Fluorescent sensors for metal ions
… Using the "dual fluorescence" properties of TICT state compounds (Twisted Intramolecular Charge Transfer which gives an extra red-shifted emission band) and the key property of crown ether compounds which is their ability to complex ions, we designed and synthesised a range of new …

Femtosecond Laser Interactions In The Condensed Phase: Application to Transient Absorption and Materials Processing
… The possibility of the formation of TICT states is also discussed. Ultrafast laser ablation has been studied for a variety of dielectric, semiconducting and metallic substrates with emphasis on the development of the technique for rapid prototyping of micro-fluidic devices. Some …

The Development of 2,3-Diarylindenes as Integrated Fluorescent Estrogens
… a twisted intramolecular charge transfer (TICT) state with emission up to 690 nm in chloroform. A nitro group in the m-position or a nitro, bromo, or cyano group in the p-position of the 2-ring all greatly reduce estrogen receptor binding affinity. A hydroxy group in the p-position of the …

Quantum-Mechanical Investigations of Excited State and Catalytic Properties of Organic Luminophores and Zeolites
… and twisted intermolecular charge transfer (TICT) states. Lastly, as a capstone to this thesis, we developed a new double hybrid density functional approximation (DH-DFA), ωB88PTPSS, which incorporates the equipartition of density functional theory (DFT) and non-local correlation but with a …

Synthesis and Evaluation of New Antimicrobial Agents and Novel Organic Fluorophores
… via twisted intramolecular charge transfer (TICT) states. The biphenyl N,N-dimethyl-4'-(phenylsulfonyl)-[1,1'-biphenyl]-4-amine was found to show a very high quantum yield in toluene and dichloromethane (Φ close to 0.9); large Stokes shifts and high molar extinction coefficient in ethylene …

A study of the solution photophysics of the isomeric aminobenzoic acids, N, N-dimethylaminobenzoic acids and their methyl esters
… observations were tested; excimer, exciplex, TICT state and ground state dimer formation. The latter was found to be in best accord with the properties of these molecules, but it was clear that in binary solvent mixtures such as hexane / acetonitrile and acetonitrile / water other mechanisms …

Epindolidione, Epindoline und lineare sowie trigonale Imidazolderivate
… auf, da die Intensität der Fluoreszenz durch TICT-Zustände abgeschwächt wird. In den Absorptionsspektren aber noch stärker ausgeprägt in den Fluoreszenzspektren der Verbindungsklassen 115 und 119 ist eine positive Solvatochromie feststellbar. Für die Verbindungsklasse 124 findet man nur eine …

Synthesis of Fluorescent Molecules and their Applications as Viscosity Sensors, Metal Ion Indicators, and Near-Infrared Probes
The primary focus of this dissertation is the development of novel fluorescent near-infrared molecules for various applications. In Chapter 1, a compound dU-BZ synthesized via Sonogashira coupling reaction methodology is described. A deoxyuridine building block was introduced to enhance hydrophilic …
