Photoswitchable diacylglycerols enable optical control of protein kinase C. [PDF]

, 2016
Increased levels of the second messenger lipid diacylglycerol (DAG) induce downstream signaling events including the translocation of C1-domain-containing proteins toward the plasma membrane. Here, we introduce three light-sensitive DAGs, termed PhoDAGs,

Immense magnetic response of exciplex light emission due to correlated spin-charge dynamics

, 2016
As carriers slowly move through a disordered energy landscape in organic semiconductors, tiny spatial variations in spin dynamics relieve spin blocking at transport bottlenecks or in the electron-hole recombination process that produces light. Large room-
