摘要

Detailed H-1 NMR kinetic investigations of the photochemical and thermal behaviour of a recently described poly-photochromic molecule including both dithienylethene and naphthopyran groups are reported. The combination of two photochromic moieties allows the selective controlled extension of the conjugated pi-electron system and the modulation of the absorption behaviour between similar to 380 to similar to 750nm. It is shown that the two photochromic entities are coupled and do not behave independently. Copyright (c) 2007 John Wiley & Sons, Ltd.
