The potential use of electron-deficient heterocyclic azo compounds as inkjet dyes was explored. 2-Nitrosopyridine could be used to form a series of azo compounds via the Mills’ reaction with electron-rich aromatic amines. Conditions for this process were optimised by varying solvent and pH. In the presence of ethers, 2-nitrosopyridine is quickly reduced to azoxypyridine. This reaction follows first order kinetics; diethyl and diisopropyl ether react at similar rates, whereas cyclic ethers such as THF are far slower. Organic bases such as Hunigs base were also found to promote formation of azoxypyridine. The mechanism of this reduction was studied. The electrochemistry of 2-nitrosopyridine and azoxypyridine was also explored. Using the optimised conditions for the Mills’ reaction, 2-nitrosopyridine not only reacts with electron-rich amines but also electron-deficient examples. The series was also expanded to include other heterocycles as well as pyridine via the corresponding heterocyclic nitroso compound. Other nitroso compounds prepared were 1- nitrosoisoquinoline, 2-nitrosopyrazine, 4-nitrosopyrimidine and 2-nitrosopyrimidine. The absorption maxima of azo compounds prepared from these precursors were found to correlate with the values for the corresponding azobenzenes. 2-Nitrosopyridine and 2-nitrosopyrimidine react with diamines to give monoazo products. These in turn could be diazotised and coupled with various components to give either bisazo or trisazo compounds. These dyes were tested for their ozone and light fastness properties. The bisazo examples were found to have good ozone fastness but poor light fastness. The pyrimidine examples only showed a slight improvement in ozone and light fastness compared to their pyridine analogue. 2,3-Phthalocyanines are important components in cyan dyes. New routes to precursors of these compounds were explored using flash vacuum pyrolysis (FVP).

The aim of this project is to find the optimum growth conditions for growing amorphous Zn1-x-yAlxSny (x=0.02 and 0.2) films with various dopents and high transmittance in visible range. By varying substrate temperatures, working pressures, RF powers and growth modes, amorphous Zn1-x-yAlxSny films with high transmittance were successfully grown at low and room temperatures. Grazing-incident small-angle X-ray diffraction data indicates that low temperature, high working pressure, low RF power and the short deposition period are the key for growing amorphous films in which adatoms on the surface of substrate do not have enough energy for migration and constructing a better crystal structure. As a result of this inadequate energy of adatoms, clusters of grains can be observed on the surface of films by the atomic force microscope. Amorphous Zn1-x-yAlxSny films possess crystalline short range order that opens up the optical and electronic bandgap. In terms of transmittance, a blue shift in the critical transmittance and a higher transmittance in IR range are observed. The high level doping of Al and Sn in ZnO films introduces crystal disordering in films and results in amorphous films even they were grown at room temperature. X-ray absorption near edge spectrum (XANES) discovers that the doped Sn behaves as tetra-valence ions for those Zn1-x-yAlxSny films with high oxygen deficiency. All amorphous films grown in this project exhibits a very low conductivity.

Polyamide containing groove binding agents have been widely reported We now synthesized netropsin analogs containing azo¡Bimine and diimine functional groups in place of the amide functionality and study their biological activities. Some of these analogs were found to have cytotoxicity in the range of 5 g/mL.
