Hierarchical Self-Organization of Photonic Materials

这一奖项授予亨特学院的查尔斯·德雷恩，其目标是发展卟啉类化合物的超分子化学。卟啉、酞菁和卟嗪是被称为卟啉类化合物的环系的一部分。它们非常坚固，具有广泛的物理、化学和光子特性，可以通过多种不同的方式进行微调，因此是现实世界应用中材料的理想选择。将构建包含多种类型的这些环系的材料，并将特别强调这些环系的三维结构。PI提出了三个研究目标：非均相混合物的自组装，类卟啉在胶体和薄膜中的自组装，以及自组装阵列和自组织纳米颗粒在选定的表面上的沉积。我们将研究这些材料的光子性质，这将使我们能够研究多个组件自组织和自组装成多功能分级系统的基本原理。最终，这将导致更好地理解自然系统中的这些过程，并将为构建具有设计功能的复杂超分子材料提供路线图。除了这门科学的好处外，PI还将使用“垂直整合”的方法训练学生，每个学生从头到尾检查一道题。这包括合成、表征、表面科学和评估，允许学生接受非常广泛的培训。此外，PI将把代表人数不足的群体的学生，包括妇女和少数族裔，纳入研究环境。PI有一个针对少数族裔学生的积极、积极的招生计划。

This award to Charles Drain of Hunter College has as its goal to develop the supramolecular chemistry of porphyrinoids. Porphyrins, phthalocyanines and porphyrazines are part of a family of ring systems referred to as porphyrinoids. They are very robust with a broad range of physical, chemical, and photonic properties that can be fine-tuned in a number of different ways and as a result are ideal for materials in real-world applications. Materials containing multiple types of these ring systems will be constructed and there will be special emphasis on the 3-dimensional structures of these systems. The PI has proposed three research objectives: self-assembly of heterogeneous mixtures of porphyrinoids, self-organization of porphyrinoids into colloids and films, and deposition of self-assembled arrays and self-organized nanoparticles on selected surfaces. The photonic properties of these materials will be examined and this will allow study of the fundamental principles of self-organization and self-assembly of multiple components into multifunctional hierarchical systems. Ultimately, this will lead to a better understanding of these processes in natural systems, and will afford a roadmap for the construction of complex supramolecular materials with designed functionality.Broader Impacts. In addition to the benefit of the science, the PI will train students using a "vertically integrated" approach where the students will each examine a problem from beginning to end. This includes synthesis, characterization, surface science and evaluation allowing for the students to be extremely broadly trained. Further, the PI will bring students from underrepresented groups, including both women and minorities, into the research setting. The PI has a vigorous, proactive recruiting program for minority students.
