Multi-dimensional copper(I) and silver (I) coordination polymers assembled with a pyridyl bis-urea macrocyclic ligand

Autor: Linda S. Shimizu, Mark D. Smith, Bozumeh Som

Publikováno v: Polyhedron. 201:115170

We report the synthesis of a new flexible multimodal macrocyclic ligand, protected pyridyl bis-urea macrocycle 1, and two of its coordination polymers Cu2I2(1)2·(CH3CN)1.63 (2) and [Ag(1)](NO3).(H2O)2.49 (3). The ligand possesses conformational flex

This paper describes the use of polarized fluorescence microscopy to directly probe guest molecule orientation in bis-urea macrocycle crystals. These macrocycles assemble to afford one-dimensional (1D) microchannels ∼9 A in diameter that have previ

Pillars of assembled pyridyl bis-urea macrocycles: a robust synthon to organize diiodotetrafluorobenzenes

Autor: Bozumeh Som, Linda S. Shimizu, Mark D. Smith, Sahan R. Salpage, Juno Son, Stavros Karakalos, Bing Gu

Publikováno v: CrystEngComm. 19:484-491

Columnar assembled pyridyl bis-urea macrocycles 1 provide a strong 1D supramolecular synthon to construct hierarchical assemblies. These 1D pillars contain ditopic symmetrical acceptors in the form of basic oxygen lone pairs. Herein, we probe this sy

Pyridyl-phenylethynylene bis-urea macrocycles: self-assembly and utility as a nanoreactor for the selective photoreaction of isoprene

Autor: Yuewen Xu, Linda S. Shimizu, Ammon J. Sindt, Bozumeh Som, Sahan R. Salpage, Mark D. Smith

Publikováno v: RSC Advances. 6:98350-98355

Porous organic crystalline materials were obtained by the self-assembly of pyridyl-phenylethynylene bis-urea macrocycles (1). In contrast to the typical columnar assembly of other bis-urea macrocycles, 1 assembled into interdigitated layers to afford

Temperature-induced pseudopolymorphism of molecular salts from a pyridyl bis-urea macrocycle and naphthalene-1,5-disulfonic acid

Autor: Bozumeh Som, Linda S. Shimizu, Mark D. Smith, Jessica R. Shue

Publikováno v: Acta crystallographica. Section C, Structural chemistry. 74(Pt 1)

Molecular salts, often observed as cocrystals, play an important role in the fields of pharmaceutics and materials science, where salt formation is used to tune the properties of active pharmaceutical ingredients (APIs) and improve the stability of s

Structural, electrochemical and photophysical properties of an exocyclic di-ruthenium complex and its application as a photosensitizer

Autor: Linda S. Shimizu, Mark D. Smith, Sahan R. Salpage, Aaron K. Vannucci, Avishek Paul, Bozumeh Som, Tanmay Banerjee, Kenneth Hanson

Publikováno v: Dalton transactions (Cambridge, England : 2003). 45(23)

The reaction of cis-bis(2,2′-bipyridine)dichlororuthenium(II) hydrate with a conformationally mobile bipyridyl macrocycle afforded [(bpy)2Ru(μ-L)Ru(bpy)2]Cl4·6H2O, a bridged di-Ru complex. Single crystal X-ray diffraction showed the macrocyclic l
