Abstract:

One antiaromatic polycyclic hydrocarbon (PH) with and without solubilizing tert-butyl substituents, namely s-indaceno[2,1-a:6,5-a′]dipyrene (IDPs), has been synthesized by a four-step protocol. The IDPs represent the longitudinal, peri-extension of the indeno[1,2-b]fluorene skeleton towards a planar 40 π-electron system. Their structures were unambiguously confirmed by X-ray crystallographic analysis. The optoelectronic properties were studied by UV/vis absorption spectroscopy and cyclic voltammetry. These studies revealed that peri-fusion renders the IDP derivatives with a narrow optical ener

Abstract:

Metal Organic Frameworks (MOFs) are a type of multifunctional porous material. Comprised of metal centres or metal clusters known as Secondary Building Units (SBUs) linked together into an extended 1, 2 or 3 dimensional structure by bridging organic ligands coordinated to the metal SBUs. MOFs offer the opportunity to customise the pore size and chemical functionality of the fra mework. The degree of customisation possible from the wide array of different metal clusters and organic ligands MOFs have been proposed for many applications such as gas storage, separation, catalysis, photocatalysis,

Abstract:

Carbohydrates are displayed on the outer layer of cells by glycoproteins and glycolipids, forming the glycocalyx. These carbohydrates hold a huge amount of information, acting as a cell 'barcode', facilitating communication and acting as targets for pathogens. The proteins which recognise carbohydrates in nature are called lectins. Synthetic mimics of these proteins, binding through noncovalent interactions in water, are termed 'synthetic lectins'. The design and synthesis of these synthetic lectins could allow reading of parts of the cell barcode and give a greater understanding of the operat

Abstract:

The luminescence properties of Van Der Waals' dimers and clusters of pyrene and diazapyrene have been investigated. Excimers, dimeric species which are associative in an excited electronic state and dissociative in their ground state, have long been established and play an important role in many areas of photochemistry. My work here focuses on the luminescence and absorption properties of ground state dimers/aggregates, which are less understood, and allows further characterization of the ground state and excited state association of these aromatic molecules.

Abstract:

Understanding the thermodynamic properties of multicomponent mixtures is of critical importance in many chemical and industrial applications. Experimental measurements become progressively difficult as the number of solution components increases -- producing the need for predictive models. Problems in development of predictive models arise if the mixture has one or more components that interact through molecular complexation or association. Experimental solubilities of anthracene and pyrene dissolved in binary systems containing one or more alcohols were measured in order to address this prob

In contrast, derivatives substituted at the 2- and 2,7-postions of pyrene are rare, as their syntheses involve laborious multistep processes.

Abstract:

Abstract The tumour suppressor gene TP53 is the most commonly mutated gene in human cancers. The protein it codes, p53, becomes activated as a response to stress signals. When activated, p53 binds to DNA and affects the transcription of its target genes. They then cause cell cycle arrest, DNA repair and/or induction of programmed cell death, thus preventing mutations and cancer. Specific mutations in TP53 are associated with exposure to certain carcinogens, such as polycyclic aromatic hydrocarbons (PAHs). These environmental chemical carcinogens are formed through incomplete combustion of orga

Abstract:

碩士<br>國立清華大學<br>化學系<br>103<br>Chromophoric initiator containing pyrene moiety was synthesized and was used to the normal and photo-induced ATRP of various monomers to obtain the flourscent polymer. These well-controlled dye-labeled polymer showed a low polydispersity (Mw / Mn = 1.20 ~ 1.30), and could form the diblock copolymers. Photo-induced or Photo-mediated ATRP was performed in our study. Photo-induced ATRP is an efficient or economical method for methyl acrylate, methyl methacrylate and styrene polymerization. The photo-mediated polymerization could use the handheld UV light as the l

First, we compared the four species of mangroves in Taiwan, Kandelia candel Druce, Rhizophora stylosa Griff, Avicennia marina Vierh and Lumnitzera racemosa Willd, inoculated by endomycorrhizae in no contaminated soils. According to the experimental results, the four species of mangroves could be colonized by Glomus aggregatum and Glomus mosseae. In colonization rate and colonization intensity, Glomus aggregatum were found highe

Abstract:

碩士<br>國立陽明大學<br>醫學生物技術研究所<br>87<br>Abstract Benzo(a)pyrene( B(a)P ) is a kind of environmental pollutants that commonly exists in our circumstance. It has been shown that B(a)P is carcinogenic in many researches of genotoxicities and experimental animals , but the underlying mechanism is still not clear. To surmise the possible molecular mechanisms, we studied the effects of B(a)P on the molecules in cytoplasm ( protein kinase C ) and nucleus ( proto-oncogene : c-jun , c-fos ) , individually , and B(a)P's transformation ability by performing doubling time , saturation density , tran
