Qhov kev hloov pauv no tau txhim kho nws lipophilicity thiab kev xaiv tau xaiv, ua rau nws muaj zog thiab ntau yam lus thov kev sib koom tes thiab wb paub txog kev sib koom tes thiab ion tus kheej daim ntawv thov.

1. CATION nyuaj thiab Ion tus paub
● Qhov feem ntau siv los xaiv cov txuj ci ua hmoov av alkali hlau, tshwj xeeb tshaj yog cov poov tshuaj (k⁺) thiab sodium (NACH).
● Vim yog cov yas ether setcharat Atoms, nws cov ntaub ntawv ruaj khov nrog rau cations los ntawm encapsulating lawv nyob rau hauv nws lub nplhaib.
● Cov Dibenzo cov khoom ua pov thawj zoo dua li muaj peev xwm ntau dua thiab Liplophilicity, uas txhim kho kev xaiv thiab ruaj khov ntawm cov kev sib txawv hauv cov kuab tshuaj.
Piv txwv:
Actionical analistry: siv los rho tawm thiab ntes cov ntawv xov xwm ntawm cov hlau los ntawm cov sib tov sib xyaw.
● ion-de electrodes (ISES): Ua raws li kev ua siab ntev ntawm cov ntsuas ntawm membrant rau Ntsuas Ntsuas Cov Hlau Ion ntau.
2. Theem Hloov Cataly (PTC)
DuiSako -18- crown {{}}} {}}} {2}} {2} {2} Cations) ntawm aqueous mus rau cov theem organic.
Siv cov khoom siv hluav taws xob organic rau hauv organic qhov uas ionic reagents yuav tsum muaj kev cuam tshuam hauv cov xov xwm tsis yog.
Cov ntawv thov suav nrog:
Nucleophilic hloov cov kev coj ua
●xidations thiab txo cov ntsev
● Synthesis ntawm crown ether-hlau cov complexes rau catalysis
3. Supramolecular chemistry thiab cov tswv tsev-qhua lub tshuab
Ua si lub luag haujlwm tseem ceeb hauv supramolecular annistry ua tus tswv cuab kev paub txog kev kawm molecular lees paub, tus kheej sib dhos, thiab kev sib xyaw ua ke.
● nquag siv nyob rau hauv kev tsim cov tshuab molecular, tshuab thauj khoom, thiab hluavtaws receptors.
4. Sib cais kev tshawb fawb
● Siv hauv kua-ua kua extraction, khoom-theem rho tawm (thiab Membrane sib cais cov tswv yim rau kev xaiv rov qab cov hlau ions.
● Muaj txiaj ntsig zoo sib xws rau kev sib cais tab sis cov hluav taws xob sib txawv tab sis cov hluav taws xob sib txawv raws li qhov loj nrog cov yas kab noj hniav.
5. Khoom siv science thiab sensor tsim kho
● Cov koom ua ke rau hauv polymer matrices lossis nanostructured cov ntaub ntawv los txhim kho ion-findowSe sensors, ion-xaiv cov tshuaj txhuam, thiab cov khoom siv ntse.
● Pab kom tau txais kev xaiv thiab rhiab ntawm cov ntaub ntawv rau cov hlau ions.

1. Kev xaiv siab thiab affinity rau hlau ions
● Muab cov muaj zog thiab xaiv tau los ntawm cov alkali thiab alkaline ntiaj teb xas.
● Nws lub rings ringhates txhim kho lipophilicity, ua rau nws haum rau cov kev siv organic theem.
2. Versatility hauv synthesis thiab kev ntsuas aneverical
● Cov haujlwm uas yog ob qho tib si reagent thiab catalyst, ua rau muaj kev hloov cov tshuaj sib txawv thiab kev txhim kho cov tshuaj tiv thaiv kev loj hauv ntau theem.
● Nws qhov ruaj khov hauv cov kuab tshuaj hauv cov organic tso cai rau nws siv hauv cov txheej txheem batch thiab ntws tshuaj lom neeg.
3. Cov nqi hluav taws xob hauv molecular paub
● Ib lub hauv paus tseem ceeb hauv kev txhim kho cov khoom siv hluavtaws, cov tshuab hluav taws xob molecular, thiab ion thauj cov tshuab.
● Siv cov kev tshawb fawb hauv kev kawm tsis muaj kev sib raug zoo, xws li hydrogen tsev thiab ion-dipole kev sib cuam tshuam.
4. Kev ruaj khov thiab rov muaj tseeb
● Chemically ruaj khov nyob rau hauv ntau ntawm cov xwm txheej, ua rau nws haum rau kev rov siv dua hauv catalysis lossis kev sib cais cov txheej txheem.
● Nws lub thermal siab thiab tshuaj stability kuj pab nws siv hauv cov tshuab muaj kev nyab xeeb.
5. Txhim kho solubility thiab ua tau zoo muab piv rau niam txiv {1}} crown {2}}
● Lub benzene moises hauv dibenzo {{crowly {}}}}}}}} imp imp imp imp imp imp imp imp imp hauv cov duab teev, nthuav tawm nws cov ntawv thov kev ua tiav.
