A Conducting Coordination Polymer Based on Assembled Cu₉ Cages

Abstract

We report on a novel highly semiconducting 1D coordination polymer architecture obtained by the reaction of a Cu(II) salt with 2,2'-dipyridyldisulfide under microwave solvothermal conditions. This reaction proceeds with an unusual C-S and S-S bond cleavage of the 2,2'-dipyridyldisulfide ligand. The unprecedented architecture of this coordination polymer consists of a 1D chain formed by the assembling of Cu9 cluster cages. The electrical conductivity behavior of this novel material suggests new perspectives for the use of coordination polymers as electrical conducting materials.

“…This is a very important research field in coordination chemistry as it leads to structurally novel coordination architectures with interesting physical properties [1][2][3]. In this respect, the use of organosulfur compounds containing carboxylate groups can be attractive due to their flexibility and versatile coordinating modes of both sulfur and oxygen atoms and, generating unprecedented coordination frameworks…”

Up to now, a series of transition metal complexes have been found to react with 2,2'-dithiodibenzoic acid (dtdb), giving rise to 1D chains, 2D sheets or 3D network whereby the carboxylate act as monodentate or bidentate donor with or without cleavage of the S-S bond [9].…”

The Research Progress on the Synthesis and Application of Microporous Coordination Polymers

“…Liu et al [16] 8 ], respectively for the three-dimensional, two-dimensional and one-dimensional structure, the size of the resulting product is between 0.01~0.5mm. Delgado et al [17] in the power of 600W microwave irradiation, the reaction mixture is heated to 140°C within 20min and maintain 2h, got a one-dimensional coordination polymer connected by a cage-like Cu 9 {[Cu 9 (C 5 H 5 NS) 8 (SH) 8 ](BF 4 )} n , which has good conductivity, is one of the few conductive coordination polymers.…”
