Pyrophosphate (PPi) anions are crucial in numerous biological and ecological processes involved in energy conversion, enzymatic reactions, and metabolic regulation along with adenosine. They are also significant biological markers for various processes related to diseases. Fluorescent PPi sensors would enable visual and/or biological detection in convenient settings. However, the current availability of commercial sensors has been limited to costly enzymes that are not compatible for imaging. Sensor development has also encountered challenges such as poor selectivity and stability and limited practical applications. In this review, we analyze the situation of PPi sensing via commercial kits and focus on sensors that use metal complexes. We address their designs, sensing mechanisms, selectivities, and detection limits. Finally, we discuss limitations and perspectives for PPi detection and imaging.

“…Supramolecular polymers (SPs), as a class of supramolecular assemblies, are polymers formed by noncovalent interactions of monomer units or macromolecular building blocks. , The noncovalent interactions of the SP mainly include hydrogen bonding, metal coordination, host–guest interaction, π–π stacking, etc. Due to the reversible properties of noncovalent interactions, SPs can exhibit various responsiveness by an external stimulus.…”

Three different monomers, A 2 B 2 , C 2 , and D 2 , were synthesized. The monomers A 2 B 2 + C 2 could self-assemble to form a linear supramolecular polymer (SLP) by crown ether-based host−guest interactions at high concentrations. The electrospun nanofibers could be prepared from the SLP solution. When adding monomer D 2 to the SLP solution, the SLP transformed into a cross-linked supramolecular polymer (SCP) through the pillar[5]arene (P5)-based host−guest interaction. The SCP exhibited enhanced fluorescence emission compared to D 2 due to the inhibition of electron transfer between the P5 group and the borondipyrromethene (BODIPY) group on D 2 . When the concentration of monomer A 2 B 2 exceeded 85 mM, the SCP turned into a SP gel and emitted green fluorescence. The gel exhibited multiple stimuli-responsiveness such as K + and temperature responsiveness. The reversible transition of sol−gel could be achieved by K + or temperature control, accompanied by a change of the fluorescence intensity. Additionally, the SCP gel had good self-repairing ability and thermal stability.

“…[20][21][22] Tetraphenylethylene (TPE) is a star molecule of AIE materials, widely used due to its simple synthesis, modification, and unusual luminescence. [23][24][25][26][27][28][29][30][31][32][33][34][35][36] A series of eightshaped double macrocycles can be formed by connecting the benzene rings of TPE in pairs (Scheme 1). These structures have received great attention, leading to a series of studies on the AIE mechanism, ion recognition, and multicolor luminescence.…”
