Photochromism of Arylchromenes: Remarkable Modification of Absorption Properties and Lifetimes of o-Quinonoid Intermediates
摘要:
A significant pi-conjugation in 6- and 7-arylchromenes manifests dramatically in the absorption properties of their photogenerated o-quinonoid intermediates. This in conjunction with facile synthesis via Suzuki coupling may render a myriad of photochromic arylchromenes with wide-ranging spectrokinetic properties readily accessible.
