Ndi chitukuko cha biotechnology komanso ukadaulo wa peptide synthesis, Organic optoelectronic materials ndi mtundu wa zida za organic zomwe zimakhala ndi zinthu zamagetsi, zomwe zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga ma diode otulutsa kuwala (ma LED, monga momwe tawonetsera pa Chithunzi 1), organic transistors. , ma cell a solar organic, organic memory, etc. Organic optoelectronic materials nthawi zambiri amakhala mamolekyu okhala ndi ma atomu a carbon ndipo amakhala ndi dongosolo lalikulu la π-conjugated.Atha kugawidwa m'mitundu iwiri, kuphatikiza mamolekyu ang'onoang'ono ndi ma polima.Poyerekeza ndi zinthu zakuthupi, organic optoelectronic zida zimatha kukwaniritsa kukonzekera kwadera lalikulu komanso kukonza zida zosinthika ndi njira yothetsera.Kuphatikiza apo, zida za organic zimakhala ndi magawo osiyanasiyana ampangidwe komanso malo otakata owongolera magwiridwe antchito, zomwe zimawapangitsa kukhala oyenera kupanga mamolekyulu kuti akwaniritse zomwe akufuna komanso kukonza zida za nano kapena mamolekyulu pogwiritsa ntchito njira zolumikizira zida zapansi-mmwamba, kuphatikiza kudzipangira. njira.Chifukwa chake, zida za organic optoelectronic zimalandira chidwi chochulukirapo kuchokera kwa ofufuza chifukwa cha zabwino zake.
Chithunzi 1. Mtundu wa organic polima zinthu zomwe zingagwiritsidwe ntchito kukonza ma LED .Reproduced from reference 1.
Chithunzi 2. Chithunzi cha makina a SepaBean™, makina opangira ma chromatography amadzimadzi.
Kuti zitsimikizire kuti zimagwira bwino ntchito pambuyo pake, ndikofunikira kukonza chiyerekezo chazomwe mukufuna kuwongolera momwe mungathere kumayambiriro kwa kupanga zida za organic optoelectronic.SepaBean™ makina, flash preparative liquid chromatography system yopangidwa ndi Santai Technologies, Inc. imatha kugwira ntchito zolekanitsa pamlingo woyambira mamiligalamu mpaka mazana a magalamu.Poyerekeza ndi chromatography yachikhalidwe yokhala ndi mizati ya magalasi, njira yodziwikiratu imatha kupulumutsa nthawi komanso kuchepetsa kugwiritsa ntchito zosungunulira organic, kupereka njira yabwino, yofulumira komanso yotsika mtengo yolekanitsa ndi kuyeretsa zinthu zopangidwa ndi organic optoelectronic.
Gawo Loyesera
M'mawu ogwiritsira ntchito, organic optoelectronic synthesis wamba adagwiritsidwa ntchito monga chitsanzo ndipo zinthu zopanda pake zidalekanitsidwa ndikuyeretsedwa.Chogulitsidwacho chinayeretsedwa pakanthawi kochepa ndi makina a SepaBean™ (monga momwe tawonetsera pa Chithunzi 2), kufupikitsa kwambiri kuyesako.
Chitsanzocho chinali chopangidwa ndi chinthu chodziwika bwino cha optoelectronic.Njira yochitira ikuwonetsedwa pa chithunzi 3.
Chithunzi 3. Zomwe zimachitika pamtundu wa organic optoelectronic material.
Table 1. The experimental khwekhwe kukonzekera kung'anima.
Zotsatira ndi zokambirana
Chithunzi 4. Chromatogram yowala ya chitsanzo.
Munjira yoyeretsera kung'anima, katiriji ya silica ya 40g SepaFlash Standard Series idagwiritsidwa ntchito ndipo kuyesa koyeretsa kunayendetsedwa pafupifupi ma voliyumu 18 (CV).Chotsatiracho chinasonkhanitsidwa chokha ndipo flash chromatogram ya chitsanzo inasonyezedwa mu Chithunzi 4. Kuzindikira ndi TLC, zonyansa zisanayambe komanso pambuyo pa mfundo zomwe zikugwiritsidwa ntchito zingathe kulekanitsidwa bwino.Kuyesera konseko kokonzekera kuyeretsa kudatenga mphindi pafupifupi 20, zomwe zitha kupulumutsa pafupifupi 70% ya nthawiyo poyerekeza ndi njira yapamanja ya chromatography.Kuphatikiza apo, kugwiritsa ntchito zosungunulira mu njira yokhayo kunali pafupifupi 800 mL, kupulumutsa pafupifupi 60% ya zosungunulira poyerekeza ndi njira yamanja.Zotsatira zofananiza za njira ziwirizi zidawonetsedwa pazithunzi 5.
Chithunzi 5. Zotsatira zofananitsa za njira ziwirizi.
Monga momwe zasonyezedwera m'nkhaniyi, kugwiritsa ntchito makina a SepaBean™ pofufuza zinthu za organic optoelectronic kumatha kupulumutsa zosungunulira zambiri ndi nthawi, motero kufulumizitsa kuyesako.Kuphatikiza apo, chowunikira chodziwika bwino chomwe chili ndi mitundu yosiyanasiyana (200 - 800 nm) yokhala ndi makinawa imatha kukwaniritsa zofunikira pakuzindikira kutalika kwa mafunde.Kuphatikiza apo, ntchito yolimbikitsa njira zolekanitsa, zomwe zili mkati mwa pulogalamu ya SepaBean™, zitha kupangitsa makinawo kukhala osavuta kugwiritsa ntchito.Pomaliza, gawo la pampu ya mpweya, gawo losasinthika pamakina, limatha kuchepetsa kuipitsidwa kwa chilengedwe ndi zosungunulira za organic ndikuteteza thanzi ndi chitetezo cha ogwira ntchito za labotale.Pomaliza, makina a SepaBean™ ophatikizidwa ndi makatiriji oyeretsera a SepaFlash atha kukwaniritsa zomwe ofufuza apanga pankhani ya organic optoelectronic materials.
