The Macromolecular, Supramolecular, and Nanochemistry Program supports Professor Nancy Goroff of the State University of New York at Stony Brook, to prepare novel conjugated polymers and graphitic structures for optoelectronic applications. The focus of this work is to create new high-carbon or all-carbon materials with unusual structures that impart unique and desirable physical, chemical, and electronic properties. Careful characterization determines the molecular and supramolecular structure for each, and through collaborations with analytical and physical chemists, the electronic and optical properties and possible applications for these materials are explored. The research involves the use of poly(diiododiacetylene) as a precursor to ordered high-carbon materials, including the linear carbon allotrope carbyne. Also, the preparation of new ordered polymers from other diynes, triynes, and tetraynes. Poly(dibromodiacetylene) is a primary target for a highly planar conjugated polymer with a broader absorption spectrum and greater photostability than poly(diiododiacetylene), and as a precursor to other materials via post-polymerization modification.This research provides methods for preparing new carbon-based semiconducting materials. One application for these materials is in thin-film solar cells. A key goal is to find new carbon-based semi-conductors that can absorb a greater percentage of the visible and infrared solar spectrum, increasing the efficiency of the resulting solar cell. These materials can also be prepared completely free of toxic metal contaminants such as palladium or zinc. New materials are critical to the development of the important field of optoelectronics. A major component of the work involves collaborative research, which brings together scientists with different expertise and research focus, increasing communication across disciplinary boundaries. Graduate students and undergraduates gain experience in making new materials and studying their properties, skills that can be used in industries as varied as pharmaceuticals and electronics. Professor Goroff is deeply involved in outreach activities, notably through the Alan Alda Center for Communicating Science, housed in the School of Journalism at Stony Brook. She serves on the Steering Committee for the Alda Center, and acts as a judge for the Center's annual Flame Challenge, a competition that has attracted international attention and led to significant insights about how to communicate scientific ideas most effectively to children.

大分子，超分子和纳米化学计划支持斯托尼布鲁克的纽约州立大学的Nancy Goroff教授，以制备用于光电应用的新型共轭聚合物和石墨结构。 这项工作的重点是创造新的高碳或全碳材料，具有不寻常的结构，赋予独特的和理想的物理，化学和电子性能。仔细的表征确定了每种材料的分子和超分子结构，并通过与分析和物理化学家的合作，探索了这些材料的电子和光学性质以及可能的应用。 该研究涉及使用聚（二碘二乙炔）作为有序高碳材料（包括线性碳同素异形体碳炔）的前体。此外，从其他二炔、三炔和四炔制备新的有序聚合物。 聚二溴二乙炔是一种具有比聚二碘二乙炔更宽的吸收光谱和更高的光稳定性的高度平面共轭聚合物的主要目标，也是通过聚合后改性制备其他材料的前驱体，本研究为制备新型碳基半导体材料提供了方法。 这些材料的一个应用是薄膜太阳能电池。一个关键目标是找到新的碳基半导体，可以吸收更大比例的可见光和红外太阳光谱，提高太阳能电池的效率。 这些材料也可以完全不含有毒金属污染物如钯或锌来制备。 新材料是光电子学这一重要领域发展的关键。 这项工作的一个主要组成部分是合作研究，将具有不同专业知识和研究重点的科学家聚集在一起，增加跨学科的沟通。研究生和本科生在制造新材料和研究其特性方面获得经验，这些技能可用于制药和电子等各种行业。戈罗夫教授深入参与外联活动，特别是通过设在斯托尼布鲁克新闻学院的艾伦·阿尔达传播科学中心。 她在阿尔达中心的指导委员会任职，并担任该中心年度火焰挑战赛的评委，该比赛吸引了国际关注，并就如何最有效地向儿童传达科学思想提出了重要见解。
