A nonintuitive observation of monovalent anion-induced ion current rectification inversion at polyimidazolium brush (PimB)-modified nanopipettes is presented. The rectification inversion degree is strongly dependent on the concentration and species of monovalent anions. For chaotropic anions (for example, ClO4?), the rectification inversion is easily observed at a low concentration (5 mm), while there is no rectification inversion observed for kosmotropic anions (Cl?) even at a high concentration (1 m). Moreover, at the specific concentration (for example, 10 mm), the variation of rectification ratio on the type of anions is ranged by Hofmeister series (Cl?≥NO3?>BF4?>ClO4?>PF6?>Tf2N?). Estimation of the electrokinetic charge density (σek) demonstrates that rectification inversion originates from the charge inversion owing to the over-adsorption of chaotropic monovalent anion. To qualitatively understand this phenomenon, a concentration-dependent adsorption mechanism is proposed.

The invention discloses a method for preparing a chiral amino acid tetrazole compound. The method is characterized by synthesizing and preparing the chiral amino acid tetrazole compound by taking cyanophenylalanine and sodium azide as raw materials, dimethyl formamide as a solvent and imidazole polymer ferric salt ionic liquid as a catalyst, and specifically comprises the following steps: mixing the cyanophenylalanine, the sodium azide, the imidazole polymer ferric salt ionic liquid and the dimethyl formamide which are in proportional amounts, heating to 110 to 130 DEG C while stirring, reacting for 20 to 30 hours at a constant temperature, cooling to room temperature, filtering and separating an imidazole polymer ferric salt ionic liquid catalyst, regulating pH (Potential of Hydrogen) ofa separating solution to be neutral with hydrochloric acid, adding an ethyl acetate for extracting and separating liquid, taking a supernatant organic phase, rotationally drying an organic solvent after washing, obtaining white solid, and carrying out vacuum drying, thus obtaining the chiral amino acid tetrazole compound.
