Ngophuhliso lwe-biotechnology kunye neteknoloji ye-peptide synthesis, imathiriyeli ye-Optoelectronic ye-Organic luhlobo lwemathiriyeli ephilayo enemisebenzi ye-photoelectric, esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana ne-light-emitting diodes (ii-LED, njengoko kubonisiwe kuMfanekiso 1), i-organic transistors. , iiseli zelanga eziphilayo, imemori ephilayo, njl njl. Izinto ze-Optoelectronic ze-Organic zidla ngokuba zii-athom ze-carbon ezityebileyo kwaye zinenkqubo enkulu ye-π-conjugated.Zinokwahlulwa zibe ziindidi ezimbini, kubandakanywa iimolekyuli ezincinci kunye neepolymers.Xa kuthelekiswa nezixhobo ze-inorganic, i-organic optoelectronic materials inokufezekisa ukulungiswa kwendawo enkulu kunye nokulungiswa kwesixhobo esiguquguqukayo ngendlela yesisombululo.Ngaphaya koko, izixhobo ze-organic zinezinto ezahlukeneyo zolwakhiwo kunye nendawo ebanzi yolawulo lokusebenza, ezenza zilungele uyilo lwemolekyuli ukufezekisa umsebenzi ofunekayo kunye nokulungiselela izixhobo ze-nano okanye iimolekyuli ngeendlela zokudityaniswa kwesixhobo esisezantsi ukuya phezulu, kubandakanya ukuzihlanganisa. indlela.Ke ngoko, izixhobo ze-organic optoelectronic zifumana ingqwalasela engakumbi nangakumbi kubaphandi ngenxa yeenzuzo zayo zendalo.
Umzobo 1. Uhlobo lwezinto eziphilayo zepolymer ezinokuthi zisetyenziswe ukulungisa ii-LEDs.Iveliswe kwakhona kwireferensi 1.
Umzobo 2. Ifoto yomatshini weSepaBean™, isistim elungiselela ulwelo lwechromatography.
Ukuqinisekisa ukusebenza okungcono kwinqanaba elilandelayo, kuyimfuneko ukuphucula ukucoceka kwekhompawundi ekujoliswe kuyo kangangoko kunokwenzeka kwinqanaba lokuqala lokudibanisa izinto ze-organic optoelectronic.Umatshini we-SepaBean™, isixokelelwano esilungiselelwayo se-flash solwelo lwechromatography eveliswe yi-Santai Technologies, Inc. inokwenza imisebenzi yokwahlula kwinqanaba ukusuka kwii-milligrams ukuya kumakhulu eegram.Xa kuthelekiswa ne-chromatography ye-manual manual kunye neentsika zeglasi, indlela ezenzekelayo inokulondoloza kakhulu ixesha kunye nokunciphisa ukusetyenziswa kwe-solvents ye-organic, inika isisombululo esisebenzayo, esikhawulezayo kunye nesoqoqosho sokwahlula kunye nokucocwa kweemveliso zokwenziwa kwezinto ze-organic optoelectronic.
iCandelo loMfuniselo
Kwinqaku lesicelo, i-organic optoelectronic synthesis eqhelekileyo yaqeshwa njengomzekelo kwaye iimveliso ezikrwada zokusabela zahlulwa kwaye zahlanjululwa.Imveliso ekujoliswe kuyo yahlanjululwa ngexesha elifutshane kakhulu ngumatshini we-SepaBean™ (njengoko kubonisiwe kuMfanekiso 2), yenza mfutshane kakhulu inkqubo yovavanyo.
Isampuli yayiyimveliso yokwenziwa kwezinto eziqhelekileyo ze-optoelectronic.Indlela yokusabela iboniswe kuMfanekiso 3.
Umzobo 3. Ifomula yokusabela yohlobo lwezinto eziphilayo ze-optoelectronic.
Itheyibhile 1. Ukuseta umfuniselo wolungiselelo lweflash.
Iziphumo neengxoxo
Umzobo 4. Ikhromatogram ekhanyayo yesampulu.
Kwinkqubo yokucoca i-flash preparative, i-40g ye-SepaFlash Standard Series ye-silica cartridge isetyenzisiwe kwaye uvavanyo lokucoca luqhutywe malunga ne-18 column volumes (CV).Imveliso ekujoliswe kuyo yaqokelelwa ngokuzenzekelayo kwaye i-flash chromatogram yesampuli iboniswe kuMzobo 4. Ukufumanisa nge-TLC, ukungcola ngaphambi nangemva kwendawo ekujoliswe kuyo kunokwahlulwa ngokufanelekileyo.Uvavanyo lulonke lokucoca olulungiselelwayo lwe-flash luthathe iyonke malunga nemizuzu engama-20, enokonga malunga ne-70% yexesha xa kuthelekiswa nendlela yekromatografi yesandla.Ngaphezu koko, ukusetyenziswa kwe-solvent ngendlela ezenzekelayo kwakumalunga ne-800 mL, ukonga malunga ne-60% ye-solvents xa kuthelekiswa nendlela yezandla.Iziphumo zokuthelekisa iindlela ezimbini ziboniswe kuMfanekiso 5.
Umzobo 5. Iziphumo zokuthelekisa iindlela ezimbini.
Njengoko kubonisiwe kweli nqaku lesicelo, ukuqeshwa komatshini weSepaBean™ kuphando lwemathiriyeli ye-organic optoelectronic inokonga ngokufanelekileyo izinyibilikisi ezininzi kunye nexesha, ngaloo ndlela ikhawulezisa inkqubo yovavanyo.Ngaphaya koko, idetector enovakalelo oluphezulu enokubonwa koluhlu olubanzi (200 - 800 nm) ixhotyiswe kwisistim inokuhlangabezana neemfuno zokubonwa kobude obubonakalayo.Ngaphaya koko, ingcebiso yendlela yokwahlula, inqaku elakhelwe ngaphakathi le-software ye-SepaBean™, inokwenza umatshini ube lula kakhulu ukuwusebenzisa.Ekugqibeleni, imodyuli yepompo yomoya, imodyuli engagqibekanga kumatshini, inokunciphisa ukungcoliswa kwendalo ngama-solvents eziphilayo kwaye ngaloo ndlela ikhusele impilo kunye nokhuseleko lwabasebenzi basebhubhoratri.Ukuqukumbela, umatshini weSepaBean™ odityaniswe neekhatriji zokucoca zeSepaFlash unokuhlangabezana neemfuno zesicelo sabaphandi kwicandelo lemathiriyeli ye-organic optoelectronic.
