Iimveliso

I-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid yinto eluncedo kakhulu kwintsimi ye-organic chemistry kunye nesayensi yezinto.I-boronic acid derivative kunye ne-fluorene skeleton, eyenza ibhloko yokwakha eguquguqukayo yokudibanisa iamolekyu ezahlukeneyo zezinto eziphilayo.Isicelo esiphawulekayo se-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid kukusetyenziswa kwayo kwi-cross. -impendulo zokudibanisa, ngakumbi iSuzuki-Miyaura coupling.Le mpendulo ibandakanya ukubunjwa kweebhondi ze-carbon-carbon phakathi kwe-aryl okanye i-vinyl halide kunye ne-organoborane, eququzelelwa yi-catalyst efanelekileyo.I-boronic acid moiety in9,9-Dimethyl-9H-fluoren-2-yl-boronic acid isebenza njengenxalenye ye-organoborane, evumela ukuhlanganiswa kwezinto eziyinkimbinkimbi zezinto eziphilayo.Le ndlela isetyenziswa ngokubanzi kuphando lwenzululwazi yamayeza kunye nezixhobo, apho ukubunjwa kweebhondi zekhabhoni-carbon kubalulekile ekuveliseni iimolekyuli ezijoliswe kuzo ezineempawu ezifunwayo.Ngaphezu koko, i-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid iye yafunyanwa. isetyenziswe kuphuhliso lwe-organic semiconductors.Umqolo we-fluorene unika uzinzo oluhle kakhulu lwe-thermal kunye ne-photochemical kwiimolekyuli ezibangelwayo, zibenze zilungele ukusetyenziswa kwe-optoelectronic.Ngokubandakanya iqela le-boronic acid, elineempawu zokurhoxiswa kwe-electron, iikhompawundi ezibangelwayo zibonisa iimpawu ze-elektroniki eziphuculweyo, ezifana nokuphuculwa kokuhamba kwentlawulo kunye ne-conductivity.Ezi zakhiwo zinqweneleka kakhulu kwizicelo kwi-organic light-emitting diodes (OLEDs), i-organic field-effect transistors (OFETs), kunye nezixhobo ze-organic photovoltaic (OPVs) .Ngaphezu koko, ukusebenza kwe-boronic acid kwi-9,9-Dimethyl-9H-fluoren -2-yl-boronic acid yenza isicelo sayo kwi-supramolecular chemistry.I-Boronic acids inesakhono esikhethekileyo sokwenza i-covalent bonds eguqukayo kunye ne-diols, ezenza zibe zixhobo ezixabisekileyo ekuyilweni kweenkqubo ze-molecular dynamic.Le propati iye yaxhatshazwa ekuphuhliseni i-monolayers ezidibeneyo, i-molecular sensors, kunye neenkqubo zokuhanjiswa kweziyobisi.Ngokubandakanya i-scaffold ye-fluorene, iindibano ze-supramolecular ezibangelwayo zibonisa uzinzo oluphuculweyo kunye nokuguquguquka, ukunika amathuba amatsha kwintsimi yesayensi yezinto. i-organic synthesis, isayensi yezixhobo, kunye ne-supramolecular chemistry.Isebenza njengebhloko yokwakha eguquguqukayo yokwenziwa kweeathomli ze-organic ezintsonkothileyo, iququzelela uphuhliso lwe-semiconductors ye-organic esebenza kakhulu, kwaye yenza uyilo lweenkqubo eziguqukayo ze-supramolecular.Ubume bayo bemisebenzi emininzi buyenza ibe sisixhobo esibalulekileyo kubaphandi kwiinkalo ezahlukeneyo zenzululwazi.
