Tunable aggregation-induced fluorescent and pressure-responsive luminescence supramolecular cages achieved by subcomponent self-assembly

A supramolecular assembly strategy towards organic luminescent materials

“…Therefore, it has a wide range of applications in catalysis, 1,2 artificial photosynthesis, 3,4 drug delivery, 5,6 detection 7,8 and other fields. In particular, when applied to the field of luminescence, different photophysical processes such as fluorescence, 9 room-temperature phosphorescence (RTP), 10,11 energy transfer 12 and electron transfer 13 processes can be regulated by supramolecular strategies, so that different luminescence and stimulus response (pH, 14 light, 15 temperature, 16 pressure, 17 etc. ) properties can be assigned to conventional dye units, which further portends the fabrication of new sensors.…”

Photocatalysis in Water-Soluble Supramolecular Metal Organic Complex

“…Similar to the nano-environments in natural systems, the hydrophobic cavities of water-soluble metal-organic cages (WSMOCs) with defined shapes and sizes provide internal spaces to isolate water for guest molecules, which can be selectively captured, isolated, and released to achieve control over chemical reactions [ 21 , 22 ]. WSMOCs are known to provide various bond geometries, orientations, and strengths and show excellent catalytic performance due to the diversity of ligands, mental centers, coordination sites, and configurations [ 23 , 24 , 25 ]. To date, the reported mediated reactions include the Diels-Alder reaction [ 26 , 27 , 28 ], Kemp elimination [ 29 , 30 ], Knoevenagel condensation [ 31 , 32 , 33 ], pericyclic reactions (e.g., [2 + 2]/[4 + 2] cycloaddition reactions) [ 34 , 35 , 36 ], etc., wherein most of these reactions were mediated by the tail-anchored functional group and/or the confined space for enhancing the local concentration and pre-organizing the substrates [ 37 , 38 , 39 ].…”

Luminescent covalent organic cages with a C3-symmetric structure for effective enantioseparation

“…These applications include sensing, 1,2 catalysis, [3][4][5] separation, 6,7 gas adsorption, [8][9][10] biological imitation, [11][12][13] and more. [14][15][16][17][18][19][20][21][22] Among the various architectures, threedimensional molecular cages have attracted significant interest for their exceptional structures, properties, and applications. Through coordinative self-assembly, researchers have successfully generated a diverse range of captivating skeletons, such as octahedrons, 23,24 tetrahedrons, [25][26][27][28] spirals, 29,30 capsules, 31,32 and others.…”
