“…The binding energy was observed to be reduced further 1 eV while interacting with Hg 2+ ion which confirms the aggregation mechanism and a charge transfer through amine group. Thiocarbazone based probe was reported by Mahajan et al [47] as multi-ions sensor for Ni 2+ , Cu 2+ , Co 2+ and Cd 2+ . The calculated stabilization energy by DFT and the observed result from the fluorescent spectra produced the same order for metal ions binding with probe.…”

A great effort has been devoted to develop the numerical methods to solve Schrödinger equation for atoms and molecules which help to reveal the physico-chemical process and properties of various known/unknown materials. Designing the efficient probe to sense the heavy metals is a crucial process in chemistry. And, during this energy crisis, to find the effective conversion materials for water splitting is an important approach. The density functional theory (DFT) is a powerful tool to identify such materials and made great achievements in the field of heavy metal chemosensor and photocatalysis. Particularly, DFT helps to design the chemosensor for the effective sensor applications. The universe is moving towards the exhaustion of fossil fuels in a decade and so on, DFT plays a vital role to find the green energetic alternative to fossil fuel which is the Hydrogen energy. This book chapter will focus on the application of DFT deliberately on the heavy metal sensors and hydrogen evolution reaction.

“…In this way, the probe is different from other sensors which have response to multiple ions but with similar color change or at the help of extra reagent. [37][38][39][40][41] Since the sensitivity of NA-SP to Cu 2 + is the greatest among tested ions, as observed by its highest absorption intensity under this condition, we then focused on Cu 2 + detection.…”

Though many improvements have been made on fluorescence probes for respective detection of Cu 2 + and Cr 3 + , multiply detect of the ions by a simple colorimetric way in high water content solution sensors remains scarce. In this work, a novel spiropyran hydrazone,which shows aggregation-induced enhancement effects (AIEE) phenomena in EtOH (ethanol)/H 2 O and THF (tetrahydrofuran)/H 2 O media, has been developed. It can detect Cu 2 + colorimetrically having a sensitivity of 105 nM in EtOH/ H 2 O (40/60, v/v) with an unusual specific tandem-response toCr 3 + at a detection limit of 151 nM in addition with a wide pH range of 4-10. Mechanism investigations by HRMS, 1 H NMR and UV-Vis spectroscopy have verified that the response to Cr 3 + is based on the cooperative effect between NA-SP and Cu 2 + , instead of the replacement of Cu 2 + by Cr 3 + . Moreover, NA-SP shows a robust AIEE-caused recognition for Cu 2 + in THF/H 2 O (20/80, v/v) with a detection limit of 16.5 nM. Real water tests indicate that the probe has potential detection application for Cu 2 + in environmental situations. This contribution presents a new spiropyran sensor for the detection of Cu 2 + and Cr 3 + in aqueous solutions through an uncommonly colorimetric way.

“…6 ). 6 The probe can quickly detect Cd 2+ , Co 2+ , Ni 2+ , Cu 2+ in nano-molar level through absorption or fluorescence spectroscopy. Adding Cd 2+ , Ni 2+ , Cu 2+ , Co 2+ to the systems of methanol : water (7 : 3, v/v) and probe 15 for 3–5 minutes causes the probe solution to change from colorless to pale yellow, yellow, yellow, and dark yellow, and the absorption peaks red-shifts from 338 nm to 399 nm, 422 nm, 424 nm, 396 nm, respectively.…”
