Triphenyl radical

WebThe new mixed-halide triphenyl methyl radicals represent a powerful building block for customized design and synthesis of stable luminescent radicals. Introduction WebThe most common forms of triphenyl methyl used are malachite green and basic violet. Malachite green has been commonly used as ectoparasiticide and fungicide in fish farming since 1936. In Africa, it has been employed against the infection of protozoans, nematodes, bacteria, cestodes, crustaceans, etc. ( Srivastava, Sinha, & Roy, 2004 ).
