Recent Development of Anion Selective Fluorescent Chemosensors

First phenalenone based receptor for selective iodide ion sensing

“…Keeping these factors in mind a 9 M THF solution of 4 was titrated with TBAI. Since little or no changes were observed in absorption or emission experiments (see supplementary data S8), it is highly indicative that the selective encapsulation of I − is not dependent on basicity rather on compatible core size of the pseudocavity furnished by three flexible pods of receptor 3 [43]. The notion of N H interaction was further eliminated in the present case by NMR experiments.…”

Covalent Interactions in Chemosensor Design

“…Among all the covalent functional group interactions, boronic acid stands out as the most commonly used in chemosensor construction because of its strong interactions with diols [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], aminoalcohols [20][21][22], α-amino acids [23], α-hydroxyl acids [24][25][26][27], alcohols [15,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], as well as cyanide [45,46] and fluoride [47][48][49]…”

Reaction‐based probe for hydrogen sulfite: dual‐channel and good ratiometric response

“…In recent decades, efficient detection for anions has attracted considerable attention because of their importance in a large number of biological processes (1)(2)(3)(4)(5)(6). Among these anions, hydrogen sulfite has been widely used as a preservative for foods, beverages and pharmaceutical products (fish, potatoes, wine, etc.).…”
