Solvation Dependent Redox-Gated Fluorescence Emission in a Diarylethene-Based Sexithiophene Polymer Film

Bringing the functionality of molecular systems to interfaces while avoiding cross-talk and loss of function is essential to realize their full potential. The photochromic and -physical properties in polymer films formed from a terthiophene-diarylethene bifunctional monomer are lost due to aggregation but restored by solvent swelling, recovering electro- and photochromic switching as well as on/off control of fluorescence with memory.
