Hierarchical Self-Organization of Photonic Materials

该奖项授予亨特学院的 Charles Drain，其目标是开发类卟啉的超分子化学。 卟啉、酞菁和卟啉是称为类卟啉的环系统家族的一部分。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，因此是实际应用中材料的理想选择。 将构建包含多种类型的这些环系统的材料，并将特别强调这些系统的 3 维结构。 该项目负责人提出了三个研究目标：类卟啉异质混合物的自组装、类卟啉自组织成胶体和薄膜、以及在选定表面上沉积自组装阵列和自组织纳米颗粒。将检查这些材料的光子特性，这将允许研究自组织和自组装多个组件到多功能分层系统的基本原理。最终，这将有助于更好地理解自然系统中的这些过程，并为构建具有设计功能的复杂超分子材料提供路线图。更广泛的影响。除了科学的好处之外，PI 还将使用“垂直整合”的方法来培训学生，每个学生将从头到尾检查一个问题。 这包括合成、表征、表面科学和评估，使学生能够接受极其广泛的培训。 此外，PI 还将把来自代表性不足群体（包括女性和少数民族）的学生带入研究环境。 PI 为少数族裔学生制定了积极主动的招生计划。

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.
