    Synthesis and Characterization of New Metal- Organic Framework Derived from 6- (Methoxycarbonyl) Pyridine-2-Carboxylic Acid as Application for Hydrogen Storage Materials
    (International Journal of Applied Chemistry, 2016) Maisara Abdul Kadir; Nafisah Mansor; Wan M. Khairul; Mohd Sukeri Mohd Yusof; Mohammad Ismail
    In this study, a new organic linker namely 6-(pyrimidin-2-ylcarbamoyl)-pyridine-2- carboxylic acid methyl ester (L1) has been successfully synthesized. Along with this discovery, two metal-organic frameworks (MOFs) which derived from L1 and 6- (methoxycarbonyl)pyridine-2-carboxylic acid (L), have also been synthesized and characterized by using combination of spectroscopic techniques such as Infrared (IR), Nuclear Magnetic Resonances (NMR), Thermal Gravimetric Analysis (TGA) and Xray crystallography.

    Synthesis and coordination chemistry of polypyridyl amide ligands
    (Australia: The University of Adelaide, 2012-09) Maisara Abdul Kadir
    This thesis provides an account of the synthesis and study of fifteen amide-containing polypyridyl ligands, eleven of which are new compounds. These ligands all possess at least one amide moiety, potentially capable of anion binding and one or more pendant pyridyl donor groups as the metal coordinating sites. A further evolution over previously reported compounds is that a majority of the amide compounds incorporate a pre-organised amide component that will constitute the anion binding region.

    Theoretical And Experimental Investigation Of Pyridylthiourea Derivatives As Ionophores For Cu(ii) Ion Detection
    (Malaysian Journal of Analytical Sciences, 2015-12) Wan M. Khairul; Mohd Faizuddin Abu Hasan; Adibah Izzati Daud; Hafiza Mohamed Zuki; Ku Halim Ku bulat; Maisara Abdul Kadir
    Copper (II) ion chemical sensors based on pyridine-thiourea derivatives; N-pyridyl-N’-(biphenyl-4-carbonyl)thiourea (L1), and N-pyridyl-N’-(3,5-dimethyoxybenzoyl)thiourea (L2) were synthesised, characterised, and studied as ionophores in the form of thin-films PVC membranes.

    UV-Vis Spectroscopic Studies of Diamide Ligands as Potential Tools for Anion Sensor
    (EDUCATUM Journal of Science, Mathematics and Technology (EJSMT), 2016) Maisara Abdul Kadir; Mohamad Nur Azshary Mohd Salleh; Nur Syazwani Kassim
    This paper describes the results from ultraviolet (UV) spectroscopic studies of diamide ligands namely N,N’-2,6- bis(3-pyridylmethyl)pyridine dicarboxamide (L5) and N,N’-2,6-bis(4-pyridylmethyl)pyridine dicarboxamide (L6) towards chloride, nitrate and chromate anions in solution. The responses of the ligands towards anions are monitored by the changes of the absorbance in the UV spectra. The time interval experiments were conducted from 0 to 3 hours, resulted to the rise of the absorbance of the ligands. The change in the absorbance value is attributed to the increase of interaction between the ligands and anions that is proportional with time. In contrast to the ligands, the absorbance of anion is decreased showing the reduction of anion concentration in the solution. Rapid UV response indicates the sensitivity of these ligands towards anions which at the same time showing promising potential as sensitive anion sensor.
