Coordination polymer nanoparticles from nucleotide and lanthanide ions as a versatile platform for color-tunable luminescence and integrating Boolean logic operations

Abstract

Novel supramolecular coordination polymer nanoparticles (CPNs) were synthesized via the self-assembly of guanosine monophosphate (GMP) and lanthanide ions (Ln, including Tb, Eu and Ce) in aqueous solution. These CPNs (GMP/Tb, GMP/Eu and GMP/Ce) have an identical coordination environment but exhibit completely different luminescence properties responding to external stimuli such as dipicolinic acid (DPA), ethylene diamine tetraacetic acid (EDTA), pH and metal ions, which has inspired us to tune the emission color of the CPNs and perform multiple logic operations. Firstly, color-tunable luminescence from red to green can be easily achieved by modulating the doping ratio of Tb and Eu into GMP. Notably, trichromatic white light emitting CPNs can be successfully realized by simultaneously doping Tb, Eu and Ce into the host or just adjusting the pH of the solution. What's more, by employing GMP/Tb CPNs as a logic operator, we have achieved the implementation of multilayered gate cascades (INH-INH, NOR-OR). When GMP/Eu CPNs served as a logic operator, the logic elements can be integrated as another combinatorial gate (AND-INH). Moreover, by employing the red emission of Eu and blue emission of GMP as the dual-output signal transducer, a set of parallel logic gates was established successfully. These results help elucidate the design rules by which simple logic can be integrated to construct cascaded logic gates and expand the applications of CPNs in light-emitting diode (LED) lamps and biological systems.

“…28,29 Various applications of such CPs in loading guest molecules and sensing have been explored. 28−31 Under certain conditions, such materials can also form hydrogels. 32 By using other metal ions, such as Zn 2+ , 33 Fe 3+ , 34 Au 3+ , 35−37 and Cu 2+ , 38 coordination materials forming hydrogels, coating materials, and nanozymes have also been demonstrated.…”

Preparation of Phosphoric Acid-Functionalized SBA-15 and Its High Efficient Selective Adsorption Separation of Lanthanum Ions

“…Rare-earth elements have become an important strategic resource for traditional industries, high-tech industries, and defense and safety technology industries around the world. They are called “technical seeds” or “industrial vitamins.” Among them, lanthanum (La) is widely used in the production of superalloys, catalysts, batteries, and ceramics in pure form or in combination with other elements. , However, excessive consumption and development of rare-earth resources have led to a significant decline in rare-earth reserves. In addition, a large amount of rare-earth waste is left in the environment, causing serious environmental pollution.…”

An All‐in‐One Molecule for the One‐Step Synthesis of Functional Hybrid Silica Particles with Tunable Sizes

“…Antisolvent precipitation is an attractive technique for the elaboration of nanoparticles (NPs) and finds applications in various fields such as electro‐optics, catalysis, and nanomedicine, notably with the elaboration of imaging agents and for improving drug formulation. Alternatively, the design and synthesis of nanoscale metal–organic frameworks have provided tunable nanoobjects to serve as functional platforms . However, despite the size tunability of the resulting particles, their high interfacial area renders them prone to aggregation and Oswald ripening, which affect their stability .…”
