Detection method of wormlike micelles

A detection method of wormlike micelles, wherein the detection method, comprising a step of providing a z-ArN2+ long-chain probe and a z-ArN2+ short-chain probe, and the z-ArN2+ long-chain probe and the z-ArN2+ short-chain probe have a structure shown in Formula I:

• in the z-ArN2+ short-chain probe, z=1, and R is —CH3;
• and in the z-ArN2+ long-chain probe, z=16, and R is —C16H33;
• the method further comprising the following steps:
• (1) preparing the long-chain probe into an acetonitrile stock solution with a concentration of 0.005 M to 0.05 M, and preparing the short-chain probe into an acetonitrile stock solution with a concentration of 0.05 M to 0.5 M;
• (2) adding a surfactant to a volumetric flask, dissolving and diluting with a diluent, and adding the stock solution of the long-chain probe obtained in step (1) to obtain a test solution;
• wherein the test solution has 5×10−4 M to 5×10−5 M of the long-chain probe and 1×10−3 M to 2 M of the surfactant by concentration;
• wherein in step (2), the surfactant is cetyltrimethylammonium bromide (CTAB);
• (3) replacing the surfactant in step (2) with an ammonium salt or a sulfonate, dissolving and diluting with the diluent, and adding the stock solution of the short-chain probe obtained in step (1) to obtain a control solution;
• wherein the control solution has 5×10−3 M to 5×10−4 M of the short-chain probe by concentration;
• (4) conducting a reaction on the test solution obtained in step (2) at 25° C. to 60° C. for 5 h to 48 h under sealing in the dark, diluting an obtained reaction product with the diluent, and measuring a yield of the product by high-performance liquid chromatography (HPLC);
• (5) repeating the operations of step (4) on the control solution obtained in step (3);
• and
• (6) obtaining the yield of the product measured by the HPLC from an average of peak areas of three or more repeated injections and calibration curves of cetyldimethylphenol and cetyldimethylbromobenzene.
