For a direct quantitative investigation of the Csp(2)-Csp(2) reductive elimination rate within a catalytic cycle, a novel oxidative coupling system in the presence of a Ni catalyst and desyl chloride as the oxidant is devised. The reaction progress p

This paper describes the photo-induced switching of conductance in tunneling junctions comprising self-assembled monolayers of a spiropyran moiety using eutectic Ga-In top contacts. Despite separation of the spiropyran unit from the electrode by a lo

Laser flash photolysis (Nd:YAG laser, 355 nm, 35 mJ, 150 ps) of dimethyldiazirine and dimethyldiazirine-d6 produces dimethylcarbene (DMC) and dimethylcarbene-d6 (DMC-d6), respectively. The carbenes were trapped with pyridine to form ylides which abso

Transient resonance Raman spectroscopy has been used to probe the vibrational dynamics of the heme active site of deoxyhemoglobin during photoexcitation. Near UV pulses of approximately 35 ps in duration were used to both excite the sample and genera

We have synthesized a family of bis-enediynes by two complementary Pd/Cu-catalyzed Sonogashira cross-coupling methods. One is a modified Sonogashira reaction between the TMS-protected tetraalkyne 20 (or 21) and various aromatic bromides to afford bis

The rate of electron transfer from BPh{sup {sm bullet}{minus}} to Q{sub A} (k{sub 1}) was determined at 14, 35, 113, and 298 K in reaction center protein from Rhodobacter sphaeroides R-26 in which the native Q{sub A}, UQ{sub 10}, was removed and acti
