Spectral study and antifouling assessment of some thiosemicarbazone derivatives

Three thiosemicarbazone derivatives were synthesised: p-chlorobenzylideneamino thiosemicarbazone, p-itrobenzylideneamino thiosemicarbazone and p-N,N'-dimethylminobenzylideneamino thiosemicarbazone. The structures of these compounds were characterised by elemental analysis, IR, H-1 NMR and UV spectral measurements. The antifouling properties of the compounds were evaluated through the incorporation of each compound in a marine coating system and testing the system in Alexandria Eastern Harbour water. The results are discussed in the light of the leaching rate of the compounds from their paint films, and their interaction with paint matrix.
