Synthesis and photochromic properties of a dithia-dithienylethenophane
MK Hossain, M Takeshita, T Yamato - Tetrahedron letters, 2005 - Elsevier
The thermally irreversible photochromic compound dithia-dithienylethenophane was
synthesized, which is the first example of a dithienylethene bridged with benzene ring and
due to the fixation to the photoactive anti-conformation the quantum yield for the
photocyclization reaction became higher than that of the corresponding nonbridged type
dithienylethene.
