Uses

Used in Research Applications:
PHPY2 is used as a research chemical for studying the effects of synthetic cathinones on the human body and brain. Its psychoactive properties make it a valuable tool for understanding the mechanisms of action and potential risks associated with this class of drugs.
Used in Controlled Substances Regulation:
Due to its potency and potential risks, PHPY2 is used as a controlled substance in some countries to regulate its use and distribution. This helps to prevent misuse and abuse of the drug, as well as protect public health and safety.
Note: It is important to emphasize that PHPY2 is not approved for human consumption and should only be used for research purposes under appropriate legal and ethical guidelines.

Molecular structure and antimicrobial activity of a luminescent dinuclear silver(I) complex of phenyl-bis(2-pyridyl)phosphine

Phenyl bis(2-pyridyl)phosphine [PhP(2-py)2] and its silver nitrate complex of formula [Ag2(μ-(PhP(2-py)2) 2(NO3)2] (1) were synthesized and characterized by elemental analysis, IR spectrosc

Towards rainbow photo/electro-luminescence in copper(i) complexes with the versatile bridged bis-pyridyl ancillary ligand

The synthesis and characterization of a family of copper(i) complexes bearing a bridged bis-pyridyl ancillary ligand is reported, highlighting how the bridge nature impacts the photo- A nd electro-luminescent behaviours within the family. In particular, the phosphonium bridge led to copper(i) complexes featuring good electrochemical stability and high ionic conductivity, as well as a stark blue-to-orange luminescence shift compared to the others. This resulted in high performance light-emitting electrochemical cells reaching stabilities of 10 mJ at ca. 40 cd m-2 that are one order of magnitude higher than those of the other complexes. Overall, this work sheds light onto the crucial role of the bridge nature of the bis-pyridyl ancillary ligand on the photophysical features, film forming and, in turn, on the final device performances.

High performance solution-processed green phosphorescent organic light-emitting diodes with high current efficiency and long-term stability

In this study, we design and synthesize a new host and two new highly efficient green-emitting heteroleptic Ir(iii) complexes. These new materials are based on an amide-bridged, trifluromethyl-substituted, phenylpyridine skeleton with a longer alkyl chain as the main ligand, and on a phosphine oxide containing symmetrical dipyridinylphosphinate and asymmetrical phenyl(pyridin-2-yl)phosphinate as ancillary ligands. Their thermal, photophysical, electrochemical, and electroluminescent (EL) properties are fully investigated. The solution-processed green devices were fabricated using bis[5-ethylhexyl-8-trifluoromethyl-5H-benzo(c)(1,5)naphthyridin-6-one](dipyridinylphosphinate)iridium(iii) as dopant, and (4′-(9H-carbazol-9-yl)-[1,1′-biphenyl]-4-yl)di-o-tolylphosphine oxide (m-CBPPO1) and TPBi as hosts. The optimized devices containing a symmetrical-type ancillary ligand show excellent EL performance with a maximum current efficiency (CEmax) of 68.72 cd A-1 and a maximum external quantum efficiency (EQEmax) of 20.82% without compromising the color purity. This is one of the best reported CEmax values with high EQE for solution-processed phosphorescent organic light-emitting diodes (PHOLEDs). To the best of our knowledge, this is the first report on green solution-processed PHOLEDs with EQE over 20% by using phosphine oxide functionalized symmetrical type ancillary ligand. Furthermore, these devices with symmetrical Ir(iii) complexes show better device stability than that of asymmetrical Ir(iii) complexes, which is attributed to the formation of undesirable isomers in asymmetrical complexes.

Role of the Bridging Group in Bis-Pyridyl Ligands: Enhancing Both the Photo- and Electroluminescent Features of Cationic (IPr)CuI Complexes

We report on the benefits of changing the bridging group X of bis-pyridyl ligands, that is, Py-X-Py where X is NH, CH2, C(CH3)2, or PPh, on the photo- and electroluminescent properties of a new family of luminescent cationic H-heterocyclic carbene (NHC) copper(I) complexes. A joint experimental and theoretical study demonstrates that the bridging group affects the molecular conformation from a planar-like structure (X is NH and CH2) to a boat-like structure (X is C(CH3)2 and PPh), leading to i) four-fold enhancement of the photoluminescence quantum yield (?em) without affecting the thermally activated delayed fluorescence mechanism, and ii) one order of magnitude reduction of the ionic conductivity (σ) of thin films. This leads to an overall enhancement of the device efficacy and luminance owing to the increased ?em and the use of low applied driving currents.

Nitrogenous heterocyclic phosphoric acid and preparation method thereof, and luminescent device using nitrogenous heterocyclic phosphoric acid

The invention relates to a compound with a nitrogenous heterocyclic phosphoric acid structure. The compound can be used as a metal ligand for preparation of an organic luminescent material. Compared with extensively researched and reported phosphoric acid ligand, the novel nitrogenous heterocyclic phosphoric acid ligand provided by the invention has the advantages of stable chemical properties, easiness in purification, etc. and can effectively regulate the luminescence color of a metal complex due to introduction of a heavy electron phosphoric acid coordination structure. Through modification of the molecular structure of substituent on a nitrogenous heterocyclic ring, the luminescence position of the complex can be adjusted in the range of blue light wavelength, which facilitates designing and production of organic electroluminescence displays and illumination light sources. Moreover, the invention provides a synthetic method for a series of novel nitrogenous heterocyclic phosphoric acids. The synthetic method is simple, has high yield and realizes flexible chemical modification of heterocycles.

Versatile and efficient synthesis of a new class of aza-based phosphinic amide ligands via unusual P-C cleavage

A new class of bidentate, aza-based phosphinic amide ligands of the type RN(H)P(=O)(2-py)2 (2-py=2-pyridyl) was synthesized within minutes via a one-pot process including Staudinger reaction of an organic azide (RN 3) with 2-pyridylphosphines, followed by partial, unprecedented hydrolysis under loss of one aromatic substituent. The structure of the unusual-hydrolysis product H2C=CH(CH2)9N(H)P(= O)(2-py)2 (5a) was characterized by IR, 1H- and 31P-NMR, as well as by X-ray crystal-structure analysis (Figure). The tetrahedral P-atom was found to be surrounded by a trigonal-pyramidal arrangement of the substituents. To gain insight into the formation of these novel phosphinic amides, a series of intermediate iminophosphoranes, H 2C=CH(CH2)9N=P(Ar)n(2-py) 3-n (n = 0-3), compounds 1a-1f, were synthesized, and their hydrolyses were studied. All tested compounds followed the classical hydrolysis route of P=N cleavage under acidic conditions. Sequential hydrolysis to 5a-5d only occurred under either basic conditions or in wet MeCN as solvent. Notably, H2C=CH(CH2)9N=P(C6H 5)(4-MeO-2-py)2 (1c) was hydrolyzed at a much slower rate compared to its analogue 1b lacking the MeO group. On the contrary, the halogenated compounds H2C=CH(CH2)9N=P(4-X- C6H4)3 (1f,g) (X = F, Cl) were hydrolyzed at a notably faster rate relative to the non-halogenated congener 1e (X = H).

Electrosynthesis of triorganylphosphines from organic halides and chlorophosphines, catalyzed by nickel complexes

The possibility of cross coupling of organic halides and chlorophosphines under the action of electrochemically generated Ni(0) complexes of 2,2′-bipy is shown. The final triorganylphosphines are formed by several pathways, including reaction of the σ complex of ArNiX with chlorophosphine and electron transfer-induced reductive elimination of Ph2PArNiX, leading to the cross-coupling product.
