Cette thèse est dédiée à l'exploration des surfaces d'énergie potentielle des états électroniques excités de colorants "ESIPT" (Excited-State Intramolecular Proton Transfer) à l'aide d'approches de chimie quantique. Le phénomène ESIPT s’observe typiquement dans des molécules présentant une liaison hydrogène intramoléculaire forte. Le changement de géométrie provoqué par ce transfert permet d’obtenir une grande différence entre l’absorption et l’émission (grand déplacement de Stokes), ouvrant la voie à de multiples applications. Le but de cette thèse est d'identifier les substituants les plus a

Abstract:

Excited state intramolecular proton transfer (ESIPT) reactions have aroused considerable interest in the last 10-15 years. The ESIPT reaction is normally extremely rapid and yields excited species of considerably lower energy than the initial Franck-Condon excited state. ESIPT has therefore been used for the rapid dissipation of energy (e. g. for polymer protection against UV degradation) and to produce fluorophores with large Stokes shifts. Approximately half of the compounds studied to date involve ESIPT to nitrogen but there has been no real attempt at a coherent study of ESIPT to nitrogen.

The photophysics of 2-(2'-hydroxyphenyl)benzothiazole (HBT) and related compounds has been studied as a function of solvent, pH or H 0 and temperature.

An investigation has been made into the protonation and deprotonation of 2-phenylbenzothiazole, 2-(2'-methoxyphenyl)benzothiazole), HBT and derivatives of HBT with bromine, chlorine, hydroxy, methoxy

Abstract:

Electron transfer, ET, and proton-coupled electron transfer, PCET, reactions are central to biological reactions involving catalysis, energy conversion and energy storage. The movement of electrons and protons in either a sequential or concerted manner are coupled in a series of elementary reaction steps in respiration and photosynthesis to harvest and convert energy consumed in foodstuffs or by absorption of light into high energy chemi-cal bonds in the form of ATP. These electron transfer processes may be modulated by conformational dynamics within the protein matrix or at the protein-protei

In the initial studies, no enantioselectivity was observed from the chiral photoacids to various chiral proton acceptors.

A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels.

For I-III,lactam-lactim tautomerization is both thermally and photonically inaccessible.Spectra evidence for 7-AI assisted lactam-lactim tautomerization of I and II is provided by the 7-AI tautomer emission (λ~480nmin cycloh

碩士<br>國立臺灣大學<br>化學研究所<br>102<br>In part I, we successfully obtained the bifunctional ortho- green fluorescence protein (o-HBDI) derivative, o-PyMeGFP, synthesized by Knoevenagel type reaction. Due to unstable conformation of o-MePyGFP; However, we successfully synthesized o-PyPhGFP via molecular adjustment. o-PyPhGFP underwent excited-state intramolecular proton transfer process via seven-membered-ring hydrogen-bonding system and its emssion at 607 nm. Also, ZnCl2 was reacted with o-PyPhGFP to form a complex, which destructed intramolecular H-bond and obtained blue emission. In part II, accord
