I-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid iyinhlanganisela ewusizo kakhulu emkhakheni we-organic chemistry kanye nesayensi yezinto ezibonakalayo.Iphuma ku-boronic acid enohlaka lwe-fluorene, okuyenza ibe ibhulokhi yokwakha eguquguqukayo yokuhlanganiswa kwama-molecule ahlukahlukene ezinto eziphilayo.Okunye okuphawulekayo kokusetshenziswa kwe-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid ukusetshenziswa kwayo ekunqandeni. -ukusabela kokuhlanganisa, ikakhulukazi ukuhlangana kwe-Suzuki-Miyaura.Lokhu kusabela kuhilela ukwakheka kwebhondi ye-carbon-carbon phakathi kwe-aryl noma i-vinyl halide ne-organoborane, eyenziwa yi-catalyst efanelekile.I-boronic acid moiety in9,9-Dimethyl-9H-fluoren-2-yl-boronic acid isebenza njengengxenye ye-organoborane, evumela ukuhlanganiswa kwezakhiwo eziyinkimbinkimbi eziphilayo.Le ndlela isetshenziswa kakhulu ocwaningweni lwesayensi yezemithi nezinto zokwakha, lapho ukwakheka kwebhondi ye-carbon-carbon kubalulekile ekukhiqizeni ama-molecule ahlosiwe anezindawo ezifiselekayo.Ngaphezu kwalokho, i-9,9-Dimethyl-9H-fluoren-2-yl-boronic acid iye yaba isetshenziswa ekwakhiweni kwama-semiconductors e-organic.Umgogodla we-fluorene unikeza ukuzinza okuhle kakhulu kwe-thermal kanye ne-photochemical kuma-molecule avelayo, okuwenza afanelekele ukusetshenziswa kwe-optoelectronic.Ngokuhlanganisa iqembu le-boronic acid, elinezinto zokuhoxiswa kwe-electron, izinhlanganisela eziwumphumela zibonisa izakhiwo ze-elekthronikhi ezithuthukisiwe, ezifana nokuhamba kweshaja okuthuthukisiwe kanye nokuhamba kahle.Lezi zakhiwo zifiseleka kakhulu ekusetshenzisweni kuma-organic light-emitting diode (OLED), i-organic field-effect transistors (OFETs), kanye namadivayisi we-organic photovoltaic (OPVs).Ngaphezu kwalokho, ukusebenza kwe-boronic acid ku-9,9-Dimethyl-9H-fluoren -2-yl-boronic acid inika amandla ukusetshenziswa kwayo kumakhemikhali we-supramolecular.I-Boronic acids inekhono eliyingqayizivele lokwenza izibopho ezihlehliswayo ze-covalent nama-diols, okuwenza abe amathuluzi abalulekile ekwakhiweni kwezinhlelo zamangqamuzana ashukumisayo.Le ndawo iye yaxhashazwa ekwakhiweni kwama-monolayer azihlanganisela wona, izinzwa zamangqamuzana, nezinhlelo zokulethwa kwezidakamizwa.Ngokuhlanganisa i-scaffold ye-fluorene, imihlangano ye-supramolecular ewumphumela ibonisa ukuzinza okuthuthukisiwe nokuguquguquka, inikeza amathuba amasha emkhakheni wesayensi yezinto zokwakha. i-organic synthesis, isayensi yezinto zokwakha, kanye ne-supramolecular chemistry.Isebenza njengebhulokhi yokwakha eguquguqukayo yokuhlanganiswa kwama-molecule e-organic eyinkimbinkimbi, isiza ukuthuthukiswa kwama-semiconductors e-organic asebenza kahle kakhulu, futhi inike amandla ukwakheka kwezinhlelo eziguquguqukayo ze-supramolecular.Imvelo yayo enemisebenzi eminingi iyenza ibe ithuluzi elibalulekile labacwaningi emikhakheni ehlukahlukene yesayensi.
