Article
The aqueous equimolar reaction of Ag(I) ions with the thionucleoside enantiomer (-)6-thioguanosine, ((-)6tGH), yields a one-dimensional coordination polymer {Ag(-)tG}n, the self-assembly of which generates left-handed helical chains. The resulting helicity induces an enhanced chiro-optical response compared to the parent ligand. DFT calculations in...
Conference Paper
In this work, silver nanoparticles (AgNPs) have been synthesised via friendly method without adding any reducing agents or exposure to artificial light such as a UV lamp. The method is based on preparing highly stable silver(I):guanosine hydrogel with stoichiometry 1:1. None of monovalent cations were used in this method to induce the formation of...
Article
In this work, active and stable catalyst for the dehydrogenation reaction of dimethylamine borane (DMAB) in solvent-free medium at room temperature has been prepared. The method is based on preparing in-situ monodispersed gold nanoparticles (AuNPs) by reducing the one dimensional polymer of gold(I):6-thioguanosine hydrogel by DMAB; which acts as re...
Article
In this work, a new class of host-guest polymer has been synthesised and characterized based on preparation Au(I):6-thioguanosine hydrogel (host) that is carrying gold nanoparticles AuNPs (guest). The morphology of the formed polymer was investigated with Atomic Force Microscopy (AFM) technique. The images displayed converting the linear polymer of...

In this work one-dimensional (1D) triplex polymer of silver (I): mixture nucleosides of cytidine and 8-bromogua-nosine was synthesised. The polymer showed high stability due to the presence Ag(I) ions in the structure of the polymer in addition to the stability that produces from the effect of Hoogsteen hydrogen bonding in the triplex CGC. Atomic F...

Advances in bottom-up material design have been significantly progressed through DNA-based approaches. However, the routine integration of semiconducting properties, particularly long-range electrical conduction, into the basic topological motif of DNA remains challenging. Here, we demonstrate this with a coordination polymer derived from 6-thiogua...
