Deconjugative Photoisomerization of Cyclic Enones

Journal of the American Chemical Society
The deconjugative isomerization of α,β-unsaturated carbonyl compounds enables regioisomeric products to be forged with simultaneous Umpolung of alkene reactivity. Although highly enabling, the endergonic nature of the net process coupled with governing regioselectivity outcomes, renders it challenging.

Modulating the macroscopic anisotropy of liquid crystalline polymers by polarized light

Responsive Materials
Photoalignment technology is serving as an emerging technology for programming liquid crystalline polymer (LCP) materials due to its advantages including noncontact, high resolution, spatial control, programmability, and high efficiency.

Synthesis of N-acetyl diazocine derivatives via cross-coupling reaction

Beilstein Journal of Organic Chemistry
Diazocines are photoswitches derived from azobenzenes by bridging the two phenyl rings in ortho position with a CH2CH2 group forming an eight membered (diazocine) ring.
