1. Mai kara kuzarin canja wuri lokaci
(1) Ingantaccen haɓakar ƙwayoyin halitta: yana inganta haɓakar haɓakar haɓakawa da haɓaka haɓakar halayen iri-iri (kamar tsarin tsarin lokaci mai ƙarfi). Misali:
A cikin halayen haɓakar benzoin, ƙara 7% na 15-crown ether-5 na iya ƙara yawan amfanin ƙasa daga ƙasa kaɗan zuwa 78%.
A cikin hanyar haɗin gwiwar Wurtz don haɗa silane, ƙara 2% na 15-crown ether-5 na iya haɓaka yawan amfanin ƙasa daga 38.2% zuwa 78.8%, kuma rage lokacin amsawa ta sa'o'i 3.
(2) Nau'in amsawa masu dacewa: gami da maye gurbin nucleophilic, redox da halayen kwayoyin halitta na ƙarfe, musamman dacewa da halayen salts marasa narkewa (kamar potassium cyanide) a cikin abubuwan kaushi.
2. Additive Battery electrolyte
(1) Danne lithium dendrites: A cikin lithium baturi electrolytes, 15-crown ether-5 rage ion maida hankali a kan lantarki surface ta hadaddun lithium ions (Li⁺), inganta uniform ajiya. Gwaje-gwaje sun nuna cewa ƙara 2% na iya samar da santsi kuma mai yawa lithium jijiya Layer, kuma an tsawaita rayuwar sake zagayowar zuwa sau 178 (Li | Li | Batirin simmetric).
(2) Inganta jujjuyawar batirin lithium-oxygen: Tsara tsarin warwarewar Li⁺, haɓaka haɓakar ruɓarwar motsin Li₂O₂, da haɓaka jujjuyawar martanin.
(3) Aikace-aikacen batirin sodium-ion: Yi amfani da zaɓinsa na Na⁺ don haɓaka ingancin watsa sodium ion.
3. Metal ion rabuwa da ganowa
(1) Zaɓaɓɓen hakar: Yana da babban zaɓin iya bambanta ga cations kamar Na⁺ da K⁺, kuma ana amfani dashi don:
Maganin ruwan sharar ions masu nauyi (kamar mercury da uranium).
Farfado da abubuwan da ke da tasirin rediyo a cikin sharar nukiliya.
(2) Na'urori masu auna sigina: A matsayin kwayoyin ganewa, daidai yake gano takamaiman ions (kamar K⁺ da Na⁺) a cikin jini ko kuma mahalli mai tsananin hankali.
4. Kimiyyar likitanci da kayan aiki
(1) Masu ɗaukar ƙwayoyi: Yi amfani da haɓakar halittunsa (wasu abubuwan da suka samo asali kamar 2-hydroxymethyl-15-crown ether-5) don cimma isar da magunguna da aka yi niyya da sakin sarrafawa.
(2) Shiri na ruwa mai laushi: A matsayin mai kaushi, haɗe tare da polyhedrons na ƙarfe na ƙarfe (kamar MOP-18) don samar da ruwan zafi na ɗaki don rabuwa ko ajiya.
5. Sauran aikace-aikacen masana'antu
(1) Rini kira: Inganta hanyar amsawa don inganta tsaftar rini da yawan amfanin ƙasa8.
(2) Ƙarfe mai daraja: A matsayin ligand don haɓaka aiki da kwanciyar hankali na masu kara kuzari irin su platinum da palladium, da rage yawan karafa masu daraja da ake amfani da su.
