Method for preparing mercapto-ammonium ligands and their use in the functionalization of the surface of metal nanoparticles and a method for functionalizing the surface of metal nanoparticles, especially gold
the subject of the invention is a manufacturing amoniowo - merkaptanowych ligands of general formula: h3n + - ch2 - (ch2) n - ch2 - sh, in which n is the number of complete from 1 to 7, preferably n is 2, intended for use in funkcjonalizacji surface of metals, preferably gold.how is it that includes the following steps, where (a)? ,? - dibromopochodnu0105 alkilowu0105 undergo reaction with ftalimidkiem potassium in the presence of acetonitrile below boiling point organic solvent, in the temperature range from 105 to 82u00b0c, with development? - bromoalkilowej ftalimidu derivative.subsequently, (b) obtained in the previous stage. - bromoalkilowu0105 ftalimidu derivative is mixed with potassium tiooctanem in acetone at room temperature, with the development of product in the form of tioestru n - alkiloftalimidu.then (c) obtained in the previous stage tioester n - alkiloftalimidu undergo reaction hydrazynolizy with development product, which is then hydrolysed in the presence of a strong inorganic acid, to produce the final product in the form of amoniowo - merkaptanowego ligandu.the invention also includes the use amoniowo - merkaptanowych ligands, to funkcjonalizacji surface metal nanoparticles, especially gold way funkcjonalizacji surface metal nanoparticles, especially gold and funkcjonalizacji surface of metal nanoparticles, especially gold and their self organisation in liquid / liquid interface.
