Direct Formation of Sub-Micron and Nanoparticles of a Bioinspired Coordination Polymer Based on Copper with Adenine

Abstract

Abstract:We report on the use of different reaction conditions, e.g., temperature, time, and/or concentration of reactants, to gain control over the particle formation of a bioinspired coordination polymer based on copper(II) and adenine, allowing homogeneous particle production from microto submicro-, and up to nano-size. Additionally, studies on this reaction carried out in the presence of different surfactants gives rise to the control of the particle size due to the modulation of the electrostatic interactions. Stability of the water suspensions obtained within the time and pH has been evaluated. We have also studied that there is no significant effect of the size reduction in the magnetic properties of the Cu(II)-adenine coordination polymer.

Multifunctional coordination polymers based on copper with modified nucleobases, easily modulated in size and conductivity

“…In addition, nanoprocessability of these CP materials (nano coordination polymers (NCPs)) is required, in order to incorporate them at the biological level. In this regard, there is already a considerable number of studies that take advantage of the great insolubility of the CPs to form them at the nanoscale, based on bottom-up strategies, using either rapid precipitation in poor solvents [9] or in the presence of surfactants among other alternatives [10,11]. There are also works that describe how to prepare these materials at the nanosize scale using top-down approaches.…”

Reusable and pH-Stable Luminescent Sensors for Highly Selective Detection of Phosphate

“…The strong coordination interaction between europium and phosphate in the CPP is considered to provide exceptional selectivity and sensitivity as well as stability in various pH ( Figure 1 a). The CPP in this study is more durable in the aquatic environment than common luminescent metal-organic frameworks and can be synthesized in the form of nanoparticles that can be easily embedded into the porous membrane [ 25 , 26 ]. The resulting luminescent membrane containing the CPP is expected to be installed in a probe-type photoluminescent sensor adapted for the commercial dissolved-oxygen sensor as shown in Figure 1 b [ 27 ].…”

Immobilization of Air-Stable Copper Nanoparticles on Graphene Oxide Flexible Hybrid Films for Smart Clothes

“…Equipment employed in the gas phase method is expensive and difficult to operate; particles obtained by the solid phase method have rough surfaces and uneven particle size distributions. In comparison, the liquid phase method has low equipment requirements, allows easy control of particle size, and a high production efficiency, which have led to its wide applications in research [27,28]. For CuNPs, the smaller particle size leads to a higher surface activity and a greater probability of agglomeration and air oxidation [29].…”
