Synthesis, crystal structure, spectroscopic and photoluminescence studies of manganese(II), cobalt(II), cadmium(II), zinc(II) and copper(II) complexes with a pyrazole derived Schiff base ligand

Synthesis, spectral characterization, molecular modeling, antibacterial and antioxidant activities and stability study of binuclear Pd(II) and Ru(III) complexes with novel bis-[1-(2-[(2-hydroxynaphthalen-1-yl)methylidene]amino}ethyl)-1-ethyl-3-phenylthiourea] ligand: Application to detection of cholesterol

“…Thus, the fluorescence intensity can be increased or decreased upon coordination. The ligand binding to the palladium ion increases the conformational rigidity of the ligand (formation of stable Pd complex) [48] and decreases the intensity of fluorescence with non-radiative energy loss.…”

Synthesis, structure and photoluminescence of (PLAGH)2[ZnCl4] and comparative analysis of photoluminescence properties with tris(2,2′-bipyridine)ruthenium(II)

“…Further comparison of photoluminescent spectra with the compounds in the area of interest can be found in Refs. [50][51][52].…”

“…Additionally investigation of the Zn(II) frameworks in terms of photoluminescence was thoroughly performed in the recent time [9,10]. On one hand, it is worth examining affinities of the organic materials to different metals, and determining sensitivity and selectivity to the aforementioned [9][10][11][12][13][14][15].…”

“…On one hand, it is worth examining affinities of the organic materials to different metals, and determining sensitivity and selectivity to the aforementioned [9][10][11][12][13][14][15]. These properties can be used for the metal detectors or one-time indicators in liquids.…”

Synthesis and spectroscopic properties of a fluorosensor for Zn2+ ions

“…Excitation at the highest energy absorption band, 313 nm, revealed very weak emission. Normally in the presence of coordinating Zn(II) ions, the fluorescence of a ligand is enhanced by preventing the photo induced electron transfer (PET) process in the ligand [15]. This explains the intense emission of the complex at an excitation wavelength of 368 nm as this absorption is based on L-Zn(II) transition.…”
