Example Embodiment

[0043] Example 1:

[0044] See figure 1 with figure 2 As shown, the present embodiment provides a method for preparing a porphyrin covalently linked a nonlinear nanochemical material:

[0045] first step:

[0046] Add 1.3G dry MOS in 50ml Schlenk Bottles 2 In n 210mL of n-butyllithium was added at ambient. After sonication 2h, stirred for 2 days. After standing for 30min, the supernatant was removed, after addition of 20mL of ultrapure water residue was quenched with n-butyllithium. With an equal volume of ethanol, the ultrasonic 30min. Centrifuge at 12000rpm was centrifuged 20min, the precipitate was collected. The resulting pellet was re-dispensed into ethanol, the above operation is repeated to wash organics. The precipitate was dispersed in ultrapure water, to remove MoS unpeeled was centrifuged at 4000rpm 30min 2 . The supernatant was centrifuged at 12000rpm at high speed 20min, the precipitate was collected. The precipitate was redispersed in ultrapure water, centrifuged at ...

Abstract

The invention relates to a porphyrin covalently linked molybdenum disulfide nonlinear nano hybrid material as well as preparation and application of the porphyrin covalently linked molybdenum disulfide nonlinear nano hybrid material, zinc porphyrin is axially coordinated to the surface of layered molybdenum disulfide, and the nonlinear performance of an organic-inorganic hybrid material is enhanced through energy transmission between porphyrin and molybdenum disulfide. The preparation method comprises the following steps: stripping molybdenum disulfide into few layers through butyl lithium, covalently connecting p-aminopyridine to the surface of layered molybdenum disulfide through diazonium salt reaction, and connecting porphyrin with metal zinc coordinated at the center to the surface of p-aminopyridine modified molybdenum disulfide through axial coordination to obtain the porphyrin-molybdenum disulfide hybrid material. The covalent linkage enhances energy transmission between molybdenum disulfide and porphyrin, so that the hybrid material shows enhanced nonlinear optical performance under nanosecond 532 nm.

Description

Technical field [0001] The present invention belongs to the technical field of organic-inorganic function composites, involving a covalent linked molymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymolymantnamide and its preparation and application thereof. Background technique [0002] Diulfonated molybdenum serves as a transition metal disulfide, and has an interlayer structure of S-Mo-S. Diamolybdenum layer is connected by a chemical bond intensity, while the interlayer is only connected by Van Dew Huardi, so that bossol-shaped molybdenum sulfide peeling into an uniform or even single layer is achievable. Due to the quantum defined effect, the band gap thereof also changes as the number of molybdenum sulphide layers changes. Liquid phase stripping disulfide is a relatively convenient method, but the sulfide sulfide nanofilator after peeling is very easy to reconnect. Moistorombcombum hydride can be modified wi...
