Materials with chemical and physical properties that can be optically modulated are of high interest for new optical recording systems, holographic rewriteable media, drugdelivery applications, biosensors, and advanced microscopic techniques.[1] Photochromic compounds readily lend themselves to this purpose, as they can be reversibly converted by light between two states with different spectroscopic properties.[2] This attribute can then ...
