An unprecedented polyoxometalate-based 1D double chain compound with opposite charges enables conductivity improvement

A POM-based one-dimensional (1D) chain compound, {BW12O40[Cu(2,2 '-bipy)(2)](2)[Cu(2,2 '-bipy)(H2O)]}{BW12O40[Cu(2,2 '-bipy)(2)][Cu(2,2 '-bipy)(H2O)(2)]}center dot 7H(2)O, has been synthesized and structurally characterized, which represents an unprecedented 1D double chain structure with opposite charges. In contrast to common POMs, this compound exhibits a relatively high electrical conductivity of 1.17 x 10(-9) S cm(-1) at 25 degrees C. In addition, its semiconducting properties have also been investigated by application of photoelectrochemical sensing of H2O2.

Automated summary
