Most photochemical reactions obey Kasha's rule, i.e., they take place from the lowest excited state of a given multiplicity. This implies that the excess of energy after light excitation is lost in the course of relaxation to the lowest excited state. Therefore, molecules that are able to use higher excited states for anti-Kasha photochemistry can lead to more efficient light-energy...
Nitrogen makes up 78% of the Earth’s atmosphere. Ammonia derived from N2 and fossil H2 in the Haber-Bosch process represents the main source of nitrogen compounds used in fertilizers as well as a base chemical for the synthesis of value-added products. In order to access a more diverse range of N-containing chemicals without relying on NH3 as an intermediate,...
Introduction
In spite of the attractive interest of a-MoS$_3$ based nanomaterials for numerous applications in catalysis and energy, the amorphous nature of the MoS$_3$ phase makes it challenging to control and understand its chemical reactivity[1]. In particular, the type of the structural building unit such as Mo3 triangular[2,3] vs. Mo chain[4,5] is still debated[6], while the...
The photocatalytic [2+2] cycloaddition of cyclic enones has recently received renewed attention. It was discovered that it can be catalyzed by chiral Lewis acids (1,3,2-oxazaborolidines) to yield a variety of bicyclic products with high enantioselectivity [1,2]. The key to this reaction is a redshift of the bright UV absorption band of the enone caused by the Lewis acid, which allows for a...
Green Fluorescent Protein (GFP) is widely used in bioimaging due to its remarkable fluorescent properties. GFP is also found to undergo oxidative photoconversion, which is accompanied by electron transfer from the excited state of the GFP chromophore anion to oxidants of various origin. Recently, we have shown that light-induced electron transfer from GFP is mediated by a single vibrational...
