Abstract Dicationic bis‐quinolinium salts possessing different types of conjugation are presented in which the hetareniums separated by acetylenic or 1,4‐diethynylbenzene spacers. Cross‐conjugation is induced interconnections via 3‐positions heteroareniums, and realized 2,2/2,4/4,4‐interconnections. We also synthesized mixed cross‐conjugated/conjugated 2,3/4,3‐interconnected species. The determ...

The synthesis, photophysical and electrochemical properties of hexyl thiophene substituted thieno[b]-fused BODIPY structure are reported within this work. One such derivative, HTFBod, has been studied, which is one the rare compounds that a maximum absorbance wavelength greater than 750 nm among fused compounds. In addition, it preserves its significant spectral as high molar absorptivity fluor...

• Soft crystals exhibiting mechanochromic luminescence (MCL). Reviewing the systematic studies on MCL behaviors of soft crystals. Controlling molecular conformation and packing structure Emphasizing remarkable steric effects substituents properties MCL. are a class smart materials that can switch their photophysical or mechanical in response to gentle external stimuli. A representative stimuli-...

Metal nanoparticles (NPs) confined on the surface of flexible polymers films are highly sought after for a diverse range applications. Herein, we report facile substrate-independent strategy surface-confined growth silver NPs (AgNPs) surfaces chemically polymer film substrates represented by polypropylene (PP), polyvinyl chloride (PVC), and polyethylene terephthalate (PET). The were subjected t...

Polycyclic aromatic hydrocarbons (PAHs) with a one‐dimensional (1D), ribbon‐like structure have the potential to serve as both model compounds for corresponding graphene nanoribbons (GNRs) and materials optoelectronics applications. However, synthesizing molecules of this type extended π‐conjugation presents significant challenge. In study, we present straightforward synthetic method series bis...

The effects of halide-ligand exchange and Cu Ag doping are studied on structural, optical, electrical properties four monolayer CdSe nanoplatelet (NPL) NPL thin films. Combinational study shows that NH4Cl-treatment films show tetragonal lattice distortion NPL, side-to-side attachment between NPLs, bathochromic shift in absorption spectra, complete quenching band-edge dopant-induced emissions. F...

under prolonged diabetic conditions, hba1c is produced from normal hemoglobin (hba0) through a non-enzymatic glycosylation or glycation, a process which enhances the hemoglobin susceptibility to be auto-oxidized to methemoglobin (methb). here we are reporting that the non-enzymatic reaction between fructose and methb (methb fructation) induces significant changes in the globin structure and deg...

In this study, a quinoline-4-carboxylic acid derivative was synthesized through Pfitzinger reaction. reaction, isatin is modified via its reaction with ketone and refluxed for 24 h to obtain acid. The presence of carboxylic group identified by Fourier Transform Infrared (FTIR) spectroscopy ultraviolet–visible (UV-Vis) spectrophotometry. results showed that the absorption peaks C=O O–H stretchin...

In this investigation, influences on solution behavior and solvatochromism caused by the attachment of a 1H,1H,2H,2H-perfluorooctyl side chain onto derivatives well-known Brooker's Merocyanine (BM) chromophore are explored. Starting from either 4-picoline or 2-picoline, corresponding polyfluoroalkylated o- p-BM have been synthesized in three steps. For all dyes, UV–Vis measurements were conduct...
