Abstract

Abstract : The interaction of Zn 2+ ions with pure nucleobases guanine and cytosine under alkaline conditions leads to the formation of nanoscale metal–organic nanofibers and nanoflowers with excellent photocatalytic activity for the degradation of organic pollutant dyes. Abstract : The formation of hybrid metal–organic nanoscale materials using basic biological building blocks is highly appealing due to the rich functional group chemistry as well as green and benign environment offered by biomolecules which can significantly reduce the energy consumption in manufacturing processes. In this contribution, the spontaneous formation of crystalline hybrid organic–inorganic nanoscale materials such as nanofibers and nanoflowers through the supramolecular interaction of Zn 2+ and unsubstituted nucleobases is reported. The interaction of cytosine and guanine with Zn 2+ ions in alkaline medium led to the formation of metallogels with nanofibrous morphology. Surprisingly, the addition of Zn 2+ ions to a solution containing a mixture of cytosine and guanine led to the formation of flower shaped crystalline coordination polymer particles. The catalytic activity of the three materials has been exploited for the photocatalytic degradation of environmental pollutant organic dyes such as methylene blue and methyl orange.
