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，可增加半导体树脂、汽车涂料材料配方和眼科镜片等材料的硬度。该技术可通过其高效且可调节的复合生产为许多行业定制。该技术比当前方法具有优势，因为它具有以下特点： a) 节省成本和时间； b) 制造过程中更好的安全性； c) 高性能标准； d) 可持续的生物基系统； e) 作为现有配方工艺替代品的适用性。该 I-Corps 项目基于生物质衍生的紫外线和可见光活性化合物的开发，这些化合物可用于有效的辐射固化以生产高性能材料。鲜艳的色彩在各种化学和生物过程中发挥着至关重要的作用。将这些颜色转化为固化技术具有挑战性，因为它需要合理操纵光化学特性。该技术转化了植物基化合物，可以对紫外线和可见光进行微调，以更高的效率进行辐射固化。目前使用的紫外线固化系统经常遭受表面粘性、表面残留、迁移（在材料表面和空气中）、配方中光引发剂负载量高、固化系统着色、发光二极管 (LED) 表面固化效率低等问题。 ）和/或可见光、固化深度的限制以及环境问题。这些植物基化合物比具有类似发色团的传统化合物具有更优越的光化学、光物理和固化特性。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
