Polythiophene based fluorescence sensors for acids and metal ions

Synthesis and characterization of electrically conducting copolymers based on biphenyl and thiophene

“…1,2 CPs are used in areas such as rechargeable batteries, [3][4][5] electroluminescent polymer displays, 3 polymer light-emitting diodes, [3][4][5] flexible ''plastic'' transistors, 3 sensors, 4,6,7 and photovoltaic cells. 4,5 CPs can be synthesized by chemical polymerization or by electropolymerization, whereas the latter offers several advantageous features, 1,3,5 such as absence of catalyst, direct formation of the doped polymer film on the electrode surface, easy control of the film thickness and the possibility of performing in situ characterization of the deposited film by electrochemical and other techniques.…”

Functionalized polythiophenes: Recognition materials for chemosensors and biosensors of superior sensitivity, selectivity, and detectability

“…Other than those used for the metal cation sensing, different derivatives of thiophene were used for fluorescence sensing of protons [61][62][63]. In one study, self-assembled monolayers (SAMs) of pyridine and triethoxysilane terminated oligothiophene derivatives and triethoxysilane deposited on a quartz slide were used as the fluorescence chemosensor for solution acidity (Scheme 7) [61].…”

A new polythiophene derivative-based fluorescent sensor for Co2+, Cu2+, Cd2+, and its complex with Cu2+ for sensing homocysteine and glutathione

“…John J. Lavigne et al realized multidimensional response analysis toward identification of a series of divalent metal ions, while the whole detection relied on small molecules which acted as competing ligands, making it uneasy to handle [23]. Swapan Kumar Dolui et al prepared a polythiophene based fluorescence sensor for acids and metal ions [24]. The investigation was totally carried out in THF, also, discrimination of the metal ion complexation was unsatisfactory.…”
