Room-Temperature Fluorescence of Substituted Copper(I) Benzenethiolates.
Abstract
The room-temperature fluorescence of copper(I) complexes of substituted benzenethiols is discussed. The fluorescence can be excited over a wide range of excitation wavelengths with no change in the position of the emission band which occurs at 590 + or - 5 nm. The maximum emission is observed at an excitation wavelength of 470 nm which corresponds to the maximum in the excitation spectrum. The observed transition is assigned as the pi*-d type which is inverse of the lowest energy charge-transfer transition where the Cu(I) ion d-electron is excited to a pi* orbital of the ligand. The complexes interact with pyridine to form loosely bound adducts which exhibit yellow to green fluorescence. (Author)
