Metal-organic supramolecular nanoarchitectures by Ru(II) bis-(terpyridine)-bridged pillar[5]arene dimers with triphenylamine

Probing the serum albumin binding site of fenamates and photochemical protein labeling with a fluorescent dye

“…Integrating triphenylamine into a D–π-A fluorescence system can lead to not only an excellent TICT effect, but also promising photodynamic behaviors. 27 Upon irradiation, the generated singlet oxygen 1 O 2 is highly reactive to the dyes themselves and the targeted biological substances. 28 To evaluate the subsequent photochemical events, the TTPy –HSA solution was irradiated with LED green light (peaked at 490 nm, 5 W) for 2 min and 4 min, separately.…”

Regulation of the supramolecular self‐assembly process by the number of 1, 8‐naphthalimide groups in the gelator

“…Therefore, it is urgently needed to develop the effective regulation method of supramolecular self-assembly of gelator. In the past few years, self-assembly of monomers, [54] dimers, [55][56][57][58][59][60] trimmers [61,62] and gels [63] has been extensively investigated. In this work, three gelators NE1, NE2 and NE3 with different number of 1, 8naphthalimide groups were designed and synthesized based on the advantages of 1, 8-naphthalimide derivatives (Scheme 1).…”

Supramolecular aggregates constructed by pillar[5]arene-based host–guest interaction with aggregation-induced emission

“…15 Host-guest recognition, 16,17 being an extremely significant driving force in the construction of supramolecular polymers, is due to molecular recognition between receptor (host) and ligand (guest) molecules through noncovalent interactions. 18 The large host molecules usually have a hydrophobic or hydrophilic cavity for the inclusion of guest molecules, 19,20 where some organic molecules or their ions, metal ions, nanoparticles, or biomacromolecules, may be used as guests. 21 Since the concept of host-guest recognition is widely known, many macrocyclic host molecules, such as crown ethers, cucurbiturils, 22,23 cyclodextrins, 24 calixarenes, 25 and pillararenes 26,27 have been used as hosts to fabricate supramolecular polymers due to their excellent host-guest recognition abilities.…”
