A novel fluorescence ratiometric pH sensor based on covalently immobilized piperazinyl-1,8-napthalimide and benzothioxanthene

Synthesis and photophysical behaviors of a blue fluorescent copolymer as chemosensor for protons and Ni2+ ion in aqueous solution

“…Yield: 43%, mp: 104-106°C. 1 A mixture solution of 1.0 g (7.0 mmol) AM and 8.0 mg (0.05 mmol) of AIBN in dry THF (10 ml) was introduced into a dry polymerization tube. The solution was deoxygenated by purging with purified N 2 gas.…”

“…Highly sensitive and selective molecular sensory materials have received considerable attention in recent years [1][2][3]. Many attempts at the design and construction of chemosensors using optical changes as output signals have been reported [4].…”

A Fluorescent pH Chemosensor Based on Functionalized Naphthalimide in Aqueous Solution

“…And some of them have been used as fluorescent chemosensors for metal cations, [14][15][16][17] anions 18,19 and pH [20][21][22][23] in recent years. These make naphthalimide derivatives potential carriers for preparation of new optical chemosensors.…”

Syntheses and pH Sensing Applications of Imine-Coupled Phenol and Polyphenol Species Derived from 2-Amino-4-Nitrophenol

“…New kinds of optical sensors have attracted great attention of researchers due to their possible applications in industrial, environmental, and medicinal areas [6,7]. Several kinds of optical pH and ion sensors have been published so far [8][9][10][11][12][13]. Optical sensors have a lot of advantages including cheapness, fine sensitivity, freedom from electrical interference, safety, and being easy to apply [14].…”
