Responsive macrocyclic and supramolecular structures powered by platinum

“…The use of self-assembly allows for the construction of highly ordered and tunable materials with precise control over the size, shape, and composition of the resulting structures. 42 …”

Dual Emissive Mono- and Bis-alkynylpyridinium Pt(II) Complexes: Synthesis and Luminescent Properties

“…Alkynyl Pt(II) complexes with Nheterocyclic ligands N ∧ N/C ∧ N ∧ N represent an important class of these luminescent compounds demonstrating a wide range emission, which is tunable by varying both the N-ligand composition and the alkynyl substituent. 1−6 The emission properties of these Pt(II) complexes have been utilized in the development of functional supramolecular 7 and nanoscale architectures, 8 OLED devices, 3,9 stimuli responsive and switchable materials for molecular electronics, 10 materials for nonlinear optics, 11 sensors, 12 etc. Despite significant progress, this area of organometallic chemistry is still in the state of active development, and a new concept in the molecular design of Pt(II) complexes is the use of "D−π−A" molecules as ligands.…”

“…Yield: 0.023 g (76%), orange solid. 1 [Pt(ppbipy)C�C(C 6 H 4 )(C 5 H 4 N + CH 3 )](OTf) (7). A 25 mL Schlenk flask was charged with 0.030 g (0.056 mmol) of [Pt(ppbipy)Cl], 0.005 g of CuI (0.026 mmol), 10 mL of distilled DMF, and 3 mL of diisopropylamine and vigorously purged with argon, and then 0.038 g (0.111 mmol) of N-methyl-4-(4-ethynylphenyl-1-yl)pyridinium triflate was added, purged with argon, and stirred 48 h at room temperature.…”

A Series of Planar Phosphorescent Cyclometalated Platinum(II) Complexes as New Anticancer Theranostic Agents That Induce Oncosis

“…Theoretically, square-planar cyclometalated platinum­(II) diimine complexes allow the formation of stacked forms caused by intermolecular noncovalent Pt–Pt interactions and π–π interaction induced by diimine ligands with small steric hindrance, , which may exhibit various phosphorescence properties. However, few studies have reported how platinum­(II) complexes of a diimine ligand with weak or strong steric hindrance combine or react with various biomolecules in living cells and the optical changes induced by variation in the external environment. , In addition, biomolecular targets and the specific anticancer mechanism of these compounds are basically unknown.…”

“…However, cyclometalated platinum(II) diimine complexes barely show any significant luminescence under room-temperature conditions, which greatly hinder their further application in bioimaging and sensing. 19 Theoretically, square-planar cyclometalated platinum(II) diimine complexes allow the formation of stacked forms caused by intermolecular noncovalent Pt−Pt interactions and π−π interaction induced by diimine ligands with small steric hindrance, 20,21 which may exhibit various phosphorescence properties. However, few studies have reported how platinum-(II) complexes of a diimine ligand with weak or strong steric hindrance combine or react with various biomolecules in living cells 22 and the optical changes induced by variation in the external environment.…”
