Tarkoituksena oli tarkastella erilaisten synteesiolosuhteiden vaikutusta synteesierien lopputuotteeseen. Toisena vaiheena ty\u00f6ss\u00e4 valmistettiin sarja haihdutuskiteytyksi\u00e4, mink\u00e4 tavoitteena oli valmistaa mahdollisia uusia MOF-rakenteita. Haihdutuskiteytyksiss\u00e4 k\u00e4ytetiin metallisuola- ja ligandiliuoksia, jotka olivat vesi- tai metanolipohjaisia. Metallisuolat olivat kupari- tai sinkkipohjaisia. K\u00e4ytetyist\u00e4 ligandeista kahta eri 1,4-diatsabisyklo[2.2.2]-oktaani-pohjaista ligandia on jo aiemmin k\u00e4ytetty MOF-synteeseiss\u00e4, mutta kirjallisuuden perusteella 4-(bromometyyli)bentsoehappo-pohjaisen ligandin k\u00e4yt\u00f6st\u00e4 on raportoitu vain muutamia kertoja.
