Abstract:

Covalent Organic Frameworks (COFs) are a novel class of highly stable, purely organic crystalline frameworks made of molecular building blocks. For example, the condensation of boronic acids with appropriate polyols in principle allows the design of precisely controllable structures since their chemical and physical properties can be easily tuned through the selection of the building blocks. The young research field of COFs has attracted scientists due to their extraordinary and versatile properties, however, strategies to control the topology and the properties of the backbone as well as the

Abstract:

The two main subjects of this thesis are the realization of supramolecular self-assembled monolayers at surfaces and the formation of surface-supported two-dimensional covalent organic frameworks. Both topics, albeit different, yield long-range ordered open-pore networks with quite different stabilities, depending on the strength and type of bonds holding them together. The surface of choice is mainly graphite, which is considered an inert substrate. Graphite yields pristine clean, very large and flat surfaces when cleaved, facilitating the observation in real space of the molecular networks a

Abstract:

There is an increasing necessity for the pharmaceutical industry to develop enantiomerically pure drugs. Up till now, production of enantiomerically pure molecules has been provided by harvesting them from plants or utilising homogeneous catalysis and biocatalysis. None of these methods are efficient means of production, and attention is now being directed towards heterogeneous enantioselective catalysis as the preferred technique. This is on account of the high product yield and ease of separation of catalyst from the reaction mixture. Over the past few decades, a great deal of research has b

Abstract:

π-Conjugated two-dimensional covalent organic frameworks (2D COFs) are emerging as a novel class of electro-active materials for (opto-)electronic and chemiresistive sensing applications. However, understanding the intricate interplay between chemistry, structure and conductivity in π-conjugated 2D COFs remains elusive. Here, we report a detailed charac-terization for the electronic properties of two novel samples consisting of Zn- and Cu-phthalocyanine-based pyrazine-linked 2D COFs. These 2D COFs are synthesized by condensation of metal-phthalocyanine (M=Zn and Cu) and pyrene derivatives. The

First, Covalent benzoxazine framework (CBF-1) was synthesized via a solvothermal method using trifunctional aminophenyl triazine (TAPT), and trifunctional hydroxyphenyl triazine (THPT) paraformaldehyde through Mannich condensation reaction. This new CBF-1 underwent thermal cross-linked curing to generate a highly cross-linked CBF (CCBF-1), which, with ca

Abstract:

碩士<br>國立中山大學<br>材料與光電科學學系研究所<br>106<br>In this study, we synthesized a series of related monomers and polymers based on covalent organic frameworks (COFs) materials. In the first place, we prepared different five monomer derivatives, including TPA-3NH2, TPT-3NH2, TPA-3CHO, TPP-3CHO, and TPT-3CHO, which were characterized by Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopies. Secondly, we used the condensation polymerization to synthesize six different COFs via the Schiff base reaction to possess various two-dimensional crosslink structures, named TPA-TPA-COF
