Characterization of the Luminescent *Cu(CN)2Br2- Exciplex

Structure and catalytic activity of a penta-silver supramolecular cluster through hydrogen bonding and 2,2′-bipyridine

“…The emission band at 430 nm resembles that of CuCN [52] which is assumed to arise from transitions from the lowest excited-triplet state to the ground state. Life time studies of soluble Cu(1)-cyano species have suggested that emission is usually a phosphorescence phenomenon [53,54]. The low energy …”

Synthesis, Crystal Structures and Fluorescence Properties of Two d10 Metal Coordination Polymers with Flexible Bis(benzimidazolyl)alkane Ligands

“…Complex 2 shows an emission at 330 nm upon excitation at 280 nm; compared with the free L 2 ligand (λ ex max = 270 nm, λ em max = 370 nm), the emission is blue-shifted by 40 nm for 2. The bands can be assigned as the metal-to-ligand charge transfer with electrons being transferred from the Cu(I) center to the unoccupied π * orbitals of the cyanide groups [23,24].…”

In vitro and in vivo antitumor activity of novel 3D-organotin supramolecular coordination polymers based on CuCN and pyridine bases

“…The emission spectra of 1 and 2 are assumed to arise from transitions from the lowest excited-triplet state to the ground state. Life time studied of soluble Cu(I)-cyano species have suggested that emission is usually a phosphorescence phenomenon [39,40]. The emission bands centered at 400e460 nm corresponds to single-metal-centered (MC) transitions of the type 3d 10 / 3d 9 4s 1 and 3d 10 / 3d 9 4p 1 on the Cu(I) center, while the bands at 485 nm and 530 nm may be attributed to metal to ligand charge transfer (MLCT).…”
