N-salicylideneamine derivatives with TEMPO substituents.
Three N-salicylideneamine derivatives bearing TEMPO (2,2,6,6-tetra- methyl-1-piperidinyloxy) substituents were prepared in order to study their structure and property relationships and to investigate the possibilities of the existence of heat and/or light responsive magnetic properties. Curie-Weiss behavior with weak ferromagnetic intermolecular spin-spin interactions was observed in one of the...
متن کاملSynthesis and photodynamic activity of zinc(II) phthalocyanine derivatives bearing methoxy and trifluoromethylbenzyloxy substituents in homogeneous and biological media.
Two zinc(II) phthalocyanines bearing either four methoxy (ZnPc 3) or trifluoromethylbenzyloxy (ZnPc 4) substituents have been synthesized by a two-step procedure starting from 4-nitrophthalonitrile. Absorption and fluorescence spectroscopic studies were analyzed in different media. These compounds are essentially non-aggregated in the organic solvent. Fluorescence quantum yields (phi(F)) of 0.2...
متن کاملPhotoswitchable fluorescent diarylethene derivatives with short alkyl chain substituents.
The sulfone derivatives of 1,2-bis(2-alkyl-6-phenyl-1-benzothiophen-3-yl)perfluorocyclopentene having various short alkyl chain substituents at reactive carbons were prepared and the effect of alkyl substitution on the fluorescence property of the closed-ring isomers was studied. Upon irradiation with ultraviolet (UV) light the derivatives exhibit a brilliant green fluorescence under irradiatio...
متن کاملScreening of Anticancer Activity in Newly Synthesized Benzothiazole Derivatives
In present study novel series of benzothiazole derivatives were synthesized and their anti cancer efficacy was analyzed using cancer cell lines (Human Chronic Myelogenous Leukemia). The compounds were synthesized by simple and facile procedures and characterized by IR, H-NMR and Mass spectra study. The synthesized compounds were screened for anti cancer activity using in vitro assays. The compo...
