The broader impact/commercial potential of this I-Corps project is the development of eco-friendly compounds that can be used in photocuring systems. Photocuring is a ultraviolet (UV)-crosslinking technique to add firmness to materials including resins for semiconductors, material formulations for automotive coatings, and ophthalmic lenses. This technology is customizable for many industries through its efficient and tunable compound production. The technology has advantages over current methodologies as it features: a) cost and time savings; b) better safety during manufacturing; c) high performance standards; d) sustainable biobased systems; and e) suitablility as a substitute for current formulation processes.This I-Corps project is based on the development of biomass-derived UV and visible light active compounds that can be employed for efficient radiation curing to produce high performance materials. Vibrant colors play a critical role in various chemical and biological processes. Translating these colors to curing technology is challenging as it requires rational manipulation of photochemical properties. This technology translates plant-based compounds that can be fine-tuned for radiation curing with both UV and visible light with a higher efficiency. Currently employed UV cure systems often suffers from surface tack, surface residue, migration (both at the surface of the material and into the air), high photoinitiator loading for formulations, coloring of the cured system, inefficient surface cure with light emitting diodes (LEDs) and/or visible light, limitations on cure depth, and environmental concerns. These plant-based compounds have superior photochemical, photophysical and curing properties than the conventional compounds featuring similar chromophores.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是开发可用于光电系统的环保化合物。光电是一种紫外线（UV） - 跨链接技术，可为包括半导体树脂，汽车涂层的材料配方和眼镜透镜增加材料。通过其高效且可调化的复合生产，这项技术可为许多行业定制。该技术比当前方法具有优势：a）成本和时间节省； b）制造过程中更好的安全性； C）高性能标准； d）可持续生物基的系统； e）适用于当前配方过程的替代性。该I-Corps项目基于生物质衍生的紫外线和可见光的光活性化合物的开发，可用于有效辐射固化以生产高性能材料。鲜艳的颜色在各种化学和生物过程中起着至关重要的作用。将这些颜色转换为固化技术是具有挑战性的，因为它需要合理地操纵光化学性能。这项技术翻译了基于植物的化合物，可以用紫外线和可见光来微调辐射固化，并具有更高的效率。目前使用的紫外线治疗系统通常患有表面钉，表面残留，迁移（在材料的表面和空气中），高光吸剂负载，用于配方，固化系统的着色，效率低下的表面固化，带有光发射二极管（LED）和/或可见光，限制了对环境深度和环境问题的限制。这些基于植物的化合物具有优越的光化学，光体物理和固化特性，其特性比具有类似发色团的常规化合物具有出色的光化化合物。该奖项反映了NSF的法定任务，并且使用基金会的智力优点和更广泛的影响审查标准，认为通过评估值得支持。
