Kusiyana kwa Fullerene C60 ndi Fullerene C70 kwapangidwa kukhala kosavuta

Mfundo Zofunika Kwambiri

• Fullerene C60 ndi yokhazikika komanso yochuluka, pomwe C70 ili ndi zinthu zapadera zomwe zimapangitsa kuti ikhale yothandiza pa ntchito zapamwamba.
• C60 ili ndi mawonekedwe ozungulira okhala ndi maatomu 60 a kaboni, pomwe C70 ili ndi maatomu 70 a kaboni, zomwe zimakhudza momwe amagwirira ntchito komanso kuyamwa kwa kuwala.
• Ma fullerenes onsewa amagwiritsidwa ntchito kwambiri mu zamankhwala ndi ukadaulo, ndipo C60 ndi yabwino kwambiri pogwiritsira ntchito mano ndi C70 mu maselo a dzuwa ogwira ntchito bwino kwambiri.

Kusiyana kwa Kapangidwe ka Fullerene C60 ndi Fullerene C70

Kuyerekeza Mawonekedwe ndi Kukula

Mukhoza kuona kusiyana pakati pa Fullerene C60 ndi Fullerene C70 poyang'ana mawonekedwe ndi kukula kwawo. C60 imapanga mawonekedwe otchedwa icosahedron yodulidwa. Mawonekedwe awa amaoneka ngati mpira wa mpira, wokhala ndi ma pentagons 12 ndi ma hexagons 20. C70 yatambasuka Mu khola la ellipsoidal, zomwe zikutanthauza kuti ndi lalitali komanso lozungulira pang'ono kuposa C60. Lili ndi ma pentagon 12 ndi ma hexagon 25. Kukula kwa C60 ndi pafupifupi ma nanometer 0.7 m'lifupi. C70 imalemera pafupifupi ma nanometer 0.71 ndi ma nanometer 0.79, zomwe zimapangitsa kuti ikhale yayikulu pang'ono komanso yozungulira kwambiri.

Nayi tebulo lomwe likuwonetsa kusiyana kumeneku:

Langizo: Mungakumbukire kuti C60 ndi yozungulira ngati mpira, pomwe C70 imapangidwa ngati mpira wa rugby.

Makonzedwe a Maselo

Mukayang'ana bwino kapangidwe ka mamolekyu, mukuwona kuti Fullerene C60 ndi Fullerene C70 zonse zimagwiritsa ntchito maatomu a kaboni popanga ma cage awo. Momwe maatomu awa amalumikizirana amasintha mawonekedwe a molekyulu iliyonse. C60 ili ndi kulinganiza kwakukulu, komwe kumapangitsa kuti ikhale yokhazikika. C70 ili ndi kulinganiza kochepa chifukwa imatambasuka ndikuwonjezera ma hexagon ambiri. Kusinthaku kwa kulinganiza kumakhudza momwe mamolekyu amagwirira ntchito.

Nayi tebulo lomwe likuwonetsa kapangidwe ka ma pentagons ndi ma hexagons:

Mukhozanso kuona kusiyana kwa mndandanda wosavuta:

• C60 ili ndi ma pentagons 12 ndi ma hexagons 20.
• C70 ili ndi ma pentagon 12 ndi ma hexagon 25.

Ma hexagon owonjezera mu C70 amaswa kusinthasintha komwe kumapezeka mu C60. Njirayi imasintha mawonekedwe amagetsi ndikupangitsa C70 kuyamwa kuwala pamlingo wokulirapo. Asayansi amagwiritsa ntchito deta ya spectroscopic kuti aphunzire kusinthaku. Kusintha kuchokera ku C60 kupita ku C70 kumaphatikizapo kusweka kwa kusinthasintha, komwe kumakuthandizani kumvetsetsa momwe ma cage akuluakulu a fullerene amapangikira.

Dziwani: C60 ndi C70 zonse zimagwira ntchito ngati ma elekitironi olandirira. Zimasonyeza ma redox angapo ndipo zimayamwa kwambiri mu UV-visible spectrum. Zinthu zimenezi zimapangitsa kuti zikhale zothandiza m'maselo a dzuwa ndi zipangizo zina zamagetsi.

Fullerene C60 ndi Fullerene C70 ali ndi mawonekedwe ndi makonzedwe apadera. Kusiyana kumeneku kumakuthandizani kusankha molekyu yoyenera polojekiti yanu.

Kapangidwe ka Thupi ndi Mankhwala a Fullerene C60 ndi Fullerene C70

Kukhazikika

Mungadabwe kuti mamolekyu amenewa ndi okhazikika bwanji. Fullerene C60 ndi Fullerene C70 zonse zikuwonetsa kukhazikika kwamphamvu, makamaka mukawateteza ku kuwala kwamphamvu kapena kutentha. Kapangidwe kawo kapadera konga khola kamawathandiza kuti asasweke. Mukawaunikira m'madzi, mitundu yonse iwiri imasunga kuyamwa kwawo kwa UV-vis kosasintha kwa maola asanu. Izi zikutanthauza kuti samasweka mosavuta pansi pa kuwala. Asayansi amatcha izi kukhala ndi photostability. Mutha kukhulupirira kuti ma fullerenes onsewa amasunga mawonekedwe awo panthawi yoyesera yambiri.

Zindikirani: Kukhazikika kwambiri kwa kuwala kumapangitsa kuti ma fullerenes awa akhale othandiza m'maselo a dzuwa ndi zida zina zomwe zimafunika kukhala nthawi yayitali.

Kuchitanso zinthu mwachibadwa

Mudzapeza kuti Fullerene C60 ndi Fullerene C70 zimayanjana ndi mankhwala ena m'njira zosiyanasiyana. Mawonekedwe ndi kufanana kwa molekyulu iliyonse zimakhudza momwe zimachitira. C60 ili ndi mawonekedwe ozungulira komanso kufanana kwakukulu. Izi zimapangitsa kuti ikhale ndi malo ochepa oti machitidwe a mankhwala achitike. C70 ili ndi mawonekedwe ataliatali okhala ndi kufanana kochepa. Izi zimapangitsa kuti pakhale malo ambiri ochitira zinthu.

Mukawonjezera gulu limodzi la mankhwala ku C60, mumapeza ma isomer awiri okha omwe angatheke. Ndi C70, mutha kupeza ma isomer asanu ndi atatu. Tebulo ili pansipa likuwonetsa kusiyana kumeneku:

Mutha kuona kuti C70 imapanga zinthu zovuta kwambiri mukaigwiritsa ntchito ndi mankhwala ena. Izi zimapangitsa kuti C70 ikhale yothandiza mukafuna kupanga zinthu zatsopano zokhala ndi makhalidwe apadera.

Kusungunuka

Mungafunse kuti ma fullerene awa amasungunuka bwino bwanji m'madzimadzi. Fullerene C60 ndi Fullerene C70 zonse zimasungunuka bwino kwambiri m'zinthu zosungunulira zachilengedwe monga toluene ndi benzene. C60 nthawi zambiri imasungunuka bwino kuposa C70. Gome ili pansipa likuwonetsa kuchuluka kwa ma fullerene aliwonse omwe mungasungunuke m'zinthu zosungunulira izi:

Mungathe kuona kuti C60 imasungunuka kawiri kuposa C70 mu toluene. Mu benzene, kusiyana kwake ndi kochepa, koma C60 imasungunukabe bwino pang'ono.

• Kusungunuka kwa ma fullerenes onse awiri sikukwera nthawi zonse mukatentha madziwo.
• Mudzaona kuti kusungunuka kumafika pachimake pa kutentha kwa chipinda.
• Ngati mutentha kwambiri yankho, ma fullerenes amayamba kutuluka mumadzimadzi.
• Izi zimachitika chifukwa cha kusintha kwa momwe mamolekyu amagwirizanirana komanso momwe amagwirira ntchito ndi chosungunulira.

Langizo: Ngati mukufuna kusungunula fullerene yambiri, yesani kusunga kutentha pafupi ndi kutentha kwa chipinda.

Fullerene C60 ndi Fullerene C70 ali ndi makhalidwe osiyanasiyana a thupi ndi mankhwala. Mutha kugwiritsa ntchito kusiyana kumeneku kuti musankhe molekyu yoyenera polojekiti yanu. Kukhazikika kwawo, kuchitapo kanthu kwawo, komanso kusungunuka kwawo zonse zimagwira ntchito pa momwe mumagwiritsira ntchito mu sayansi ndi ukadaulo.

Kugwiritsa Ntchito Kawirikawiri kwa C60

Mudzapeza Fullerene C60 m'mafakitale ambiri azachipatala ndi kugwiritsa ntchito zamagetsi. Mu zamankhwala, C60 imathandiza kukonza zinthu za mano ndikuzipangitsa kukhala nthawi yayitali. Imaletsanso matenda komanso imachepetsa kutupa mkamwa. C60 imatha kunyamula mankhwala mkati mwa thupi lanu ndikutulutsa pang'onopang'ono, zomwe zimathandiza kulunjika ku maselo ena. Asayansi amagwiritsa ntchito C60 ngati antioxidant polimbana ndi ma free radicals omwe amayambitsa ukalamba ndi matenda. Kafukufuku akupitiliza kufufuza momwe imagwiritsidwira ntchito pa khansa ndi matenda a ubongo.

Nayi tebulo lomwe likuwonetsa momwe C60 imapindulira madera a mano ndi azachipatala:

Mungapezenso C60 mu maselo a dzuwa ndi zamagetsi chifukwa ndi yokhazikika komanso yotsika mtengo.

Kugwiritsa Ntchito Kawirikawiri kwa C70

Fullerene C70 ili ndi ntchito zapadera chifukwa cha mawonekedwe ake apadera komanso makhalidwe ake. Mudzawona C70 m'maselo apamwamba a dzuwa, komwe imayamwa kuwala kwa dzuwa kwambiri ndikupangitsa maselo kukhala ogwira ntchito bwino. C70 imagwiranso ntchito bwino mu ma photodetector ndi ma nonlinear optics, omwe ndi ofunikira pazida zamakono. Mu zamankhwala, C70 imathandiza kupereka mankhwala ndipo imatha kuchiza khansa pogwiritsa ntchito kuwala (photodynamic therapy). Zodzoladzola zina zimagwiritsa ntchito C70 kuti zichepetse kukalamba kwa khungu.

Nazi njira zazikulu zomwe C70 imagwiritsidwira ntchito:

• Maselo a dzuwa opangidwa ndi mphamvu kwambiri
• Zowunikira zithunzi zomwe zimakhala ndi mphamvu zambiri
• Chithandizo cha Photodynamic cha khansa
• Machitidwe operekera mankhwala
• Zodzoladzola zoletsa kukalamba
