Synthesis, photodynamic activity and supramolecular chemistry of unsymmetrical and side-strapped phthalocyanines. / CUHK electronic theses & dissertations collection

January 2007 (has links)
Chapter 1 presents an overview of the synthetic methods and properties of phthalocyanines, focusing on the unsymmetrical analogues, side-strapped derivatives, and crown ether-containing phthalocyanines. The use of these compounds in photodynamic therapy and their supramolecular chemistry are also reviewed. / Chapter 2 reports the synthesis of a series of unsymmetrical "3+1" zinc(II) phthalocyanines via a one-pot cyclization-transesterification procedure in different alcoholic solvents. Their photophysical properties and in vitro photodynamic activities toward HT29 human colorectal adenocarcinoma cells and HepG2 human hepatocarcinoma cells are also reported. One of the compounds, a zinc(II) phthalocyanine substituted with two polyethylene glycol chains, can form surfactant-free nanoparticles in water and in the culture media. These phthalocyanine-containing nanoparticles exhibit a high photocytotoxicity toward HepG2 cells showing that the polymeric substituents may serve as an effective carrier system. / Chapter 4 reports the synthesis and spectroscopic properties of a side-strapped bis(17-crown-5)-containing zinc(II) phthalocyanine. In contrast to the previously reported benzo-fused crown ether-appended phthalocyanines, the ether rings of this molecule are orthogonal to the phthalocyanine plane. As a result, this compound forms J-aggregate in chloroform. Upon addition of alkali metal ions, these aggregates are disrupted forming a linear supramolecular structure, which has been inferred by absorption and fluorescence spectroscopic methods. / Chapter 5 describes the synthesis and spectroscopic properties of two side-strapped zinc(II) phthalocyanines, which have one and two benzo-25-crown-8 moieties, respectively. The bis(crown ether) analogue favors the formation of J-aggregate in non-coordinating solvents. In CHCl 3, the aggregation of these compounds is promoted by the addition of 1,2-bis(pyridinium)ethane bis(hexfluorophosphate). The aggregation of these compounds can also be induced by the oxonium ions generated by the addition of organic acids such as trifluoroacetic acid and acetic acid. After neutralization with Et3N, the aggregate is disrupted and the phthalocyanines are converted back to their original nonaggregated state. For the symmetrically substituted compound, this acid-base switched aggregation-disaggregation process can be recycled for more than 8 times. / The synthesis, spectroscopic characterization, photophysical properties, aggregation properties, and in vitro photodynamic activities of several side-strapped phthalocyanines are described in Chapter 3. Pentaerythritol, having four hydroxyl groups, has been used as the linker to connect hydrophilic oligoethylene glycol chains or hydrophobic alkyl chains to the phthalocyanine core. The aggregation tendency of these compounds, which depends on their amphiphility, has been studied by absorption spectroscopy. The relationship of this property with the in vitro photocytotoxicity has also been revealed. / This thesis reports our studies on several novel series of phthalocyanines including a series of "3+1" unsymmetrical phthalocyanines formed by a one-pot cyclization-transesterification procedure, and several side-strapped phthalocyanines having an amphiphilic character or containing crown ether units. The applications of these compounds in photodynamic therapy and supramolecular chemistry have also been explored. / by Bai, Ming. / "September 2007." / Source: Dissertation Abstracts International, Volume: 69-08, Section: B, page: 4745. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references. / Electronic reproduction.

Synthesis, photophysical properties, and in vitro photodynamic activities of new silicon(IV) phthalocyanines. / CUHK electronic theses & dissertations collection

January 2005 (has links)
A novel series of silicon(IV) phthalocyanines substituted axially with one or two 1,3-bis(dimethylamino)-2-propoxy group(s) are described in Chapter 3. These compounds are essentially non-aggregated in common organic solvents and show a weak fluorescence emission, while their methylated derivatives are also non-aggregated even in aqueous media and exhibit a strong fluorescence emission. The photocytotoxicities of these compounds against HepG2 and J774 cells have also been investigated. These new phthalocyanines, in particular the unsymmetrical and amphiphilic analogues, are highly potent with IC50 values down to 20 nM. The cellular uptake and subcellular localisation of these compounds have also been studied by fluorescence microscopy. The unsymmetric phthalocyanine SiPc[OC3H5(NMe2 )2](OMe) has a high and selective affinity to the mitochondria of HepG2 cells. / Chapter 1 presents an overview of photodynamic therapy, including its historical development, current clinical status, and photophysical and biological mechanisms. Some representative photosensitisers are also reviewed. / Chapter 2 describes two silicon(IV) phthalocyanines containing poly(ethylene glycol) chains at the axial positions, including their synthesis, spectroscopic characteristics and photophysical properties. Their complexation with bovine serum albumin and in vitro photodynamic activities towards HepG2 human hepatocarcinoma cells and J774 mouse macrophage are also reported. / Chapter 4 discusses the photodynamic effects of a series of silicon(IV) phthalocyanines with different axial substituents against HT29 and T84 human colon adenocarcinoma cells, with the long-term goal of developing efficient photosensitising agents for colorectal cancer. While these compounds are not cytotoxic in the absence of light, they exhibit high photocytotoxicities with IC50 values as low as 17 nM. / Chapter 5 reports the synthesis and characterisation of a series of halogenated silicon(IV) phthalocyanines substituted axially with poly(ethylene glycol), 1,3-bis(dimethylamino)-2-propoxy or isopropylidene-protected galactose groups, with the goal of enhancing the photosensitising properties by heavy atom effect. (Abstract shortened by UMI.) / This thesis describes the synthesis, spectroscopic characterisation, and photo-physical and biological properties of a series of novel silicon(IV) phthalocyanines which are potentially useful as second-generation photosensitisers for photodynamic therapy. / Lo Pui-chi. / "September 2005." / Adviser: Dennis K.
