Ukwenziwa kahle kwe-pyrazolo [1,5-a] pyrimidine derivatives yezinto eziphilayo ze-optoelectronic kudinga ukulawulwa okuqinile kokuhlushwa kwe-reactant. Ukulinganiswa kobuningi obuphakathi kubalulekile ekugcineni ukuphindaphindeka kwe-batch-to-batch. Izimpawu zokuguquguquka kobuningi zithinta ubumsulwa, zithinta ngqo ukusebenza kwedivayisi ku-OLED kanye ne-photovoltaics eziphilayo. Izinqubo zezimboni zisebenzisa amamitha obuningi obuphakathi ukuqapha ukwakheka kwe-acetone dicarboxylic acid, isinyathelo esibalulekile esakha isakhiwo sendandatho ye-pyrazole esibalulekile kumadivayisi e-optoelectronic ephilayo.
Ukwenziwaof I-Pyrazolo [1,5-a] I-Pyrimidine Derivatives
Ukwenziwa kwe-pyrazolo [1,5-a] pyrimidine derivatives yezinto eziphilayo ze-optoelectronic kanye ne-organic photovoltaics kusebenzisa amasu okwenziwa kwe-organic stepwise. I-Acetone dicarboxylic acid isebenza njengesandulela esiyinhloko sokwakha isakhiwo sendandatho ye-pyrazole. Lesi sitshalo se-carboxylic acid sinikeza ukwakheka kwendandatho ekhiqiza kakhulu futhi sisekela ukwakheka kwe-batch okuthembekile ezinqubweni zezimboni.
Ukulawulwa okunembile kwezilinganiso zokudla kanye nokwakheka kwe-solvent kuthinta ngqo ukuhlanganiswa kwezingxenye eziphakathi kanye nokuphindaphindwa kwenqubo iyonke. Ukulawulwa kwe-solvent ethile kwenza ukwakheka kwezindandatho ze-pyrazole ezinezimpawu ze-elekthronikhi ezenzelwe ukusebenza kahle kwamaseli e-photovoltaic e-organic. Izicelo zemitha yobuningi obuphakathi, njengalezo ezinikezwa yi-Lonnmeter, zigcina izilinganiso ze-reactant ezihambisanayo futhi ziqapha imicimbi yokuguqulwa kwesakhiwo ngesikhathi sangempela. Le mitha yobuningi obuphakathi kwezinqubo zezimboni iqinisekisa ukuphathwa kwezinto okunembile, inciphisa ingozi yezingxenye eziphakathi ezingaphandle kwe-spec.
Isinyathelo ngasinye—kusukela ekujikeni, ekujikelezeni, kuya ekususeni kokugcina—sidinga ukulungiswa kobuningi besisombululo kanye nokuhlushwa ngenxa yokuzwela kwezicelo zendandatho ye-pyrazole ekusebenzeni kwe-OLED/OPV. Ukuhlanganiswa okulawulwayo kwama-intermediate ngokuqapha okuqhubekayo kuqinisekisa ukuthi izakhiwo ezisebenzayo zihlangabezana nezitayela zamadivayisi e-optoelectronic asezingeni eliphezulu.

Isizinda Sezimboni Esihlobene
Ama-photovoltaic e-organic asebenzisa izakhiwo zefilimu encane ezenziwe ngezinto ze-optoelectronic ze-organic ukuguqula ukukhanya kube ugesi. Ukusebenza kahle kwamaseli e-photovoltaic e-organic kuncike ekulawulweni okuqinile ngesikhathi sobuchwepheshe bokwenziwa kwezinto ze-organic, ikakhulukazi kuma-molecule aqukethe i-pyrazole. Ama-derivatives e-Pyrazolo[1,5-a]pyrimidine afaka isakhiwo sendandatho ye-pyrazole esithuthukisa ukuthuthwa kweshaja kanye nokukhishwa kwamadivayisi e-OLED kanye ne-OPV. Izinhlelo zokusebenza zemitha yobuningi obuphakathi zisekela ukulawulwa kwekhwalithi okuqhubekayo ngesikhathi sokwenziwa okukhulu, okuqinisekisa izilinganiso ezihambisanayo ze-reactant ezidingekayo ukuze idivayisi isebenze kahle.
KuyiniOi-rganicPama-hotovoltaic?
Ibhekisela kumadivayisi akhiwe ngamakhemikhali e-organic anezakhiwo ze-optoelectronic ezilungisekayo, anikeza ukuguquguquka kwemishini kanye nokwakhiwa okulula. Ukwenziwa kwe-acetone dicarboxylic acid kusebenza njengendlela ephakathi yokuhlanganisa indandatho ye-pyrazole, okubaluleke kakhulu ezintweni ezithuthukisiwe kanye nanjengezakhi zokwakha zemithi. Ukusetshenziswa kwe-acetone dicarboxylic acid kufaka phakathi ukukhiqizwa kwezinto ezahlukahlukene ze-pyrazole kumakhemikhali wezokwelapha kanye nezicelo ze-elekthronikhi. Ukuvumelana ezinqubweni zezimboni kuncike ekulinganisweni kwesikhathi sangempela ukuze kuhlangatshezwane nezitayela eziqinile zedivayisi ye-optoelectronic kanye nezindinganiso zokusebenza kahle.
Izinselele Ekulinganisweni Kobuningi Be-Inline
Ukulawulwa kwemitha yobuningi obuqondile kuhlale kunzima ekwakhiweni kwe-pyrazolo[1,5-a]pyrimidine ngenxa yokuncibilika okuphansi kwezinto eziphakathi kanye nemikhiqizo. Ukwenziwa kwe-acetone dicarboxylic acid kukhiqiza ama-derivatives endandatho ye-pyrazole angancibiliki kahle, okubangela ukumiswa kwezinhlayiya kanye nokufundwa kobuningi okungalindelekile. Ukwakheka kwezinhlayiya kuyanda ngesikhathi sokupholisa noma ukwakheka kwekristalu, okuphazamisa ukulinganiswa okuqhubekayo futhi kuthinte ubuqotho bomkhiqizo ezintweni ze-optoelectronic eziphilayo.
Ama-matrices okusabela ayinkimbinkimbi anezinyibilikisi eziningi kanye nama-reactant enza kube nzima kakhulu ukusetshenziswa kwemitha yobuningi obungaphakathi. Izilinganiso ze-reactant zishintsha ngokushesha; ukuguquguquka kobuningi kungabangelwa izinguquko zomzimba ezihambisanayo, hhayi nje ukushintsha kokuhlushwa. Ukuqina kanye nokushisa kuyahlukahluka njengoba izinyathelo ze-cyclization, condensation, kanye nokuhlanza zikhiqiza amaphrofayili e-exothermic noma e-endothermic, ikakhulukazi kumasu okwenziwa kwezinto eziphilayo aphezulu. Lezi zici ziphazamisa ukusebenza kahle kwamaseli e-photovoltaic e-organic futhi zenze ukulungiswa kokulinganisa kube yinto ebalulekile.
Ukwehlukaniswa phakathi kwe-pyrazole derivatives kuyimpoqo ngokwezitayela zamadivayisi e-optoelectronic e-organic kanye ne-photovoltaics e-organic. Ukuzwela okuphambene nemikhiqizo efana nesakhiwo kungonakalisa ukuzethemba kwedatha. Ukwanda kokusetshenziswa kudinga isikhathi esincane sokungasebenzi kahle kwemitha yobuningi be-inline yezinqubo zezimboni, kodwa ukuhlanza njalo kanye nokulinganisa kabusha akugwemeki lapho kucutshungulwa i-pyrazole derivatives eminingi ngokulandelana.
Izinzuzo Zokuhlanganisa Amamitha Obuningi Obungaphakathi/Amamitha Okugxila Ophakathi
Izinhlelo zokusebenza zemitha yobuningi obuphakathi zinikeza ukulawula okuqondile, kwesikhathi sangempela kokuhlushwa kwe-reactant kumasu okwenziwa kwezinto eziphilayo zezakhiwo zendandatho ye-pyrazole. Impendulo eqhubekayo isekela ukuhambisana kwenqubo, inciphisa ukuhlukahluka kwe-batch futhi iphakamisa ukuphindaphindeka ekhemistri yezokwelapha yezimboni kanye nokukhiqizwa kwezinto ze-optoelectronic eziphilayo. Amamitha obuningi obuphakathi ahlanganisiwe anciphisa ukusampula ngesandla—kunciphisa isidingo sabasebenzi kanye nokunciphisa izikhathi zomjikelezo eziphelele ngamaphesenti afinyelela ku-70 uma kuqhathaniswa nokuhlaziywa okungaxhunyiwe ku-inthanethi.
Ekukhiqizweni kwe-photovoltaics (OPV) yemvelo, ukulawulwa kokunemba okunikezwa amamitha obuningi obungaphakathi kukhulisa ukusebenza kahle kwamaseli e-photovoltaic emvelo, kugcina ukufana kokufakwa kwefilimu encane kanye nekhwalithi yesisombululo kulo lonke ukwenziwa kwemodyuli. Ukusetshenziswa kwezinsimbi ezingaphakathi kwe-Lonnmeter kunciphisa ama-batches angaphandle kwe-spec ngesikhathi sokwenziwa kwe-acetone dicarboxylic acid, kulondoloza isivuno kanye nezakhiwo zokusebenza ezibalulekile ekusetshenzisweni kwendandatho ye-pyrazole engezansi kanye nokusebenza kwedivayisi.
Izilinganiso zangaphakathi zesikhathi sangempela zisekela ukukhuliswa kwenqubo okusheshayo: imigqa yezimboni ingandisa ukukhiqizwa kwe-pyrazolo[1,5-a]pyrimidine derivatives ngaphandle kokulahla amazinga omkhiqizo noma ukufaneleka kwedivayisi kumadivayisi e-organic optoelectronic.
Cela ikhotheshini yokubhekana nezidingo zokulinganisa ubuningi obungaphakathi komugqa ekuhlanganisweni kwezinto eziphilayo ze-OLED kanye ne-photovoltaics eziphilayo nge-Lonnmeter inline density meter.Amathuluzi e-Lonnmeter ahlinzeka ngokwenziwa ngcono kwenqubo ngesikhathi sangempela kokwenziwa kwe-acetone dicarboxylic acid, ukwakheka kwesakhiwo sendandatho ye-pyrazole, kanye nokulawulwa kwezilinganiso ze-reactant ekukhiqizweni kwezinto ze-optoelectronic ze-organic ezisebenzisa amandla aphezulu.
