    • Abstract

       

      An oligo-(p-phenyleneethynylene) (OPE)-based water repellent, luminescent and electrically conducting Mgmetal-organic framework (MOF) {[Mg$_3$(OPE-C$_{18}$)$_3$(H$_2$O)$ _2$]$\cdot$2DMF}$_n$ (1) has been synthesized and structurally characterized. Ultra-high water contact angles (170$^ {\circ}$) and isotropic semiconductivity have been observed in 1 in both crystalline and thin-film states. DFT calculations support a ‘through bond’ mode of electrical conductance. To the best our knowledge, this report is only the second instance of a superhydrophobic and electrically conducting luminescent bulk MOF.
