Isingeniso
Ngokuthuthuka kwe-biotechnology kanye nobuchwepheshe be-peptide synthesis, izinto ze-Organic optoelectronic ziwuhlobo lwezinto eziphilayo ezinemisebenzi ye-photoelectric, ezisetshenziswa kakhulu emikhakheni ehlukahlukene efana nama-light-emitting diode (ama-LED, njengoba kukhonjisiwe kuMfanekiso 1), ama-organic transistors. , amaseli elanga ephilayo, inkumbulo ephilayo, njll. Izinto ze-Organic optoelectronic ngokuvamile ama-molecule emvelo anothe ngama-athomu ekhabhoni futhi anesistimu enkulu ehlanganisiwe engu-π.Zingahlukaniswa zibe izinhlobo ezimbili, okuhlanganisa ama-molecule amancane nama-polymers.Uma kuqhathaniswa nezinto ezingaphili, izinto ze-organic optoelectronic zingafinyelela ukulungiswa kwendawo enkulu kanye nokulungiswa kwedivayisi okuguquguqukayo ngendlela yesisombululo.Ngaphezu kwalokho, izinto eziphilayo zinezinhlobonhlobo zezakhi zesakhiwo nendawo ebanzi yokulawula ukusebenza, okuzenza zilungele ukwakheka kwamangqamuzana ukufeza ukusebenza okufunayo kanye nokulungiselela amadivaysi e-nano noma ama-molecular ngezindlela zokuhlanganisa idivayisi eziya phezulu eziya phezulu, okuhlanganisa ukuzihlanganisa. indlela.Ngakho-ke, izinto ze-organic optoelectronic zithola ukunakwa okwengeziwe okuvela kubacwaningi ngenxa yezinzuzo zayo ezingokwemvelo.
Umfanekiso 1. Uhlobo lwe-organic polymer material engase isetshenziselwe ukulungisa ama-LED .Ikhiqizwe kabusha kusukela kunkomba 1.
Umfanekiso 2. Isithombe somshini we-SepaBean™, isistimu ye-chromatography ewuketshezi elungiselela i-flash.
Ukuqinisekisa ukusebenza okungcono esigabeni sakamuva, kuyadingeka ukuthuthukisa ukuhlanzeka kwenhlanganisela ehlosiwe ngangokunokwenzeka esigabeni sokuqala sokuhlanganiswa kwezinto eziphilayo ze-optoelectronic.Umshini we-SepaBean™, isistimu ye-flash preparative liquid chromatography ekhiqizwa i-Santai Technologies, Inc. ingenza imisebenzi yokuhlukanisa ngezinga ukusuka kuma-milligrams ukuya kumakhulu amagremu.Uma kuqhathaniswa ne-chromatography yamanuwali yendabuko enekholomu yengilazi, indlela ezenzakalelayo ingonga kakhulu isikhathi kanye nokunciphisa ukusetshenziswa kwezinyibilikisi zemvelo, inikeze isixazululo esiphumelelayo, esisheshayo nesongayo sokuhlukaniswa nokuhlanza imikhiqizo yokwenziwa kwezinto ze-organic optoelectronic.
Isigaba Sokuhlola
Encwadini yesicelo, i-organic optoelectronic synthesis evamile yasetshenziswa njengesibonelo futhi imikhiqizo yokusabela oluhlaza yahlukaniswa futhi yahlanzwa.Umkhiqizo okuhlosiwe wahlanzwa ngesikhathi esifushane umshini we-SepaBean™ (njengoba kuboniswe kuMfanekiso 2), okwenza kube mfushane kakhulu inqubo yokuhlola.
Isampula bekungumkhiqizo wokwenziwa wento evamile ye-optoelectronic.Ifomula yokusabela iboniswe kuMfanekiso 3.
Umfanekiso 3. Ifomula yokusabela yohlobo lwe-organic optoelectronic material.
Ithebula 1. Ukusethwa kokuhlolwa kokulungiswa kwe-flash.
Imiphumela nengxoxo
Umfanekiso 4. I-flash chromatogram yesampula.
Enqubweni yokuhlanza elungiselela i-flash, kusetshenziswe i-silica cartridge engu-40g SepaFlash Standard Series futhi isilingo sokuhlanza saqhutshwa cishe ngamakholomu angu-18 (CV).Umkhiqizo okuhlosiwe waqoqwa ngokuzenzakalelayo futhi i-flash chromatogram yesampula yaboniswa kuMfanekiso 4. Uma kutholwa nge-TLC, ukungcola ngaphambi nangemuva kwephoyinti okuhlosiwe kungahlukaniswa ngokuphumelelayo.Lonke ucwaningo lokuhlanza olulungiselela ukukhanya kuthathe isamba semizuzu engaba ngu-20, engonga cishe u-70% wesikhathi uma kuqhathaniswa nendlela ye-chromatography eyenziwa ngesandla.Ngaphezu kwalokho, ukusetshenziswa kwe-solvent ngendlela ezenzakalelayo kwakucishe kube ngu-800 mL, konga cishe u-60% wezincibilikisi uma kuqhathaniswa nendlela yezandla.Imiphumela yokuqhathanisa yalezi zindlela ezimbili ikhonjiswe kuMfanekiso 5.
Umfanekiso 5. Imiphumela yokuqhathanisa yalezi zindlela ezimbili.
Njengoba kubonisiwe kuleli nothi lohlelo lokusebenza, ukuqashwa komshini we-SepaBean™ ocwaningweni lwezinto ezibonakalayo ze-optoelectronic kungasindisa ngempumelelo izincibilikisi eziningi nesikhathi, ngaleyo ndlela kusheshiswe inqubo yokuhlola.Ngaphezu kwalokho, umtshina ozwela kakhulu onebanga elibanzi (200 - 800 nm) ofakwe ohlelweni ungahlangabezana nezidingo zokutholwa kobude begagasi obubonakalayo.Ngaphezu kwalokho, umsebenzi wokuncoma indlela yokuhlukanisa, isici esakhelwe ngaphakathi sesofthiwe ye-SepaBean™, singenza umshini ube lula kakhulu ukuwusebenzisa.Ekugcineni, imojula yepompo yomoya, imojula ezenzakalelayo emshinini, inganciphisa ukungcoliswa kwemvelo yizincibilikisi eziphilayo futhi ngaleyo ndlela ivikele impilo nokuphepha kwezisebenzi zaselabhorethri.Sengiphetha, umshini we-SepaBean™ ohlanganiswe ne-SepaFlash purification cartridges ungahlangabezana nezidingo zohlelo lokusebenza zabacwaningi emkhakheni wezinto eziphilayo ze-optoelectronic.
