Investigation of photophysical behaviours and antimicrobial activity of novel benzo-15-crown-5 substituted coumarin and chromone derivatives

Gül, Duygu Sahin; Öğütçü, Hatice; Hayvali, Zeliha (Elsevier, 2020)

Two different series of crown ether compounds (4-11) were synthesized by the reactions of 4',5'-bis(bromomethyl)benzo-15-crown-5 (3) and 4'-amino-benzo-15-crown-5 with hydroxycoumarin and chromone derivatives. Coumarin-crown ...
Novel bis-crown ethers and their sodium complexes as antimicrobial agent: synthesis and spectroscopic characterizations

Hayvali, Zeliha; Guler, Huseyin; Ogutcu, Hatice; Sari, Nursen (SPRINGER BIRKHAUSER, 2014)

A series of new compounds containing formyl and imine group were synthesized. New formyl-substituted compounds were prepared by the reaction of 1,2-bis(bromomethyl)benzene with benzaldehyde derivatives in the presence of ...
Photophysical and antimicrobial properties of new double-armed benzo-15-crown-5 ligands and complexes

Kocoglu, Serhat; Ogutcu, Hatice; Hayvali, Zeliha (SPRINGER, 2019)

New double-armed crown ether ligands linked to pyridine derivatives have been synthesized and characterized. These macrocyclic ligands (1-5) have been synthesized by the reactions of 4,5-bis(bromomethyl)benzo-15-crown-5 ...
