Chinnasamy, Ragaverthini;Ravi, Jada;Vinay Pradeep, Vuppu;Manoharan, Deepak;Emmerling, Franziska;Bhattacharya, Biswajit;Ghosh, Soumyajit;Chandrasekar, Rajadurai research published 《 Adaptable Optical Microwaveguides From Mechanically Flexible Crystalline Materials》, the research content is summarized as follows. Flexible organic crystals (elastic and plastic) are important materials for optical waveguides, tunable optoelectronic devices, and photonic integrated circuits. Highly elastic organic crystals of a Schiff base, 1-((E)(2,5-dichlorophenylimino)Me)naphthalen-2-ol (1), and an azine mol., 2,4-dibromo-6-((E)((E)(2,6-dichlorobenzylidene)hydrazono)Me)phenol (2) are presented. These microcrystals are highly flexible under external mech. force, both in the macroscopic and the microscopic regimes. The mech. flexibility of these crystals arises of weak and dispersive C-H···Cl, Cl···Cl, Br···Br, and π···π stacking interactions. Singly and doubly-bent geometries were achieved from their straight shape by a micromech. approach using the AFM cantilever tip. Crystals of mols. 1 and 2 display a bright-green and red fluorescence (FL), resp., and selective reabsorption of a part of their FL band. Crystals 1 and 2 exhibit optical-path-dependent low loss emissions at the termini of crystal in their straight and even in extremely bent geometries. The excitation position-dependent optical modes appear in both linear and bent waveguides of crystals 1 and 2, confirming their light-trapping ability.
Category: bromides-buliding-blocks, 3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes.
3,5-Dibromosalicylaldehyde, also known as 3,5-Dibromosalicylaldehyde, is a useful research compound. Its molecular formula is C7H4Br2O2 and its molecular weight is 279.91 g/mol. The purity is usually 95%.
3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
