p-stacking or similar interactions. The basic molecular mechanisms will be studied. (2) Polymeric amphiphilic systems, using functional molecules appropriate to optoelectronic and photonic applications will be designed and means to control their self-assembled morphologies will be studied. (3) Polymer gels incorporating such self-assembling molecules will also be prepared.
