Abstract
Makrociklički spojevi definiraju se kao cikličke molekule, sastavljene od minimalno devet atoma od kojih minimalno tri moraju biti potencijalni donori elektrona. Zbog relativno jednostavne priprave kondenzacijskim reakcijama iz pogodnih amino ili formilnih prekurskora, Schiffove baze obećavajuće su u pripremi makrocikličkih spojeva. Povećanjem broja aldehidnih i amino skupina koje sudjeluju u reakcijama kondenzacije povećava se složenosti makrocikličkih Schiffovih baza. Možemo ih definirati kao rigidne makrocikliče molekule, koje imaju jasno definiranu unutarnju šupljinu u svojoj kristalnoj strukturi. Zbog porozne strukture makrocikle možemo svrstati u porozne materijale. Ovaj rad opisuje sintezu dviju makrocikličkih Schiffovih baza. Jedna baza dobivena je iz dialdehida 2-[5- (2-formilfenoksi)pentoksi]-benzaldehida i benzidina, dok je druga dobivena iz drugog dialdehida 2-[6- (2-formilfenoksi)heksoksi]-benzaldehida i istog diaminina benzidina. Strukture sintetiziranih spojeva utvrđene su nuklearnom magnetnom rezonancijom (NMR) i IR spektroskopijom (FTIR).
Abstract (english)
Macrocyclic compounds are defined as cyclic molecules composed of minimally 9 atoms, minimally 3 of which need to be potential electron donors. Due to relatively simple preparation through condensation reactions from suitable amino or formyl precursors, macrocyclic Schiff's bases are promising for preparation of macrocyclic compounds. By increasing the number of aldehyde and amino groups which participate in condensation reactions, the complexity of macrocyclic Shiff's bases also increases. They can be defined as rigid macrocyclic molecules which posess a clearly defined inner hollow in their cristal structure. Because of their porous structure, macrocycles can be regarded as porous materials. This paper describes a synthesis of two of the Schiff's bases. One of the bases is derived from dialdehyde (2-[5-(2-formylphenoxy)pentoxy]-benzaldehyde and diamine benzidine, the second is derived from dialdehyde (2-[6-(2-formylphenoxy)hexoxy]-benzaldehyde and the same diamine benzidine. The structures of the synthesised compounds are determined by nuclear magnetic resonance (NMR) and the IR spectroscopy (FTIR).
