“…The preparation of these sensors is a daunting task that either requires multiple postsynthetic modifications or a challenging preparation of the chiral monomers. Nonetheless, the alternatives are few and are based on biological macromolecules that pose additional challenges in handling, storing, and utilization . For these reasons, COFs are possibly some of the most promising types of enantiomeric sensors currently available.…”

Following the advancements and diversification in synthetic strategies for porous covalent materials in the literature, the materials science community started to investigate the performance of covalent organic polymers (COPs) and covalent organic frameworks (COFs) in applications that require large surface areas for interaction with other molecules, chemical stability, and insolubility. Sensorics is an area where COPs and COFs have demonstrated immense potential and achieved high levels of sensitivity and selectivity on account of their tunable structures. In this review, we focus on those covalent polymeric systems that use fluorescence spectroscopy as a method of detection. After briefly reviewing the physical basis of fluorescencebased sensors, we delve into various kinds of analytes that have been explored with COPs and COFs, namely, heavy metal ions, explosives, biological molecules, amines, pH, volatile organic compounds and solvents, iodine, enantiomers, gases, and anions. Throughout this work, we discuss the mechanisms involved in each sensing application and aim to quantify the potency of the discussed sensors by providing limits of detection and quenching constants when available. This review concludes with a summary of the surveyed literature and raises a few concerns that should be addressed in the future development of COP and COF fluorescencebased sensors.

“…Similar results have been reported in previous articles to detect numerous toxic chemicals and biochemicals applying the I-V approach. [34][35][36][37][38][39][40][41] To establish the calibration of 1,2-DAB sensor, the current data shown in Fig. 5(b) were isolated at the potential of +1.5 V, and a new calibration curve is plotted from the linear relation of the current versus concentration of 1,2-DAB, as shown in Fig.…”

“…Chiral analysis and enantiodiscrimination at an electrode [7] or other detection surfaces (e. g. electronic devices) have been discussed in detail in the following reviews ( Figure 1). [4,5,[8][9][10] As far as electrochemical chiral detectors are concerned, the original applications targeted the use of ion-selective electrodes with a chiral selector, which was added into the electrode membrane. This way, stereoisomers of mandelic acid, nitrophenylethylamine or carnitine, and many other molecules can be distinguished potentiometrically.…”

Chirality is a fascinating phenomenon for recent electrochemistry and materials research, allowing for the preparation of detection platforms based on analyte enantiodiscrimination and the development of advanced chiroptical devices and chiral electrodes. In this Viewpoint, we highlight new directions in the field of chiral helical polyaromatic molecules (mainly helicenes) that are useful for the preparation of optically and redox-active polymers and/or self-assembled thin layers, nanostructures and functional electrode surfaces. Instead of the previously reported chiral materials prepared by molecular imprinting, a concept based on the preparation of inherently chiral helicene-based materials with (opto)electrochemical applicability is presented. A short overview of well-established electrochemical methods for the research of chiral molecules is also outlined.
