This invention is related to preparation of photosensitive ruthenium based aminoacid monomers and oligomers, aminoacid monomer-protein cross- linking using photo sensitat ion and conjugation on micro and nano-structures by ruthenium-chelate based monomers. Its vast range biotechnolgy applications of multifunctional, biocompatible, stabilE and specific micro and nanobio-conjugates, which will stand-alone or simultaneously enable (i) both purification and determination, (ii) both targeting and imaging and theranostics and (iii) catalysis and determination. The construction and method of preparation is applicable to silica materials, superparamagnetic particles, QDs, CNTs, Ag/ Au nanoparticles and Au surfaces and polymeric materials. The photosensitive aminoacid monomer linkers can react via chemically and biocompatible to a lot of different micro and nano-surface and then to the protein when they act as a single-step cross-linking reaction using irradiation. The photosensitive conjugation based on click biochemistry can be carried out at mild conditions, independent of pH and temperature, without affecting conformation and function of protein.

Regioselective addition of thiophenol to α,β-unsaturated N-acylbenzotriazoles has been achieved by controlling the conditions. Thus, three types of products, namely α,β-unsaturated thioesters, β-thiophenoxy substituted N-acylbenzotriazoles, and β-thiophenoxy substituted thioesters were selectively obtained in good to excellent yields.

triethylamine, α,β-unsaturated N-acylbenzotriazoles reacted with amino compounds in a variety of ways. Thus, N-cinnamoylbenzotriazoles reacting with aromatic amines afforded novel addition products β-benzotriazolyl amides 3, which might be normally formed from the alternative but unknown 1,4-addition of benzotriazole to N-cinnamoylamides. The type 3 compounds could also result from the reaction between
