The binding of donor-acceptor Stenhouse adducts (DASAs) bearing hydrogenbond recognition groups by Hamilton-type receptors significantly influenced their photoswitching properties by altering thermal barriers to isomerization. The thermal barrier between the most stable linear isomer and the photo-generated isomer is lowered on binding to a receptor, and this barrier is crucial for switching properties. The thermal isomerization was shown to proceed via a stepwise linear-enol-keto mechanism in DMSO where the barrier to tautomerisation is within 2 kJ•mol-1 of that of the rate-determining step, which may be important for analyzing switching properties.Read less <
