Diphenyl-1-pyrenylphosphine: photo-triggered AIE/ACQ transition with remarkable third-order nonlinear optical signal change

A propeller-like pyrene derivative of diphenyl-1-pyrenylphosphine (DPPP) is designed and synthesized. DPPP exhibits a unique photo-triggered AIE/ACQ transition with a remarkable third-order nonlinear optical signal change, which is proved to originate fro

Thermally populated "bright" states for wide-range and high temperature sensing in air

A series of air-stable triarylphosphine oxide-based thermosensitive ratiometric sensors based on local excited (LE) and charge transfer (CT) emissions have been designed and synthesized. The fluorescence intensity of tri(pyren-1-yl)phosphine oxide exhibit

Highly Cytotoxic Ruthenium(II)-Arene Complexes from Bulky 1-Pyrenylphosphane Ligands

In the present study, the potential anti-neoplastic properties of a series of ruthenium half-sandwich complexes of formula [Ru(η6-arene)Cl2(PR1R2(1-pyrenyl))] (η6-arene = p-cymene and R1 =

An improved synthetic method for diphenyl-1-pyrenylphosphine and the properties and structure of its borane adduct

An efficient synthetic method for diphenyl-1-pyrenylphosphine, DPPP, has been developed involving a low temperature Li-Br exchange reaction using the commercially available 1-bromopyrene. An estimate of the donor ability of this phosphine has been obtaine

Phosphorus-Directed Rhodium-Catalyzed C?H Arylation of 1-Pyrenylphosphines Selective at the K-Region

C?H arylation of 1-pyrenylphosphine derivatives catalyzed by rhodium and directed by a diphenylphosphino group is selectively achieved at the K-region, i. e. 4-, 5-, 9-, or 10-position of the pyrene moiety. This peri C?H activation/arylation of pyrenes us

Organic electroluminescent material and organic luminescent device thereof

The invention provides an organic electroluminescent material and an organic luminescent device thereof and belongs to the technical field of organic photoelectric materials. The organic electroluminescent material provided by the invention structurally contains a pyrene structure; and through connecting an aryl Si group, an aryl phosphine oxo group and an aryl sulfuryl group, a conjugate structure is effectively broken, and thus, a triplet energy level is higher. Meanwhile, the organic electroluminescent material provided by the invention structurally contains a powerful electron withdrawinggroup, so that the organic electroluminescent material has excellent electron transporting capability, can be applied to the organic luminescent device as a luminescent layer material or electron transport layer material and has higher luminescence efficiency and lower driving voltage.

PHOSPHINE COMPOUND, PROCESS FOR PRODUCING THE SAME, AND PEROXIDE SCAVENGER USING THE SAME

The invention provides a novel peroxide scavenger comprising a phosphine compound represented by general formula [I]: wherein Z1 and Z2 each represents a cyclic group; Ar represents an arylene group; R represents an aliphatic hydrocarbon group; Y represents phosphorus (P), nitrogen (N), or bismuth (Bi); and R1, R2, and R3 each represents a cyclic group, particularly a peroxide scavenger that can scavenge peroxides such as reactive oxygen species which are generated in mitochondria upon exposure to oxidative stress and localized in mitochondria. The phosphine compound of the invention is oxidized by the peroxides localized in mitochondria to increase the fluorescence intensity, whereby the peroxides can be scavenged.
