Ukuqalisa
Ngokuthuthukiswa kwe-biotechnology kanye nobuchwepheshe be-peptide synthetisos, izinto ze-organic opoleelectronic ziwuhlobo lwezinto eziphilayo ezinemikhakha enezinto ezibonakalayo ezinjengezinto ezibonakalayo ezinjengezinto ezibonakalayo ezifana nama-molecule ajwayelekile agcwele ikhabhoni ama-athomu nokuba nohlelo olukhulu lwe-π-conjugaged. Babengafakwa ezinhlotsheni ezimbili, kufaka phakathi ama-molecule amancane nama-polymers. Uma kuqhathaniswa nezinto zokwakha i-inorganic, izinto ze-organic optoelectronic zingafinyelela ukulungiswa kwendawo enkulu kanye nokulungiswa kwensiza okuguqukayo yindlela yesisombululo. Ngaphezu kwalokho, izinto eziphilayo zinezakhi ezahlukahlukene zesakhiwo kanye nendawo ebanzi yokulawulwa kokusebenza, okubenza balungele ukwakheka kwamangqamuzana ukufeza ukusebenza okufunayo kanye nokulungiselela izindlela ze-nano noma ze-molecular ngezindlela zokuzijabulisa. Ngakho-ke, izinto ze-Organic Optoelectronic zithola ukunakwa okwengeziwe nokuningi okuvela kubacwaningi ngenxa yezinzuzo zalo ezingokwemvelo.
Umdwebo 1. Uhlobo lwezinto eziphilayo ze-polymer ezingasetshenziswa ukulungiselela ama-LED.
Umdwebo 2
Ukuqinisekisa ukusebenza okungcono esiteji esizayo, kuyadingeka ukuthuthukisa ubumsulwa be-comfered compact ngangokunokwenzeka ekuqaleni kokuhlanganisa izinto eziphilayo ze-organic optoelectronic. Umshini we-Sepabean ™, uhlelo lwe-flash elungiselelwe i-chromatography uhlelo olukhiqizwa yiSantai Technologies, Inc. lungakwazi ukwenza imisebenzi yokuhlukanisa ezingeni elisuka kuma-milligrams kuya kumakhulu ama-gramu. Uma kuqhathaniswa ne-chromatography yendabuko yencwadzi ngekholomu yengilazi, indlela ezenzakalelayo ingasindisa kakhulu isikhathi futhi inciphise ukusetshenziswa kwezinto eziphilayo, okuvuthayo okusebenzayo, ukuhlanzwa kwemikhiqizo yokwenziwa kwezinto zokwenziwa ze-organic optoelectronic.
Isigaba Sokuhlola
Encwadini yesicelo, ukwakheka okujwayelekile kwe-opoleelectronic kwaqashwa njengesibonelo futhi imikhiqizo yokusabela engahluleki yahlukaniswa futhi yahlanzwa. Umkhiqizo oqondiwe wahlanzwa ngesikhathi esifushane ngomshini we-Sepabean ™ (njengoba kukhonjisiwe kuMfanekiso 2), kunciphisa kakhulu inqubo yokuhlola.
Isampula kwakuwumkhiqizo wokwenziwa wezinto ezijwayelekile ze-optoelectronic. Ifomula yokuphendula yaboniswa kuMfanekiso 3.
Umdwebo 3. Ifomula yokuphendula yohlobo lwezinto eziphilayo ze-optolectronic.
Ithebula 1. Ukusetha kokuhlola kokulungiswa kwe-flash.
Imiphumela nengxoxo
Umdwebo 4. I-flash chromatograph yesampula.
Enqubweni yokuhlanza okulungiselelwe nge-Flash, kwasetshenziswa i-sepaflash ejwayelekile ye-silica cartrid kanye nokuhlolwa kokuhlanzwa kwenziwa cishe amavolumu ayi-18 (CV). Umkhiqizo oqondiwe waqoqwa ngokuzenzakalela futhi i-flash chromatam yesampula yaboniswa kuMfanekiso 4. Ukutholwa yi-TLC, ukungcola ngaphambi nangemva kokuqondiwe kungahlukaniswa ngempumelelo. Ukuhlolwa kokuhlanza konke okulungiselelwa kwe-flash kwathatha ingqikithi yemizuzu engama-20, engagcina cishe ama-70% wesikhathi lapho kuqhathaniswa nendlela ye-Chromatography. Ngaphezu kwalokho, ukusetshenziswa kwe-solvent ngendlela ezenzakalelayo kwakucishe kube ngu-800 ml, ukonga cishe ama-60% ama-solvents uma uqhathanisa nendlela yezandla. Imiphumela yokuqhathanisa yalezi zindlela ezimbili yaboniswa kuMfanekiso 5.
Umdwebo 5. Imiphumela yokuqhathanisa yezindlela ezimbili.
Njengoba kukhonjisiwe kulolu hlelo lokusebenza Qaphela, ukuqashwa komshini we-Sepabean ™ ocwaningweni lwezinto eziphilayo ze-organic zingagcina kahle izixazululo eziningi nangesikhathi, ngaleyo ndlela sisheshise inqubo yokuhlola. Ngaphezu kwalokho, umtshina ozwela kakhulu ukutholwa okubanzi (200 - 800 NM) okuhlomele ohlelweni kungahlangabezana nezidingo zokutholwa kwe-wavelength ebonakalayo. Ngaphezu kwalokho, umsebenzi wokuncoma wendlela yokuhlukanisa, isici esakhelwe ngaphakathi sesoftware ye-Sepabean ™, ingenza umshini ube lula kakhulu ukusebenzisa. Ekugcineni, imodyuli yepompo yomoya, imodyuli ezenzakalelayo emshinini, inganciphisa ukungcoliswa kwemvelo yi-organic solvents futhi ngaleyo ndlela ivikele ezempilo kanye nokuphepha kwabasebenzi belebhu. Ekuphetheni, umshini we-Sepabean ™ uhlanganiswe nama-cartridgeges weSepaflash ahlanza angahlangabezana nezidingo zesicelo zabaphenyi emkhakheni wezinto zokwenziwa kwe-organic opoleelectronic.
