Projekti eesmärgiks on märkimisväärne arenguhüpe superhapete ja superaluste keemias. Olulisimad kavandatud tulemused: (1) Uute superhapete/superaluste disain, süntees ja happelisuse/aluselisuse mõõtmine viivad rea uute superhapete/superaluste loomiseni, happelisuse/aluselisuse põhjuste sügavama mõistmise ja superhapete/superaluste tugevuste seniste "kasvupiiride" murdmiseni; (2) Gaasifaasilised superhappelisuse ja superaluselisuse skaalad laienevad ning seotakse omavahel, misläbi osutub esmakordselt võimalikuks ühendatud eksperimentaalse gaasifaasilise happelisuse-aluselisuse skaala koostamine; (3) Absoluutse pH skaala (pHabs) kontseptsioon realiseeritakse eksperimentaalselt misläbi osutub esmakordselt võimalikuks mistahes keskkondade (sh superhapete/superaluste) happelisuste vahetu võrdlemine; (4) Ülitugevate karboraanhapete H(CB11H12) derivaatide saamiseks luuakse efektiivne sünteesitee ja seeläbi avanevad võimalused nende ainete kõrgtehnoloogilisteks rakendusteks.
The project aims at a radical leap forward and partial redefinition of the chemistry of superacids and superbases. Highlights: (1) New superacids and superbases will be designed, synthesized and their acidity/basicity measured. New knowledge will be gained on their optimal electronic structure, which is expected to lead to breaking the existing "limits of growth" for the acidity or basicity of superacids and superbases; (2) Extending the gas-phase superacidity and superbasicity scales and interlinking them for the first time with a series of spontaneous gas-phase proton transfer experiments between neutral superacids and superbases; (3) The concept of unified solution pH scale (pHabs) will be experimentally realized enabling direct comparison of acidities/basicities of any media incl superacidic and superbasic media; (4) Efficient synthetic route will be designed for the ultrastrong carborane acids - derivatives of H(CB11H12) - and their hi-tech application potential will be explored.
