Abstract Deep‐red (DR)‐to‐near‐infrared (NIR) phosphorescent organic light‐emitting diodes (OLEDs) have potentials for application in various fields ranging from phototherapy to sensing. Accordingly, herein, phenylpyridazine‐based bidentate ligands are synthesized and subsequently utilized the preparation of dinuclear Pt(II) complexes ( 1 – 6 ). The molecular structures 3 is investigated by single‐crystal X‐ray diffraction, results suggest that these substantially shortened Pt···Pt distances...
We have successfully separated and characterized <italic>E</italic>- <italic>Z</italic>-isomers of diphenyldipyrroethene molecules studies show that the <italic>E</italic>-isomer behaves as AIEgen, whereas <italic>Z</italic>-isomer CIEgen.
The meso-salicylaldehyde substituted BODIPY was synthesized over a sequence of steps and characterized by X-ray crystallography, mass, NMR, absorption, fluorescence electrochemical techniques. crystal structure showed the presence strong intramolecular hydrogen bonding between hydroxyl formyl groups, which induces rigidity in core makes relatively more fluorescent than meso-phenyl BODIPY. Our studies that can be used as specific chemidosimetric sensor for CN(-) ions. group adjacent to helps...
Abstract A series of novel diiridium complexes ( 1 – 4 ) bearing both functional 2‐pyrazolyl‐6‐phenyl pyridine chelate and bidentate phenyl imidazolylidene are synthesized, for which the pyrazolate fragment tridentate also behaves as bridge to hold two iridium atoms in close vicinity. Their structure is unambiguously confirmed using X‐ray determination on corresponding derivative 2a 1,3‐bis(4‐fluorophenyl)‐1H‐Imidazolyl cyclometalate. photophysical electrochemical properties studied further...
Neutral, stable and luminescent metallacycles decorated with furan units, a 2D rectangle four furans 3D trigonal prism six furans, were synthesized from readily accessible starting materials through fac-Re(CO)(3)-directed approach.
Neutral and heteroleptic metallocalix[4]arenes with covalently attached free functionalized benzimidazolyl units were synthesized using Re2(CO)10, a flexible tritopic N donor rigid bis-chelating unit, via one-pot process.
A semirigid ligand, 1,4-bis(2-nonylbenzimidazol-1-ylmethyl)benzene (Nbenzbix), containing a long alkyl chain substituted stator and rotating unit was designed synthesized.
