Environmental risk assessment of chemicals (ERA) relies on single-species laboratory testing to establish the toxic properties of a compound. However, ERA is not concerned with toxicity under laboratory conditions: it needs to assess the impacts of the compound in the real world. Data-driven statistical analyses (e.

A new rhodamine based turn on florescent probe ()-3',6'-bis(ethylamino)-2-(((6-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)methylene)amino)-2',7'-dimethylspiro[isoindoline-1,9'-xanthen]-3-one (RME) was efficiently synthesized through a simple condensation reaction of 2-amino-3',6'-bis(ethylamino)-2',7'-dimethylspiro[isoindoline-1,9'-xanthen]-3-one and 6-methoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde. The receptor RME is highly non-fluorescent and when copper ions (Cu ions) are added in DMF/water (1 : 2, v/v) medium, the receptor RME exhibits a specific "turn-on" colorimetric and fluorometric response. Moreover, RME binding with Cu ions produced a remarkable color variation that was perceptible to the human eye, changing from colorless to pink.

Anions play a crucial role in various environmental, chemical, and biological processes. Among various anions, the production of perchlorate (ClO ) ion is expected to rise in upcoming years, and thus, an efficient method for the detection of perchlorate ion is highly desirable. In this effort, a pyridyl-benzimidazole-based luminescent probe (RSB1) containing two N-H donor sites has been synthesized for selective detection of perchlorate ion.

Construction of single probes for simultaneous detection of common trivalent metal ions has attracted much attention due to higher efficiency in analysis and cost. A naphthalimide-based fluorescent probe K1 was synthesized for selective detection of Al, Cr and Fe ions. Fluorescence emission intensity at 534 nm of probe K1 in DMSO/HO (9:1, v/v) was significantly enhanced upon addition of Al, Cr and Fe ions while addition of other metal ions (Li, Na, K, Ag, Cu, Fe, Zn, Co, Ni, Mn, Sr, Hg, Ca, Mg, Ce, Bi and Au) did not bring about substantial change in fluorescence emission.
