Chiral discrimination in photochromic helicenes.

Tony J Wigglesworth1, David Sud, Tyler B Norsten, Vikram S Lekhi, Neil R Branda.   

Abstract

A photoresponsive dithienylethene derivative bearing chiral pinene-based arms underwent a stereoselective photoinduced cyclization reaction to produce greater than 98% of a single diastereomer. The magnitude of the optical rotation changed as much as Delta[alpha]373 = 8698 degrees upon alternate irradiation with 400 nm and greater than 434 nm light.
