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.

I-Corps项目更广泛的影响/商业潜力是开发可用于光固化系统的环保化合物。光固化是一种紫外线（UV）交联技术，用于增加材料的硬度，包括半导体树脂，汽车涂料材料配方和眼科镜片。该技术可通过其高效和可调的化合物生产为许多行业定制。与目前的方法相比，该技术具有以下优点：a)节省成本和时间；B)生产过程中更好的安全性；C)高绩效标准；D)可持续的生物基系统；e)替代现行配方工艺的适用性。I-Corps项目的基础是开发生物质衍生的紫外线和可见光活性化合物，这些活性化合物可用于高效辐射固化，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关键作用。将这些颜色转化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质。这项技术转化了基于植物的化合物，可以对紫外线和可见光的辐射固化进行微调，效率更高。目前使用的UV固化系统通常存在表面粘连、表面残留、迁移（在材料表面和进入空气中）、配方的高光引发剂负载、固化系统着色、使用发光二极管（led）和/或可见光进行表面固化的效率低下、固化深度的限制以及环境问题。与具有相似发色团的传统化合物相比，这些植物基化合物具有优越的光化学、光物理和固化性能。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
