Embodiment 1

[0032] Embodiment 1[Cu(POP)(ptpm)]BF 4 The preparation method of copper complex:

[0033] a. Synthesize amino-o-phenanthroline and p-formyltriphenylamine according to the literature method, dissolve the two compounds in the same amount of substances in methanol, reflux for three hours, and cool to room temperature. A large amount of yellow crystals are precipitated, and they are filtered under reduced pressure. A yellow solid was obtained, recrystallized from chloroform methanol, separated by column chromatography (petroleum ether: ethyl acetate = 1:1), and dried in vacuo to obtain the bidentate ligand ptpm, Anal. Calcd for C 31 h 22 N 4 C82.64, H4.92, N12.44. Found: C82.34, H4.90, N12.46; 1 H NMR (CDCl 3 ,400M):d9.15(t,3H),8.12(s,H),7.74(m,2H),7.60(d,2H),7.34-7.15(m,14H).

Embodiment 2

[0036] Embodiment 2: the synthesis of I / MCM-41 (mass ratio 1:100)

[0037] Weigh 1 mg of khaki I and dissolve it in 9 ml of chloroform to form a dark yellow transparent solution, then add 100 mg of white MCM-41 from which the surfactant has been removed, stir for 1 hour and let stand for 30 minutes, then filter the solution. Washed 3 times with chloroform, air-dried at room temperature to obtain slightly yellow assembly I / MCM-41, the mass ratio of the compound to the carrier was 1:100.

Embodiment 3

[0038] Embodiment 3: the synthesis of I / MCM-41 (mass ratio 2:100)

[0039] Weigh 2 mg of khaki I and dissolve it in 9 ml of chloroform to form a dark yellow transparent solution, then add 100 mg of white MCM-41 from which the surfactant has been removed, stir for 1 hour and let stand for 30 minutes, then filter the solution. Washed 3 times with chloroform, air-dried at room temperature to obtain slightly yellow assembly I / MCM-41, the mass ratio of the compound to the carrier was 2:100.

Abstract

The invention discloses a composite luminescent material as well as application thereof on oxygen sensing aspect. A copper complex has an expression formula of [Cu(POP)(ptpm)]BF4 and has a chemical structural formula which is shown in the specification; the composite luminescent material is formed by loading the copper complex formed by a phenanthroline derivative and metal copper ions into an inorganic mesoporous molecular sieve duct. The copper complex emits green-yellow light under a 365nm ultraviolet lamp, has maximal emission peak near 510nm, is cheap in price, smaller in toxicity and easier to prepare. Moreover, the copper complex / composite luminescent material disclosed by the invention has emission intensity sensitive to oxygen gas concentration, and is an economical, green and environment oxygen sensing material.

Description

technical field [0001] The invention relates to a composite luminescent material and its application in oxygen sensing, in particular to a composite luminescent material formed by loading a copper complex formed by o-phenanthroline derivatives and metal copper ions into the channels of inorganic mesoporous molecular sieves. material, and the application of this material in oxygen sensor. Background technique [0002] Oxygen is one of the most abundant elements on the earth, and it is also an indispensable element to maintain life activities, and is closely related to production and life, so it is extremely necessary to control and master the amount of oxygen in real time. In order to meet the actual needs of industrial and agricultural production, environmental monitoring, especially chemical and chemical industries, it is of great significance to develop oxygen sensors suitable for different conditions. [0003] There are many types of oxygen sensors due to different worki...
