Multicolor-tunable room-temperature afterglow and circularly polarized luminescence in chirality-induced coordination assemblies

Abstract

Dynamic long-lived multicolor room temperature afterglow and circularly polarized luminescence (CPL) are promising for optoelectronic applications, but these functions integrated into a single-phase chiroptical materials is still a difficult and...

Different anion (NO3− and OAc−)-controlled construction of dysprosium clusters with different shapes

“…Lanthanide clusters with nanometer size, beautiful structural connections, and diverse functions have attracted extensive attention [1][2][3][4][5] and have been successfully applied in solid-state luminescence, [6][7][8][9] sensing, [10][11][12][13][14] molecular magnetism, [15][16][17][18][19][20][21] and bioimaging. [22][23][24] So far, ligand-controlled hydrolysis and anion-templated methods are still the first choice for the synthesis of lanthanide clusters.…”

Chiral Coordination Assembly-Induced Phosphorescent Frameworks for Circularly Polarized Phosphorescence

“…Circularly polarized luminescence (CPL) has potential prospects in asymmetric synthesis, , chiral identification, , and optical encryption. , In recent years, various kinds of CPL-active materials have been designed and constructed, such as organic molecules, − supramolecular systems, , and polymers. − However, the current research is mainly focused on circularly polarized fluorescence materials; the number of circularly polarized phosphorescence (CPP) materials is relatively much smaller due to the instability of the triplet excited state and the difficulty in integration of chirality and phosphorescence. − …”

Recent advances in the design of afterglow materials: mechanisms, structural regulation strategies and applications

“…47–49 Organic–inorganic hybrid systems, an exciting new class of afterglow materials, possess adjustable structures and rich functionality. 50–52 They typically use metal ions as nodes and organic ligands as bridging groups, taking advantage of heavy atom effects involving the metal ions to accelerate the SOC of T 1 . 53 Furthermore, strong covalent bonding in organic-metal hybrids can stabilize the triplet energy of organic luminescent ligands to achieve a long afterglow emission.…”
