High Fluorescent Porphyrin-PAMAM-Fluorene Dendrimers
Molecules, 2015 Two new classes of dendrimers bearing 8 and 32 fluorene donor groups have been synthesized. The first and second generations of these porphyrin-PAMAM-fluorene dendrimers were characterized by 1H-NMR, 13C-NMR, FTIR, UV-vis spectroscopy, elemental analyses

Photocatalytic Degradation of Anti-inflammatory Drug on Ti Doped BaBiO3 Nanocatalyst under Visible Light Irradiation [PDF]
Iranica Journal of Energy and Environment, 2016 Nanosized perovskites BaBiO3 and BaBi4Ti4O15 were prepared using Pechini method. These structures were confirmed through thermogravimetric analysis (TGA), X-ray diffraction (XRD), UV-Vis diffusion reflection spectroscopy (UV-Vis DRS), Fourier transform ...

Advanced Functional Materials, EarlyView.In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Advanced Functional Materials, EarlyView.A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.
