Embodiment 1

[0080] According to the method of literature Chem.Eur.J.2007, 13, 1231-1239, the organometallic platinum (II) complex 4'-(4-dimethylaminophenyl)-2,2'; 6', 2"triple Pyridine platinum(II) chloride complex. Take 4'-(4-dimethylaminophenyl)-2,2'; 6',2"trippyridine platinum(II) chloride complex 30mg, ferrocene (purchased by Bailingwei Company, analytically pure) 13mg, dissolved in 4ml N,N-dimethylformamide (chromatographically pure), then add about 2ml triethylamine (analytically pure, after water removal treatment), and bubble with argon After 30 minutes, 5 mg of cuprous iodide (analytical pure) was added and ultrasonicated for 6 hours under an argon atmosphere. Then add 90 mg of potassium hexafluorophosphate (analytical grade), and continue ultrasonication for half an hour. Diethyl ether (analytical pure) was added thereto to obtain a brown precipitate, which was filtered by suction. The solid was repeatedly dissolved with acetonitrile (analytical grade), and diethyl ether (anal...

Embodiment 2

[0087] The organometallic platinum (II) complex NPtFc obtained in Example 1 was dissolved in an acetonitrile solution with analytical purity to obtain a saturated acetonitrile solution of the organometallic platinum (II) complex NPtFc. Preparation of one-dimensional micron or submicron materials by solution method: Take 2ml of the prepared NPtFc saturated acetonitrile solution and add it to a 10ml round bottom flask, then slowly add 4ml of analytically pure diethyl ether along the inner wall, statically at -25°C Set 6h, there is solid precipitation. Let the suspension stand in a centrifuge tube for 45 minutes, absorb the supernatant with a dropper, add ether to redisperse, drop it on a silicon chip and a copper grid, observe it with a scanning electron microscope and a transmission electron microscope, and the result is a One-dimensional microrods, the width and length of one-dimensional microrods are about 500nm-1.2μm and 30-100μm respectively (such as image 3 ).

[0090] Take 4'-(4-dimethylaminophenyl)-2,2'; 6',2" terpyridine chloride platinum (II) complex (synthesized according to literature, Chem.Eur.J.2007, 13, 1231 -1239.) 50mg, tetrathiafulvalenyl acetylene (synthesized according to literature method, Tetrahedron 2008, 64, 1345.) 24mg, dissolved in 6ml N, N-dimethylformamide (chromatographically pure), then add about 5ml of triethylamine (analytical pure, after water removal treatment), after bubbling with argon for 30min, add 5mg of cuprous iodide (analytical pure), ultrasonic 6h under argon atmosphere. Then add potassium hexafluorophosphate (analytical pure) 150mg, continue ultrasonication for half an hour. Add diethyl ether (analytical pure) therein to obtain black-brown precipitate, suction filtration. Solid dissolves repeatedly with acetonitrile, ether precipitation. Solid methanol (analytical pure) ultrasonic washing, suction filtration, obtain metal organoplatinum ( II) Complex NPtT 74 mg.

Abstract

The invention relates to a photo-conduction micron or submicron material, in particular to a one-dimensional micron or submicron material of metal organic platinum (II) coordination compounds, which can be used for manufacturing photo-conduction micron devices, and a preparation method of one-dimensional micron or submicron material of the metal organic platinum (II) compounds. The one-dimensional micron or submicron material of the metal organic platinum (II) compounds is formed by metal organic platinum (II) coordination compounds which are self-combined under intermolecular PtII-PtII interaction, ligand Pi-Pi interaction or C-H- and PtII interaction. The one-dimensional micron or submicron material which is formed by self-combination through a solution method has properties of a semiconductor, the electric conductivity of the material is obviously increased under illumination, and the photoconductive devices are novel in structure, are convenient for preparation, have high responsiveness, are stable and can be used repeatedly.

Description

technical field [0001] The present invention relates to a photoconductive micron or submicron material, in particular to a one-dimensional micron or submicron material of a metal-organic platinum (II) complex that can be fabricated into a photoconductive micron device, and a one-dimensional metallo-organic platinum (II) complex Preparation methods of micron or submicron materials. Background technique [0002] The phenomenon that light causes the conductance of semiconductor materials to change is called the photoconductive effect. When light is irradiated on a semiconductor material, the material absorbs the energy of photons, making the electrons in the non-conducting state change into electrons in the conducting state, causing the carrier concentration to increase, thus leading to an increase in the conductivity of the material. The semiconductor is in a dark state when there is no light, and the material has dark conductance at this time; it is in a bright state when th...
