“…The highly sensitive and selective detection of pH is extremely important because pH plays an important role in various physiological, chemical and physical processes, such as tumor growth, [ 47‐49 ] ion transport, [ 50‐51 ] catalytic reaction, [ 52‐53 ] and energetic conversion. [ 54‐56 ] The above mentioned pH‐controlled multicolor luminescence could be perfectly applied in the detection of pH from 5 to 10 by naked eyes.…”

In this work, a spherical calixpyridinium-IR-820 supramolecular assembled material was fabricated based on the calixpyridiniuminduced IR-820 aggregation. This assembled material exhibited a well visible light responsiveness by the photodecomposition of aggregated IR-820 accompanied by an obvious color change. Such photochromic material has many potential applications. More interestingly, the photodecomposition of aggregated IR-820 was significantly promoted, although the aggregated photosensitizers usually exhibited a lower photoreactivity. This approach can be further extended to construct various visible-light responsive supramolecular assembled materials and potentially applied in many fields. Herein, benefitting from the pH-dependent luminescent properties of calixpyridinium and the photodegradation products of IR-820, a pH-controlled visual multicolor luminescence was achieved, which was perfectly applied in the detection of pH from 5 to 10 by naked eyes.

“…Organic photoelectric sensing materials have been attracting considerably more attention recently due to their superiorities, i.e., easy and scalable synthesis, adjustable spectral bands, and facilely structural modification, which have been applied widely in the fields of new energy conversion, − nonlinear optics, , optical data storage, , photodynamic therapy, − heavy metal monitoring, , biological sensing, − and environmental monitoring − with excellent performances. However, organic instability would be quite an insurmountable obstacle, which is an urgent problem needing to be solved.…”

A convenient and efficient method to eliminate the aggregation effect of organic photoelectric sensing materials and to improve biological compatibility and cell permeability as well was developed by hanging organic fluorophores on a polymer chain, for example, fluorescein fluorophores had been controllably hung on polyacrylamide main chains with a 1:2 stoichiometric ratio by a simple copolymerization strategy. The results showed that introduction of water-soluble bioactive polyacrylamide main chains into fluorescein fluorophores via covalent bonds could effectively improve their optical stability by deteriorating π–π stack and charge-transfer interactions among different fluorophores. More importantly, the resultant materials possessed low toxicity and excellent cell permeability ten times larger than their precursor fluorescein fluorophore, which made it express an especially turn-on fluorescent response to ultratrace Hg2+ both in aqueous and living cells by forming stable 5-member-ring complexes with Hg2+ with a correlation coefficient of 0.997 and a low detection limit of 4.0 × 10–10 mol·L–1. This work provides promising insight into constructing some practical sensing materials for environmentally-friendly biological analyses.

The presence of heavy metals in industrial effluents has recently become a source of concern for human health because of their toxicity. The released heavy metals have the potential to accumulate in living organisms, resulting in the development of a number of diseases and disorders. A promising response with high precision can be obtained through the development of prospective nanomaterials when a sensitive and selective determination of heavy metals is required. However, in order to be successful, the latest electrochemical sensing approaches need substantial enhancement in rapid response, signal amplification and, specificity. To achieve these requirements using an electrochemical pathway for detection of heavy metals at low cost, the evolution of hybrid materials has emerged as a new type of functional materials. On the basis of this review, we will examine and highlight the most recent developments in the synthesis of inorganic-graphene hybrid materials for enhancing the sensing behavior of toxic metals are discussed.
