A simple and efficient protocol for 9-(4-methoxyphenyl)-3,3,6,6-tetramethyl-3,4,6,7,9,10-hexa hydroacridine-1,8(2H,5H)-dione (MPTH) was synthesised by conventional method by using efficient nano catalyst. The crystallite sizes (L) and surface area (S) of TiO2 are 10.44 nm and 140.32 m2/g. MPTH displayed wide inhibitions on the KB cell appearance with IC50 values 25.06 μg. The IC50 values of the MPTH imply that methoxy substituted compound holds more inhibitory effect against the cancer cells.

Novelnitrogen-containing moieties were prepared and analyzed by various techniques like NMR and mass spectrometry. The antimicrobial and anti-oxidant behaviors of novel moieties have been screened. The synthesized moieties are better antimicrobial activities. The moieties 1-5 are the greatest antioxidant reagents in the DPPH process. The IC50 standards are 0.13, 0.14, 0.11, 0.16, and 0.11 μg/Ml, respectively. Compound 3, 5 (IC50 = 0.11 μg/mL) was the most potent compound with –OCH3 and –CH3 groups as substituents showing good antioxidant activity even at very low concentrations. The particulars of synthetic methods, spectroscopic data, and biological results are recorded.

Novel azo moieties were synthesized and confirmed by technical characterization. Antimicrobial screening activity was done by the moieties 1and 2 with respective strains. Theoretical calculations like HOMO – LUMO, MEP, and Mulliken populations were done by DFT using B3LYP/6-31G (d,p) basis set.

The ligand was recognized by IR, NMR and mass spectra’s. An marvelous fluorescence enrichment was establish in the survival metals outstanding inhibition of radiation less transitions beginning the n-π* state in the chemosensor. The binding interface has been confirmed by an on account of UV–Visible, Photoluminescence and CV. Ligand exhibits a well-built fluorescence emission; in difference to this half-done fluorescence quenching phenomena is observed. Theoretical studies was done by using B3LYP/6-31G (d,p) method.

A cobalt (II)-doped tetrakis(thiourea)nickel(II) chloride (TTNC) green quartz crystals are developed by sluggish disappearance method. FT-IR studies signify the thiourea group and water of crystallization. Doping was established via UV–vis spectra. The powder precursors were characterized by TG/DTA, after calcination between 225 and 343 ◦C. The developed crystal was established by powder X-ray diffraction, it is confirmed crystal system comes out to be tetragonal. Surface morphological changes owing to doping are observed by SEM, EDS spectroscopies. It is found that the cycle stability is improved by adding small amount of Co(II). Microstructures of the materials reveal that cobalt additions influence the average grain size and the pore distribution. Doping with Co(II) increases five times the preferential growth. As a consequence, plate-like morphology is observed. The doping of cobalt (II) in TTNC indicates that cobalt can partially substitute the metal sties of TTNC, which can lead to the modification of physical and chemical properties of the parent compound. The crystal is further characterized by Kurtz powder technique.
