“…The chelated bidentate binding modes have been kept here among the possible binding modes of the dyes with the (TiO 2 ) 9 cluster (see Figure 5 ). Numerous dyes with a carboxyl anchor group have been determined to be stable for this bidentate bridging mode [ 59 , 60 ].…”

The efficiency of the newly designed dye-sensitized solar cells (DSSCs) containing triphenylamine, diphenylamine (TPA), phenothiazine, and phenoxazine as donors and triazine, phenyl with D1-D2-π-linker-π-(A)2 architecture has been investigated using density functional theory (DFT) and time-dependent (TD-DFT) methods. These methods were used to investigate the geometrical structures, electronic properties, absorption, photovoltaic properties, and chemical reactivity. Furthermore, the calculated results indicate that different architectures can modify the energy levels of HOMO and LUMO and reduce the energy gap. The absorption undergoes a redshift displacement. This work aims at calculating the structural geometries and the electronic and optical properties of the designed dyes. Furthermore, the dye adsorption characteristics, such as the optoelectronic properties and the adsorption energies in the TiO2 clusters, were calculated with counterpoise correction and discussed.

[14,15] Phenothiazine, an electron-donating group, can also create fluorescent probes that are founded on the ICT instrument pattern by combining with robust acceptors to create a 'pull-push' system. [16] It is becoming increasingly common to create the stiff planar construction of phenothiazine that endorses the creation of dual-responsive or ratiometric fluorescence probes with lengthy emission wavelengths.…”

Synthesis and characterization of phenothiazine sensor for spectrophotometric and fluorescence detection of cyanide

et al. 2023

A sensitive and selective phenothiazine‐based sensor (PTZ) has been successfully synthesized. The sensor PTZ displayed specific identification of CN− ‘turn‐off’ fluorescence responses with a quick reaction and strong reversibility in an acetonitrile:water (90:10, V/V) solution. The sensor PTZ for detecting CN− exhibits the marked advantages of quenching the fluorescence intensity, fast response time (60 s), and low value of the detection limit. The concentration that is authorized for drinking water by the WHO (1.9 μM) is far higher than the detection limit, which was found to be 9.11 × 10−9. The sensor displays distinct colorimetric and spectrofluorometric detection for CN− anion due to the addition of CN− anion to the electron‐deficient vinyl group of PTZ, which reduces intramolecular charge transfer efficiencies. The 1:2 binding mechanism of PTZ with CN− was validated by fluorescence titration, Job's plot, HRMS, 1H NMR, FTIR analysis, and density functional theory (DFT) investigations, among other methods. Additionally, the PTZ sensor was successfully used to precisely and accurately detect cyanide anions in actual water samples.
