Ülevaade
Supramolekulaarse keemia uurimisrühm tegeleb uute käeliste uureapõhiste molekulaarsete mahutite arendamisega. Tegeleme efektiivsete ja keskkonnasõbralike sünteesimeetodite välja töötamisega, kasutades muuhulgas mehhanokeemiat. Uurime molekulide ja supramolekulaarsete kompleksite struktuure ning molekulidevaheli vastasmõjusid. Keskendume kukurbituriilide perekonda kuuluvatele makrotsüklitele – hemikukurbituriilidele, ning nende kompleksidele. Eriti huvitume heade optiliste omadustega porpfüriinide kompleksitest ning nende rakendamisest supramolekulaarsetes süsteemides. Uurime kiraalse induktsiooni teket ning supramolekulaarsete komplesite spektroskoopilisi iseärasusi. Nii saame valmistada adaptiivseid sensoreid ning välisstiimulitele reageerivaid ise-organiseeruvaid molekulide süsteeme. Uute molekulaarsete mahutite disaini abil on võimalik välja töötada uusi rakendusi nii materjali- ja keskkonnateaduses, kui ka toidu-, farmaatsia- ning põllumajandustööstusele. Uurimisrühm panustab uute tehnoloogiate välja töötamisse üleeuroopalises teadlaste ja ettevõtjate konsortsiumites: https://www.project-initio.eu/ ja COST MechSustInd.
Tähtsamad tulemused
2023. aasta silmapaistvaim publikatsioon ilmus mõjukas keemiaajakirjas, Angewandte Chemie International Edition, kus näidati, et süsinik-süsinik sidet saab väga reaktiivsete metallide juuresolekul tekitada ka vähese energiakuluga, toatemperatuuril ning tahkes faasis. See teadusuudis leidis ära märkimist „kuuma artikli“ tiitliga ning illustreeriti ajakirja kaanepildil.EL tulevaste siirdetehnoloogiate arendamise projektis (H2020 FET-OPEN, INnovative chemIcal sensors for enanTioselective detectIon of chiral pOllutants) leidsid TTÜs väljatöötatud hemikukurbituriilid rakendust saasteainete tuvastamisel ja elektroonilistes ninades. Projekti tulemusena anti sisse ka patentse leiutise taotlus (EP23181344.5).
