A nucleobae-inorganic hybrid polymer consisting of copper bis(phosphopentamolybdate) and cytosine

摘要

A nucleobae-inorganic hybrid polymer built from P_2Mo_5O_(23) and Cu(II)-cytosine subunits has been prepared; X-ray crystal structure analysis reveals the cytosine molecules weakly coordinate to copper(II) and connect the P_2Mo_5O_(23) subunit through hydrogen bonds to form extended 2D networks with complicated hydrogen bonding modes; a bathochromic shift, compared to free cytosine, can be observed in the fluorescence spectra of the hybrid polymer.
