Structural Characterization and Luminescence Behavior of a Silver(I) 1D Polymeric Chain Constructed via a Bridge with Unusual 4,5-Diazospirobifluorene and Perchlorate

Abstract

A new polymeric silver complex, [Ag(2)(L(2))(ClO(4))(2)] (L = 4,5-diazospirobifluorene), has been synthesized and shown to exhibit interesting luminescence properties in a single crystal. Structural analysis reveals a one-dimensional chain, which contains a [Ag(2)(L(2))](2+) dimer bridged with ClO(4)(-). The Ag...Ag distances are 2.776(1) and 4.575(1) A incorporated by two L ligands and by a ClO(4)(-) bridge, respectively.

Synthesis, structure, properties and a theoretical study of [ZnCl2(4,4'-bipy)]n

“…On the basis of this geometry, time-dependent DFT (TDDFT) calculation using the B3LYP functional was performed. 17,18 Figure 4 depicts the features of the lowest unoccupied (LUMO) and the highest occupied (HOMO) frontier orbitals of 1. Apparently, the electron density of the singlet state for the HOMO is located on the chlorine atoms, while that of the LUMO is distributed on the 4,4'-bipy moiety; this suggests that the emission band of 1 can be attributed to the ligand-to-ligand charge transfer (LLCT) (from the HOMO of chlorine atoms to the LUMO of the 4,4'-bipy moiety).…”

Design and synthesis of a novel d10–d10 mixed metal-based polymer with superior luminescent properties to select Ca2+ and Zn2+

“…The transverse and lengthways parallel copper chains are arrayed in a plane respectively (see To our best knowledge, the (μ 3 , η 2 ) bridging mode of CN was rarely observed and it also appeared in the mixed-valence copper complex [Cu 3 (CN) 4 [16]. Similar to other copper or silver compounds [17][18][19][20][21], the polymer exhibits copper-copper and silver-silver interactions with an M-M distance of 2.550 Å and 3.011 Ǻ, respectively. Considering the M-M interactions, from a topological view (Fig.…”
