predominantly trans-cis photoisomerization. This studies will
provide useful information in understanding the photochem-
istry of conjugated molecules and linear polyene bound bio-
logical photoreceptors. It also provide a new direction in de-
signing and developing novel materials for biological and or-
ganic electronic applications.
