Photoswitchable π-Extended Dithienylethenes with an Attached Molecular Recognition Site

Photoswitchable dithienylethenes have been extended in positions 5 and 5′ with π-systems resulting in absorptions of light with longer wavelengths when electrocyclization and -reversion are carried out. The extended π-systems also improve conductivities potentially. cis-Orientation of the thienyl rings was accomplished by integrating the central double bond into maleic imides. The nitrogen atoms of the imides were substituted by a Hamilton receptor allowing supramolecular binding of complementary guests such as barbiturates. Both, a stiff and a flexible connection between photoswitch and receptor was realized. The resulting photoswitches showed reversible switching over several cycles and were able to bind diethyl barbiturate with binding constants of > 104 m–1.

Design, synthesis and study of a photochromic α,ω-diene: Toward new classes of photoswitchable polymers

A 4,5-dithienylimidazolium salt outfitted with pendant styrenyl groups was synthesized and studied. The salt was found to undergo reversible electrocyclization upon UV irradiation; subsequent exposure to visible light reversed the reaction. Acyclic diene metathesis (ADMET) polymerization of the salt afforded a novel fluorescent polyelectrolyte.
