Tunable emission in lanthanide coordination polymer gels based on a rationally designed blue emissive gelator

Abstract

A new blue emissive gelator has been synthesized and its self-assembly with TbIII and EuIII results in coordination polymer gels, which show tunable emission based on stoichiometric control over LMWG:TbIII:EuIII.

Metal‐Organic Gel‐Derived Co/CoO/Co3O4 Composite for the Electrochemical Detection of Diethylstilbestrol

“…Metal‐organic gel (MOG) is also called the coordination polymer gel, which is assembled by gelator to form gel network structure, and the metal‐ligand coordination bond, hydrogen bond, π‐π stacking, and van der Waals force are the mainly interaction manners . MOG materials have been broadly applied in the drug carrier, sensor, catalysis and luminescence field owning to the properties of good compatibility, stimuli‐responses, high surface areas, inherently present open metal sites and large channels . Moreover, the abundant exposed metal sites of MOG could as potential active center and easy accessibility to detect target, and it is possible to directly employ MOG as electrode material for the electrochemical analysis and detection .…”

Mesoscale Assembly of Bisteroidal Esters from Terephthalic Acid

“…Recently, there has been an increased interest in the construction and design of new nano-architectural objects with well-defined shapes (nanoribbons [11], nanofibers [12], nanobelts [13], tubes [14], and rods [15]), in well-ordered and predictable sizes. Generally, a straight and efficient method for building these well-organized nanostructures is the control of supramolecular self-assembly by slightly altering environmental conditions, including solvent composition [16,17], temperature [18], pH changes [19,20], metal coordination [21], and light irradiation [22,23]. Consequent to their distinctive shapes, these nanostructures have shown potential applications, such as nanomaterials, supports for selective-catalysis, or templates to produce one-dimensional nanostructures [24].…”

Syntheses and topological structures of four luminescent lanthanide phosphonates based on 2-(pyridyl-N-oxide)methylphosphonic acid and oxalic acid

“…Moreover, lanthanide complexes usually exhibit unique optical properties, specifically large Stokes' shifts, high color purity, and relatively long luminescent lifetimes originating from f-f transitions through the ''antenna effect" [13]. Consequently, these complexes have been used in various lighting and light conversion applications, particularly lamp phosphors, light-emitting diodes, and medical imaging systems [14,15]. The phosphonate derivatives, especially those containing aromatics can act as the ''antennae" to sensitize the emission state of the lanthanide centers, which has led to most interesting developments in the coordination chemistry of lanthanide phosphonates.…”
