Photophysical Properties of Binuclear and Trinuclear Monovalent Coinage Metal Complexes for Applications in Molecular Devices

Description: Monovalent coinage metal complexes have been of significant interest due to their rich photophysical properties. This dissertation focuses on the design, synthesis, and characterization of gold, silver, and copper phosphors. Chapter 2 investigates new physical and photophysical properties of a gold diphosphine dimer in the solid state. Thermally activated luminescence switching between two structural states is discussed. Chapter 3 includes the photochemistry of closed shell group 11 transitio… more

Optoelectronically Active Metal-Inorganic Frameworks and Supramolecular Extended Solids

Description: Metal-organic frameworks (MOFs) have been intensely researched over the past 20 years. In this dissertation, metal-inorganic frameworks (MIFs), a new class of porous and nonporous materials using inorganic complexes as linkers, in lieu of traditional organic linkers in MOFs is reported. Besides novel MIF regimes, the previously described fluorous MOF "FMOF-1", is re-categorized herein as "F-MIF1". F-MIF-1 is comprised of [Ag4Tz6]2- (Tz = 3,5-bis-trifluoromethyl-1,2,4-triazolate) inorganic clust… more

Synthesis, Characterization, Standardization, and Validation of Luminescence Optical Chemosensors for the Detection of Carbon Dioxide, Aluminum Ions, and Silver Ions for Real-Life Applications

Description: The presented dissertation encompasses three distinct investigations into novel complexes with diverse applications. Firstly, a Europium-based complex, K[Eu(hfa)4], exhibits remarkable potential for detecting dissolved CO2 in an ethylene glycol medium, offering a low limit of detection, rapid response times, and high signal-to-noise ratios. This complex demonstrates promise for quantifying CO2 concentrations and finds utility in sugar fermentation monitoring. Secondly, an innovative ratiometric… more

Microwave-Assisted Synthesis and Photophysical Properties of Poly-Imine Ambipolar Ligands and Their Rhenium(I) Carbonyl Complexes

Description: The phenomenon luminescence rigidochromism has been reported since the 1970s in tricarbonyldiimine complexes with a general formula [R(CO)3LX] using conventional unipolar diimine ligands such as 2,2;-bipyridine or 1,10-phenanthroline as L, and halogens or simple solvents as X. As a major part of this dissertation, microwave-assisted synthesis, purification, characterization and detailed photoluminescence studies of the complex fac-[ReCl(CO)3L], 1, where L = 4-[4,6-bis(3,5-dimethyl-1H-pyrazol-1-… more
