Trapping of ZnCl₂ by bipyridyl-functionalized organotin sulfide clusters, and its effect on optical properties

Abstract

The bipyridyl-terminated cluster [(R4-bipySn)4S6] (R4-bipy = CMe2CH2C(Me)N–NC(H)-4-C10H7N2) traps ZnCl2 units from solution, which affects its optical properties.

Pyrene‐Terminated Tin Sulfide Clusters: Optical Properties and Deposition on a Metal Surface

“…During the past decade, we have developed a family of C=O or C=NNH 2 functionalized organotin sulfide clusters, which serve as a versatile platform for the targeted extension of the organic ligands. The functionalities that are accessible this way vary from the provision of sufficient electron density for generating extreme non‐linear optical properties, [17] through the exposure of bio‐organic groups, [18] to chelate ligands that allow for the targeted trapping of metal ions [19] . This approach also served to synthesize a variety of organotin sulfide compounds with aromatic ligands, [20] which so far comprised relatively small aromatic groups like phenyl, benzyl or naphthyl moieties, [21] some heteroaromatic molecules like benzothiazole, furan, or quinolone [21, 22] or chelate ligands like bipyridyl or bispyridyl [23] .…”

Introducing Distinct Structural and Optical Properties into Organotin Sulfide Clusters by the Attachment of Perylenyl and Corannulenyl Groups

“…By exploitation of the carbonyl group or a hydrazone group formed from it, a synthesis strategy involving mild reaction conditions can be applied, so that molecules with different functionalities can be covalently linked to the inorganic core. In this way, organotin sulfides with attached biomolecules, − chelating ligands for the trapping of metal ions, , and small organic and aromatic , ligands have been achieved. In addition, some compounds exhibiting distinct optical absorption and emission properties have been synthesized.…”

Dinuclear Monoorganostannoxane [(RSnIV)2(μ-OH)(μ-OCH3)Cl4]·CH3OH (R= 2-(Phenylazo)phenyl) Assembled Using Intramolecular Coordination Approach: Design of Organostannoxane-Based NDR Device

“…On the other hand, molecular organotin complexes have been explored very widely in terms of their structure and applications in different areas such as biological activity, gas sensors, ion sensors, optical properties, counter electrode materials in dye-sensitized solar cells, and so forth. − The recent study from our research group reported a molecular organotin sulfide cage [(RSn) 4 S 6 ·4H 2 O·2CHCl 3 ; R = 2-phenylazophenyl]-based device exhibiting the memristive behavior with an excellent on–off ratio of 10 3 . In continuation of our research interests in the organotin-based molecular materials, herein, we report the synthesis, structural characterization, and NDR behavior of monorganostannoxane [(RSn IV ) 2 (μ-OH) (μ-OCH 3 )­Cl 4 ]·CH 3 OH (R = 2-(phenylazo)­phenyl) designed using the intramolecular coordination approach.…”
