Three new chromogenic receptors have been synthesized with the primary objective of facilitating the selective recognition of PO43−and CO32− ions in an organo‐aqueous medium. R1 and R2 exhibit an extraordinary detection limit aligning with both EPA and WHO guidelines. R1 shows LOD of 0.135 ppm for PO43− and 0.175 ppm for CO32−, while R2 sets forth a LOD of 0.427 ppm for PO43− and 0.729 ppm for CO32−. The binding mechanism involves intramolecular charge transfer (ICT) band are substantiated by comprehensive studies that include UV‐Vis titration, 1H‐NMR titration, DFT studies and electrochemical studies. Chemosensors were employed in the formulation of logic gate, the fabrication of a paper strip test kit and its application in RGB color sensor device.

BTDs (2,1,3-benzothiadiazoles) are fluorescent heterocycles widely used in different applications, including biomarkers, sensing optical devices, OLEDs, organic transistors, and solar cells. This review mainly focuses on the current progress in the design of compounds derived from the BTD core, aiming for their use as chromogenic and/or fluorogenic devices for detecting anionic, cationic, and neutral analytes. Reactions and synthetic strategies that show the synthetic versatility of BTDs are initially presented, to provide a better understanding regarding the assembly of optical detection systems. The photophysical mechanisms of the detection are also described. A discussion is also presented on the target analytes for which the optical detection devices based on BTD were planned. The examples discussed here will offer the sensors community perspectives for developing new optical detection devices based on BTD for different types of analytes of importance for the most diverse areas of knowledge.

Currently, analyzing pharmaceuticals and biomarkers is crucial for ensuring medication safety and protecting life and health, and there is an urgent need to develop new and efficient analytical techniques in view of the limitations of traditional analytical methods. Molecularly imprinted ratiometric fluorescent (MI-RFL) sensors have received increasing attention in the field of analytical detection due to their high selectivity, sensitivity and anti-interference ability, short response time, and visualization. This review summarizes the recent advances of MI-RFL sensors in the field of pharmaceuticals and biomarkers detection. Firstly, the fluorescence sources and working mechanisms of MI-RFL sensors are briefly introduced. On this basis, new techniques and strategies for preparing molecularly imprinted polymers, such as dummy template imprinting, nanoimprinting, multi-template imprinting, and stimulus-responsive imprinting strategies, are presented. Then, dual- and triple-emission types of fluorescent sensors are introduced. Subsequently, specific applications of MI-RFL sensors in pharmaceutical analysis and biomarkers detection are highlighted. In addition, innovative applications of MI-RFL sensors in point-of-care testing are discussed in-depth. Finally, the challenges of MI-RFL sensors for analysis of pharmaceuticals and biomarkers are proposed, and the research outlook and development trends of MI-RFL sensors are prospected.
