Abstract
The chemiluminescent system comprising oxalate with asymmetric substituent as chemiluminescent material, fluorescent agent, oxidant, etc. has comprehensive luminescent property of oxalate with different substituent. The said system has high luminescent intensity long luminescent time and good stability.
Description
The present invention relates to a kind of chemical luminous system based on asymmetric barkite, fluorescent agent and oxygenant.
Chemiluminescent oxalate system is owing to have higher luminous efficiency, bigger luminous intensity and stability and obtain paying attention to and being applied to reality preferably, for example U.S. Pat 3749679, US4313843 and domestic disclosed patent CN1069051, CN1087109 etc., the barkite that is adopted in these patented technologies is symmetrical substituting group barkite, basic structure is R-O-(CO)-(CO)-O-R, and two substituent R are identical.This symmetrical substituting group barkite draws materials easily, synthetic simple, cost is lower, but luminescent properties has than big-difference, and is difficult to take into account the relation of luminous intensity and stability of photoluminescence, for example: two (2, the 4-dinitrophenol) (2,4-DNPO) luminous intensity with two (Pentachlorophenol) barkite (PCPO) is big, but stability is very poor for barkite, fluorescent lifetime is short, be difficult to make practical product, and two (2,4, the 6-trichlorophenol) barkite (TCPO) good stability, but light intensity a little less than.
It is big to the purpose of this invention is to provide a kind of not only luminous intensity, the long and good stability of fluorescent lifetime, economical and practical chemiluminescent oxalate system.
Chemical luminous system of the present invention is with barkite, fluorescent agent and oxygenant are to improve on the basis of main chemical luminous system to form, the present invention is characterized in that chemiluminescent substance used in this system is asymmetric substituting group barkite (hereinafter to be referred as an asymmetric barkite), basic structure is R1-O-(CO)-(CO)-O-R2, wherein R1 and R2 are two kinds of very big substituting groups of known performance difference, they can be Pentachlorophenol and 2,4,6-trichlorophenol or 2,4-dinitrophenol and 2,4,6-trichlorophenol or salicyclic acid derivatives etc. are with the synthetic asymmetric barkite of oxalyl chloride.In addition, the consumption of fluorescent agent and laying method have considerable influence to the stability of system, accurate metering for ease of fluorescent agent, guarantee system carries out photochemical reaction under the optimum concn ratio, can be with the benzole soln of fluorescent agent and the polystyrene molten polystyrene film that contains fluorescent agent of making altogether, this film one small pieces are joined in the middle of the above-mentioned asymmetric barkite powder.
In chemical luminous system of the present invention, the working concentration of asymmetric barkite is 0.01～0.1M, the concentration of fluorescent agent is 0.001M～0.01M, and the solvent of use is dimethyl phthalate (DMP) or dibutyl phthalate organic solvents such as (DBP), with hydrogen peroxide (H
2O
2) be 0.1～2M as its working concentration of oxygenant, and add a spot of sodium salicylate and stablizer.
Outstanding advantage of the present invention is the luminescent properties that combines different substituents oxalic acid vinegar, has taken into account luminous intensity and luminescent lifetime, by polystyrene fluorescent agent and barkite is isolated, and has improved the stability of product, makes its more economical practicality, is convenient to scale operation.
Embodiment:
The A component: (R1 is that Pentachlorophenol, R2 are 2,4 to asymmetric barkite 0.4g, polystyrene film one small pieces of 6-trichlorophenol) Han perylene fluorescent agent.
B component: the DMP solution 8ml of 0.5M hydrogen peroxide
Sodium salicylate 0.0001M
Stablizer 0.0001M
Effective fluorescent lifetime of body series than the long 1hr of simple PCPO system about, and the simple TCPO of luminous relative intensity ratio exceeds 2～3 times.
Claims (4)
1, a kind of is chemiluminescent substance with asymmetric substituting group barkite (hereinafter to be referred as asymmetric barkite), the polystyrene film that will contain fluorescent agent adds wherein, mixes with the solution of the organic solvent that is dissolved with oxygenant and manufactures a kind of asymmetric chemiluminescent oxalate system.
2, chemical luminous system according to claim 1, it is characterized in that asymmetric barkite basic structure is R1-O-(CO)-(CO)-O-R2, wherein R1 and R2 are two kinds of very big different substituents of known performance difference, they can be Pentachlorophenol and 2,4,6-trichlorophenol or 2,4-dinitrophenol and 2,4,6-trichlorophenol or salicyclic acid derivatives etc., the concentration of this asymmetric barkite is 0.01-0.1M.
3, chemical luminous system according to claim 1 is characterized in that the benzole soln of fluorescent agent and polystyrene is total to the molten polystyrene film that contains fluorescent agent of making, the working concentration scope 0.001～0.01M of fluorescent agent.
4, chemical luminous system according to claim 1 is characterized in that: join with hydrogen peroxide as oxidant in the organic solvents such as dimethyl phthalate, make its concentration reach 0.1～2M, and add a spot of sodium salicylate therein.
