Abstract:
The overall aim of this project was to investigate the synthesis and activity of a range of compounds based on the benzo[b]thiophene-2-carboxamide structural motif as potential new antimalarial agents, and to a lesser extent as antibacterial agents.In order to subsequently explore any structure-biological activity relationships, the first part of the project involved the systematic synthesis of some 39 non-fused substituted benzo[b]thiophene amide derivatives including tetrahydroisoquinolines, tetrahydro-β-carbolines, dihydropyrroles, piperazines, piperidines and other bridged ring systems as

Cell surface saccharides are involved in a variety of essential biological events. Fluorescent sensors for saccharides can be used for detection, diagnosis, analysis and monitoring of pathological processes. The boronic acid functional group is known to bind strongly and reversibly to compounds with diol groups, which are commonly found on saccharides. Sensors that have been developed for the purpose of saccharide recognition have shown great potential. However, they are very hydrophobic and this lack of essential water-solubility makes them useful in biological applications. The first section

In addition, two alkoxy groups were added to aromatic ring to gain additional liquid crystal phase and increase solubility. The obtained C12-PTTT compound was used to fabricate organic field effect transistor (OFET) devices. For the OFET device with self-assembled monolayers, its mobility increases from 6.14 × 10-4 cm2V-1s-1 to 2.44 × 10-3 cm2V-1s-1. Besides the traditional spin coa

The Crystal structure of diTT-BST (1) shows that the S-S interaction between the thiophene-S and alkyl chain-S are the dominant stabilizing force governing the packing of the molecules. These materials were designed to study the effect of extended conjugation on the photochemical, photophysical, and electrochemical properties.
