Synthesis of two novel fluorescein appended dipyromethanes (DPMs): Naked-eye chemosensors for fluoride, acetate and phosphate anions

Evaluation of naked-eye sensing and anion binding studies in meso-fluorescein substituted one-walled calix[4]pyrrole (C4P)

“…This is because of their simple-synthetic procedures, besides they also have an appropriate cavity as well as conformational exibility. [51][52][53][54][55][56][57] Remarkably, since the Sessler's research group, investigated the anion binding study for the rst time of the parent C4P system in 1996, 58 this versatile receptor rekindled pervasive interest of the researchers worldwide, as it has several possible positions (e.g. meso-, b-pyrrolic positions, & NH sites) to functionalize with ease.…”

Facile synthesis and anion binding studies of fluorescein/benzo-12-crown-4 ether based bis-dipyrromethane (DPM) receptors

“…[11][12][13][14][15][16][17][18][19] But, we believe that, there is still a pressing necessity to develop simpleto-make yet highly sensitive and selective anion receptors. [20][21][22][23][24][25][26][27][28][29][30] Gratifyingly, preorganization leads to the selective as well as effective binding between the specic receptor and analyte(s). Moreover, it also upturns the rigidity, which usually hinders the entree of analyte towards the binding site(s).…”
