“…Compound 25,26,27,arene (1) 26 was employed to prepare an azocalix [4]arene derivative with four carboxyl groups, 5,11,17,23-tetrakis[(p-carboxyphenyl)azo]-25, 26,27,28-tetrahydroxycalix [4]arene (2). 27 However, its crystal structure has not been determined yet and its pH sensing properties are virtually unknown.…”

“…[4][5][6][7] As a good chemosensor, it should exhibit an appropriate, rapid and reversible response towards H ＋ in a wide pH range and should not affect the ongoing measurement. So far, a number of pH sensing compounds have been synthesized, [8][9][10][11][12][13][14][15][16][17][18] some of which showed potential application as the pH probes.…”

Treatment of 5,11,17,23-tetrakis[(p-carboxyphenyl) X-ray analysis of 2•4DMF revealed that its calix[4]arene core adopts a flattened cone conformation in which opposed phenyl groups take parallel or sharply inclined positions. The intra-and intermolecular hydrogen-bonding interactions and the π…π interactions form a 2D hydrogen-bonded wavelike network. Compound 2 had a unique reversible color change in a wide pH range from 1 to 13.5 and showed interesting pH sensing properties.

“…For instance, the generatorcollector operation mode has been exploited in the study of the diffusion of electroactive species within a thin film deposited onto the surface of microelectrodes arrays [99][100][101][102]. The modification of interdigitated microelectrodes with conducting polymers allowed the preparation of new miniaturized pH electrochemical sensors [103][104][105][106]. Other microelectrodes arrays modified with inorganic films [107], organic polymers [108], inorganic-organic composite materials [109], and enzymes [110] were recently reported.…”

There is a growing demand for continuous, fast, selective, and sensitive monitoring of key analytes and parameters in the control of diseases and health monitoring, foods quality and safety, and quality of the environment. Sensors based on electrochemical transducers represent very promising tools in this context. Conducting polymers (CPs) have drawn considerable interest in recent years because of their potential applications in different fields such as in sensors, electrochemical displays, and in catalysis. Among the organic conducting polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives have attracted particular interest due to their high stability and high conductivity. This paper summarizes mainly the recent developments in the use of PEDOTbased composite materials in electrochemical sensors.
