Recent advances in the development of europium(iii) and terbium(iii)-based luminescent supramolecular metallogels

Abstract

In the recent past, special focus has been paid to the development of metallogels as novel luminescent materials from rationally designed gelators with lanthanide ions, especially europium (Eu(III)) and terbium...

Recent Advances in Stimuli‐Responsive Luminescent Supramolecular Lanthanide‐Based Metallogels

“…This causes Ln(III) emission spectra to be narrow and line‐like when excited by electromagnetic radiation. Nonetheless, it is crucial to note that the f‐f transitions are formally Laporte forbidden and only contribute to weak absorption extinction coefficients, leading to a feeble luminescence intensity for such systems [4,95–97] . Tackling this issue requires effectively populating the lanthanide excited state using sensitising chromophores, known as ‘Antennae’, which have a powerful light‐absorbing ability.…”

Stimuli-responsive and self-healing supramolecular Zn(ii)–guanosine metal–organic gel for Schottky barrier diode application

“…1 Low molecular mass organic compounds that self-assemble into ordered fibrillar morphology aided by non-covalent interactions such as coordination interactions, H-bonding, pi-pi stacking, etc., and can trap solvent molecules form the basis of supramolecular gels. [2][3][4][5][6][7] Likewise metal-organic gels, which are a sub-class of supramolecular gels, result from the interaction of low molecular mass organic ligands with specific metal ions, followed by selfassembly under the influence of coordination interactions. [8][9][10][11][12] The formation of supramolecular metal-organic gels is an attempt to combine the properties of both the metal and organic counterparts in a single system with the aim of having better control over its morphology and properties.…”

Synthesis, structure and stimulus-responsive properties of a metallogel of a designer ferrocene appended peptide mimetic

“…34 Stimulus-responsive gels are vital for diverse applications, including sensors, imaging probes, semiconducting devices and storage devices. [35][36][37][38][39] Hence, the understanding of molecular self-assembly and gelation propensities is highly important.…”
