[0040] Indium-Based Metal-Organic Framework Encapsulated Functional Cation Ru(bpy) 3 2+ Fluorescent material In(BTB)(OA) 1 / 2 Ru 1 / 2 (bpy) 3 / 2 Synthesis

[0041] 0.08mmol hydrated indium nitrate In(NO 3 ) 3 .XH 2 O was dissolved in 6 mL of N,N-dimethylformamide (DMF), N,N-diethylformamide (DEF) and ethanol (EtOH) mixed solution (volume ratio 1:1:1), under slow stirring Add 0.010mmol 1,3,5-tris(4-carboxyphenyl)benzene (BTB), 0.15mmol oxalic acid (OA) and 0.0156mmol Ru(bpy) 3 2+ X, stir evenly at room temperature to obtain a mixed solution. The solution was transferred to a 20mL polytetrafluoroethylene reactor, heated at 130°C for 4 days, controlled at 10°C / min to room temperature, and red blocky crystals were obtained. The crystals were separated by filtration and air-dried under natural conditions to obtain the indium-based metal-organic framework-wrapped functional cation Ru(bpy) 3 2+ fluorescent material.

[0044] Indium-Based Metal-Organic Framework Encapsulated Functional Cation Ru(bpy) 3 2+ Fluorescent material In(BTB)(OA) 1 / 2 Ru 1 / 2 (bpy) 3 / 2 Synthesis

[0045] 0.08mmol hydrated indium nitrate In(NO 3 ) 3 .XH 2 O was dissolved in 6 mL of N,N-dimethylformamide (DMF), N,N-diethylformamide (DEF) and ethanol (EtOH) mixed solution (volume ratio 1:1:1), under slow stirring Add 0.010mmol 1,3,5-tris(4-carboxyphenyl)benzene (BTB), 0.15mmol oxalic acid (OA) and 0.0156mmol Ru(bpy) 3 2+ X, stir evenly at room temperature to obtain a mixed solution. The solution was transferred to a 20mL polytetrafluoroethylene reactor, heated at 130°C for 5 days, controlled at 10°C / min to room temperature, and red blocky crystals were obtained. The crystals were separated by filtration and air-dried under natural conditions to obtain the indium-based metal-organic framework-wrapped functional cation Ru(bpy) 3 2+ fluorescent material.

[0047] Indium-Based Metal-Organic Framework Encapsulated Functional Cation Ru(bpy) 3 2+ Fluorescent material In(BTB)(OA) 1 / 2 Ru 1 / 2 (bpy) 3 / 2 Synthesis

[0048] 0.08mmol hydrated indium nitrate In(NO 3 ) 3 .XH 2 O was dissolved in 3 mL of N,N-dimethylformamide (DMF), and 0.010 mmol of 1,3,5-tris(4-carboxyphenyl)benzene (BTB), 0.15 mmol of oxalic acid (OA) and 0.0156 mmol of Ru were added under slow stirring (bpy) 3 2+ X, stir evenly at room temperature to obtain a mixed solution. The solution was transferred to a 20mL polytetrafluoroethylene reactor, heated at 130°C for 3 days, controlled at 10°C / min to room temperature, and red blocky crystals were obtained. The crystals were separated by filtration and air-dried under natural conditions to obtain the indium-based metal-organic framework-wrapped functional cation Ru(bpy) 3 2+ fluorescent material.

Abstract

The invention belongs to the field of fluorescent materials and particularly relates to an indium-based metal organic framework wrapped functional positive ion Ru(bpy)32+ fluorescent material. The indium-based metal organic framework wrapped functional positive ion Ru(bpy)32+ fluorescent material is characterized in that the molecular formula of the fluorescent material is In(BTB)(OA)1 / 2Ru1 / 2(bpy)3 / 2, wherein BTB is 1,3,5-tri(4-carboxyl phenyl) benzene, OA is oxalic acid and byp is 2,2'-bipyridine. The indium-based metal organic framework wrapped functional positive ion Ru(bpy)32+ fluorescent material provided by the invention not only retains excellent properties of an indium-based metal organic framework, but also can change the fluorescent service life of the fluorescent material in an organic ligand framework, so that a purpose of prolonging the fluorescent service life of Ru(bpy)32+ to [mu]s level is achieved. The preparation method is simple in process and easy to operate.

Description

technical field [0001] The invention belongs to the field of fluorescent materials, in particular to an indium-based metal-organic framework wrapped functional cation Ru(bpy) 3 2+ fluorescent material. Background technique [0002] Metal-organic frameworks (MOFs) are porous solid-state materials composed of organic ligands and metal coordination compounds (molecular building blocks or MBBs). From the perspective of the components of metal-organic frameworks, the metal ions involved in the construction of metal-organic frameworks are no longer limited to commonly used transition metal ions (such as: Zn 2+ 、Cd 2+ 、Cu 2+ ) and rare earth ions, alkali metal ions (Li + 、Na + etc.), alkaline earth metal ions (Mg 2+ ) and some ions with special properties (such as: In 3+ , Zr 4+ ) and so on have joined the ranks of metal ions that can construct MOFs. The ligands for building metal-organic frameworks have developed from simple monodentate nitrogen-containing ligands to pol...
