The Monolayers Are Composed Of Both An Electroactive Thiol,Hs(Ch2)(N)C(O)Nhch(2)Pyru(Nh3)(5)(2+/3+),With 10-15 Methylene Groups,And A Diluent Thiol,Hs(Ch2)Mcooh,Also With 10-15 Methylene Groups. The Monolayers Are Classified As ''Matched'' (N = M),''Exposed'' (N = 15,M = 10-14),And ''Buried'' (N = 10,M = 11-15) According To The Relative Position Of The Redox Center. Cyclic Voltammograms In Aqueous Na2So4 Indicate That The Monolayers Are Close-Packed With The Redox Centers Residing In The Aqueous Phase In All But The Most Buried Cases. Measurements Of Electron Transfer Kinetics By Several Methods (Cyclic Voltammetry,Ac Impedance Spectroscopy,Chronoamperometry) Yield An Internally Consistent Set Of Kinetic Parameters,The Standard Rate Constant K Degrees,And The Reorganization Energy Lambda Of The Redox Centers. The Reorganization Energies Are In Good Agreement With The Theoretically Predicted Value Of 1.0 Ev For The Pyru(Nh3)(5) Redox Centers. Plots Of Ln(K Degrees) Vs M Are Linear In All Three Cases. The Slopes Of The Linear Regression Fit Provide Tunneling Parameters (Beta,Where K Degrees Approximate To E(-Beta M)) Of 0.97 +/-0.03 (Matched Cases),0.83 +/-0.03 (Exposed Cases) And 0.16 +/-0.02 (Buried Cases) Per Methylene. This Pattern Of Beta'S Is Interpreted In Terms Of Electronic Coupling Between The Redox Center And The Electrode Via Both The Redox Thiol And The Proximate Diluent Thiols,With The Coupling Via The Diluent Thiols Dominating In The Exposed Cases.

专利号:US-2024352312-A1 优先权日:2021-06-25 标题:Microemulsion template assisted synthesis of cadmium-free near-infrared quantum dots based on i-iii-vi ternary semiconductors 发明人:WANG JUN 权利人:QUANTUM TECH GROUP 摘要:A method for making ternary core-shell semiconductor nanoparticles includes providing an emulsion including droplets dispersed in a continuous phase of a non-polar solvent. The droplets include a solution of ions of a Group I element and ions of a Group III element in a polar solvent, and are encapsulated by an interfacially active material. The emulsion is exposed to ions of a Group VI element to cause a reaction, thereby forming nanoparticles in the droplets. The nanoparticles in the droplets are with a first precursor to grow a shell on the nanoparticles, thereby forming core-shell nanoparticles. The core-shell nanoparticles are extracted from the emulsion; thermally annealed; and reacted with a second precursor to further grow the shell on the nanoparticles, thereby forming ternary core-shell semiconductor nanoparticles.
专利号:US-2025143061-A1 优先权日:2023-09-13 标题 :Molecular diode utilizing the characteristic of inducing electrically inactive organic molecules into molecules with electrical properties 发明人:YOON HYO JAE; KONG GYUDON 权利人:UNIV KOREA RES & BUS FOUND 摘要:Disclosed is a molecular diode using the assignment of electrical properties to inactive organic molecules when a self-assembled monolayer (SAM) thin film including an electrically inactive organic molecule is formed without synthesizing a separate organic molecule having electrical activity. The disadvantage of the instability of a conventional SAM can be overcome, a function can be extended, and electrical properties, such as a rectification characteristic in a non-functional molecule, can be induced even without the design and synthesis of organic molecules for introducing a functional molecule. Accordingly, the embodiments of the present disclosure can be usefully used in various technical fields in which an SAM is used, in particular, wide fields such as electronics, an organic display (OLED), solar cells, sensors, non-uniform catalysts, frictional electricity, cell growth surfaces, and a heat transfer control film.
