Ultrafast Transient Absorption

Ultrafast transient absorption spectroscopy reveals new excited-state dynamics following excitation of trans-azobenzene (t-Az) and several alkyl-substituted t-Az derivatives encapsulated in a water-soluble supramolecular host–guest complex.

Ultrafast Transient Absorption Spectroscopy

Decoration of Ag-ultrathin Ni-MOF onside Cu2O was firstly fabricated. The charge-transfer dynamics at heterostructure was in-depth revealed by ultrafast transient absorption spectroscopy. NH3 yield rate (4.63 μg h-1 cm-2) with...
