Detailed 1H 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 ∼380 to ∼750 nm. It

[reaction: see text] The photochromic performance of a hybridsystem connecting naphthopyran and dithienylethene was investigated, and the photochemistry of eight different isomers was explored by choosing an appropriate wavelength of light.
