Study on The Properties of Bifunctional Fused Molecule Consisted of Spiropyran and Fluorescein Units Using Ultrafast Spectroscopy
the ring-closed spiropyran form (SP) and the ring-opened merocyanine form (ME). In order to get more applications
the fluorescence of spiropyran needs to be enhanced. To produce a fused bifunctional molecule with full conjugated configuration and conformation
we synthesized a fused molecule with both functional groups of spiropyran and fluorescein. There exist many kinds of configuration and conformation in these molecules
but only the conjugated one makes sense. Femtosecond transient absorption ultrafast spectroscopy is used to characterize this fused molecule. The experiments demonstrate that there is a part of fully conjugated configuration and conformation
which can enhance the fluorescence intensity.
