Luminescence detection and photodimerization of 1,3-dimethyluracil coordinated to copper(I)

摘要

1,3-Dimethyluracil (DMU) forms a complex with copper(I) iodide which shows a green luminescence at lambda(max) = 505 nm. With PF6- counterions a photoactive Cu(I)DMU complex is generated which shows a long-wavelength absorption at lambda(max) = 335 nm. Light absorption by this band leads to a dimerization of DMU to its cyclobutane dimer. [References: 26]
