This is my first first-author paper in grad school! We studied the photochromism and mechanochromism of a linear naphthopyran. Many thanks to Prof. @Maxwell_Robb and everyone @TheRobbGroup for the guidance and support! And, thanks to my wonderful mentor @Molly__McFadden !

Appearing today in @ChemicalScience, Yan Sun (@YanSun21) and coworkers in @TheRobbGroup illustrate that a polarizing dialkylamine substituent enables photochromic and mechanochromic behavior from a typically inert linear naphthopyran. Congrats to all! 🎉 doi.org/10.1039/D3SC03790H

I defended my thesis today! I am so happy, and I have to thank my wonderful friends and collaborators, my fantastic committee (Dennis, Sarah, and Greg) and most of all my phenomenal advisor Max, who has been my ardent supporter, mentor, and friend throughout this process.

Very excited to share our latest work on naphthopyran mechanochemistry! It’s been a team effort and I’m beyond proud of and grateful to my wonderful coauthors. Go check out the photos of the gorgeous colors we get from this new mechanophore! 🧪
