Colorimetric chemosensor for ATP based on phthalimide-appended poly(2,5-dimethoxyaniline)

An overview on the development of different optical sensing platforms for adenosine triphosphate (ATP) recognition

“…41) for the selective recognition of ATP. 130 This chemosensor was composed of a conjugated polymer poly(2,5-dimethoxyaniline) having phthalimide (PDMAp), which can form hydrogen bonds with the adenine moiety of ATP. 91 was synthesized via oxidative polymerization with 10-camphorsulfonic acid (CSA) and 2,3-dicholoro-5,6-dicyano-1,4-benzoquinone (DDQ) and dedoping with an aqueous ammonia solution.…”

“…The absorption spectral change can be attributed to the doping process of ATP on 91 through hydrogen bonds between phthalimide and adenine as well as electrostatic interactions between the phosphate group of the ATP and the backbone of 91. 130 Kataev and co-workers developed the anthracene-and coumarin-derived ligands 92 and 93 (Fig. 42), with 2(amino-…”

Colorimetric sensing of H2PO4− using a Pb2+ complex of a pyridylazo dye in aqueous solution

“…Optical chemosensors for the sensitive and selective detection of environmentally and biologically relevant anions have attracted considerable interest in various clinical, biological, and environmental fields. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Among biologically functional anions, phosphates are of great significance because of their vital roles in biological processes such as gene regulation, energy storage, and cellular signalling. [15][16][17] Phosphates are also essential components of lipid phosphate, nucleic acid polymers DNA and RNA, high-energy phosphate compounds adenosine triphosphate (ATP), teeth, and bone matrix.…”

A Novel Turn‐on Fluorescent Probe for Highly Selective Detection of Phosphate Ion in Living Cell

“…[10][11][12][13][14][15] PPi and ATP, both generate two molecules of inorganic phosphate by hydrolysis under cellular conditions. [16][17][18] Although there are many chemosensors for selective recognition of PPi [19][20][21][22] and ATP, [23][24][25][26] it is still difficult to predict whether a chemosensor can only recognize Pi because of the selectivity of Pi is hindered by the presence of structurally similar anions in cells. Additionally, 2-(2-hydroxyphenyl)benzothiazole (HBT) is a fluorophore with significant photostability and reasonable fluorescent quantum yield.…”
