Supramolecular optical sensor arrays for on-site analytical devices

Selectivec-MYCG4 DNA recognition based on a fluorescent light-up probe with disaggregation-induced emission characteristics

“…Fluorescence detection systems based on supramolecular chemistry have attracted the attention of scientists and experienced rapid development, offering functional materials that possess advanced performances and functions toward sensitively and selectively monitoring the target analytes. 24,25 BODIPY-based compounds are considered archetypal dyes with excellent photophysical and biological properties along with the tendency to form well-defined supramolecular architectures. 26 However, most of these dyes exhibit partial or complete suppression of fluorescence in aqueous solutions because of aggregation-caused quenching (ACQ), which often limits their practical applications.…”

Revisiting -dicyanovinyl substituted calix[4]pyrrole : toward the chemodosimetric detection of hydrazine in solution

“…Analytical methods utilizing optical signatures and supramolecular sensors/receptors have been of great interest to the scientific community in recent years. 14,15 Among the diverse supramolecular receptors available, the tetrapyrollic macrocyclic receptor known as calix [4]pyrrole (C4P) has shown a promising role in the recognition of diverse analytes 16 . C4P possess a built-in recognition site able to recognize anions or polar guests, while its functionalization at the level of meso-carbon or pyrrole allow to achieve cation or ion-pair recognition throught non-covalent interactions.…”

Supramolecular Polymers with Photoswitchable Multistate Fluorescence for Anti-Counterfeiting and Encryption

“…Supramolecular polymers have been extensively used to construct SFMs for various applications, such as displays, sensors, and information encryption, due to their excellent reversibility and sensitive responsiveness to external stimuli. − Moreover, abundant supramolecular interactions, including host–guest interactions, ligand–metal complexations, π–π stacking, ionic interactions, and hydrogen bonding (H-bonding), can not only offer flexibility for optical performance regulation but also possess excellent self-assembly ability and potential self-healing capacity. − Therefore, supramolecular polymers may serve as an ideal material platform for the construction of novel PMFS with more comprehensive properties. However, the feasibility of using supramolecular polymers and fluorescent photochromism to construct photoswitchable multistate fluorescent supramolecular polymers (PMFSPs) has not been explored.…”
