The Mei Research Group at Purdue University bridges the gap between fundamental discovery and real-world innovation. Integrating chemistry, materials science, and engineering, our research advances organic semiconductors and conductors—materials with transformative potential for printed electronics, bioelectronics, and related technologies. Our work spans both immediate industrial impact and long-term visionary pursuits.

In this seminar, I will highlight two ongoing efforts: Electrochromic Technologies and Artificial Vision Systems (Organic Eyes). Both involve the precise manipulation of light, color, ions, and electrons. Through Ambilight Inc., our discoveries in flexible electrochromic thin films have been commercialized using roll-to-roll manufacturing, revolutionizing applications in electric vehicles and consumer electronics. I will present two examples illustrating how an academic laboratory can effectively generate fundamental knowledge that benefit market-ready technologies. Inspired by biological vision, our second research direction—Organic Eyes—aims to emulate the function of the human visual system and the brain. While practical realization remains challenging, this work exemplifies our commitment to frontier exploration.

To illustrate our broader approach, I will discuss the journey of n-doped poly(benzodifurandione) (n-PBDF), a polymer discovered in our laboratory, tracing its path from initial discovery and scalable synthesis to applications in flexible circuits and bioelectronics. This case study embodies our philosophy: coupling curiosity-driven inquiry with mission-driven innovation. By merging these two dimensions, we transform foundational science into technologies that advance society.
