Nrog rau txoj kev loj hlob ntawm biotechnology li zoo li peptide synthesis technology, Organic optoelectronic cov ntaub ntawv yog ib yam ntawm cov organic cov ntaub ntawv uas muaj photoelectric kev ua, uas yog dav siv nyob rau hauv ntau yam xws li lub teeb-emitting diodes (LEDs, raws li qhia nyob rau hauv daim duab 1), organic transistors. , organic solar cells, organic memory, etc. Organic optoelectronic cov ntaub ntawv feem ntau yog cov organic molecules nplua nuj nyob rau hauv carbon atoms thiab muaj ib tug loj π-conjugated system.Lawv tuaj yeem muab faib ua ob hom, suav nrog cov molecules me thiab polymers.Piv nrog rau cov ntaub ntawv inorganic, cov ntaub ntawv organic optoelectronic tuaj yeem ua tiav thaj chaw loj nrog rau kev npaj cov cuab yeej hloov tau yooj yim los ntawm txoj kev daws teeb meem.Tsis tas li ntawd, cov khoom siv organic muaj ntau yam khoom siv thiab qhov chaw dav rau kev tswj hwm kev ua haujlwm, uas ua rau lawv tsim nyog rau kev tsim qauv molecular kom ua tau raws li qhov xav tau thiab npaj cov khoom siv nano lossis cov khoom siv molecular los ntawm cov cuab yeej hauv qab-up, nrog rau kev sib dhos ntawm tus kheej. txoj kev.Yog li ntawd, cov ntaub ntawv organic optoelectronic tau txais kev saib xyuas ntau dua los ntawm cov kws tshawb fawb vim nws qhov txiaj ntsig zoo.
Daim duab 1. Ib hom khoom siv organic polymer uas tuaj yeem siv los npaj LEDs .Reproduced los ntawm kev siv 1.
Daim duab 2. Daim duab ntawm SepaBean™ tshuab, lub teeb nyem npaj kua chromatography system.
Txhawm rau kom muaj kev ua tau zoo dua nyob rau theem tom ntej, nws yog ib qho tsim nyog los txhim kho lub purity ntawm lub hom phiaj compound kom ntau li ntau tau nyob rau hauv lub sij hawm thaum ntxov ntawm synthesizing organic optoelectronic cov ntaub ntawv.SepaBean ™ tshuab, lub flash npaj ua kua chromatography system tsim los ntawm Santai Technologies, Inc. tuaj yeem ua cov haujlwm sib cais ntawm qib ntawm milligrams mus rau ntau pua grams.Piv nrog rau cov tsoos phau ntawv chromatography nrog iav kab, txoj kev tsis siv neeg tuaj yeem txuag lub sijhawm zoo nrog rau txo kev noj cov kuab tshuaj organic, muab cov kev daws teeb meem zoo, ceev thiab kev lag luam rau kev sib cais thiab kev huv ntawm cov khoom siv hluavtaws ntawm cov khoom siv optoelectronic.
Ntu kev sim
Hauv daim ntawv thov, ib qho kev sib xyaw ua ke ntawm cov organic optoelectronic tau ua haujlwm ua piv txwv thiab cov khoom siv tshuaj tiv thaiv tsis zoo raug cais tawm thiab huv.Cov khoom lag luam tau ua kom huv hauv lub sijhawm luv luv los ntawm SepaBean ™ tshuab (raws li qhia hauv daim duab 2), ua kom luv luv ntawm cov txheej txheem sim.
Cov qauv yog cov khoom hluavtaws ntawm cov khoom siv optoelectronic.Cov qauv tshuaj tiv thaiv tau pom hauv daim duab 3.
Daim duab 3. Cov tshuaj tiv thaiv mis ntawm ib hom organic optoelectronic khoom.

Cov txiaj ntsig thiab kev sib tham
Daim duab 4. Lub flash chromatogram ntawm tus qauv.
Nyob rau hauv cov txheej txheem purification flash, 40g SepaFlash Standard Series silica cartridge tau siv thiab qhov kev sim ua kom huv tau khiav mus txog li 18 kem ntim (CV).Lub hom phiaj cov khoom tau raug sau cia thiab flash chromatogram ntawm cov qauv tau pom nyob rau hauv daim duab 4. Tshawb xyuas los ntawm TLC, cov impurities ua ntej thiab tom qab lub hom phiaj taw tes tuaj yeem sib cais zoo.Tag nrho cov flash npaj ua kom huv si siv tag nrho li 20 feeb, uas tuaj yeem txuag tau li 70% ntawm lub sijhawm thaum muab piv nrog cov txheej txheem chromatography.Tsis tas li ntawd, qhov hnyav noj nyob rau hauv txoj kev tsis siv neeg yog kwv yees li 800 mL, txuag txog 60% ntawm cov kuab tshuaj thaum piv nrog phau ntawv qhia.Cov txiaj ntsig sib piv ntawm ob txoj hauv kev tau qhia hauv daim duab 5.
Daim duab 5. Cov txiaj ntsig sib piv ntawm ob txoj kev.
Raws li qhia hauv daim ntawv thov no, kev ua haujlwm ntawm SepaBean ™ tshuab hauv kev tshawb fawb ntawm cov khoom siv hluav taws xob cov khoom siv hluav taws xob tuaj yeem txuag tau ntau cov kuab tshuaj thiab lub sijhawm, yog li ua kom cov txheej txheem sim ua kom sai.Tsis tas li ntawd, lub ntsuas ntsuas siab heev nrog ntau yam kev kuaj pom (200 - 800 nm) nruab rau hauv lub kaw lus tuaj yeem ua tau raws li qhov yuav tsum tau ua kom pom lub teeb pom kev zoo.Ntxiv mus, txoj kev sib cais txoj kev pom zoo muaj nuj nqi, ib tug built-in feature ntawm SepaBean ™ software, yuav ua rau lub tshuab ntau yooj yim rau siv.Thaum kawg, lub tshuab nqus tsev twj tso kua mis, lub default module nyob rau hauv lub tshuab, tuaj yeem txo qhov kev sib kis ntawm ib puag ncig los ntawm cov kuab tshuaj organic thiab yog li tiv thaiv kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg ua haujlwm kuaj.Hauv kev xaus, SepaBean ™ tshuab ua ke nrog SepaFlash purification cartridges tuaj yeem ua tau raws li daim ntawv thov xav tau ntawm cov kws tshawb fawb hauv thaj chaw ntawm cov khoom siv hluav taws xob organic.
