Star mesogens — Synthesis and structural characterization using 1D and 2D solution NMR techniques and mesophase characterization
17-10-2013 | A. Shanavas, T. Narasimhaswamy, B.V.N. Phani Kumar, A. Sultan Nasar, Canadian Journal of Chemistry, 2013
Utilisant des approches divergentes, on a réalisé des synthèses de nouveaux mésogènes en forme étoilée à base d'acide trimésique et des portions centrales portant des chaînes latérales symétriques se terminant par des groupes alcoxy. Les portions centrales et les chaînes latérales sont liées ...
Time-resolved photoelectron spectroscopy of adenine and adenosine in aqueous solution
13-06-2013 | Franziska Buchner; Hans-Hermann Ritze; Jan Lahl; Andrea Lübcke, Physical Chemistry Chemical Physics, 2013
Time-resolved photoelectron spectroscopy is applied to study the excited state dynamics of the DNA base adenine and its ribonucleoside adenosine in aqueous solution for pump and probe photon energies in the range between 4.66 eV and 5.21 eV. We follow the evolution of the prepared excited ...
A highly luminescent terbium-organic framework for reversible detection of mercury ions in aqueous solution
12-06-2013 | Hong-Ming Wang; Yang-Yi Yang; Cheng-Hui Zeng; Tian-Shu Chu; Yi-Min Zhu; Ng Seik Weng, Photochemical & Photobiological Sciences, 2013
A new organic-lanthanide framework [TbL1.5(H2O)2]•H2O (1) [H2L = 5-(3΄-carboxylphenyl) nicotinic acid] was synthesized. Its structure was determined by single crystal X-ray diffraction, and the complex was characterized by PXRD, FT-IR, fluorescence and TGA, which features 3D framework with 1D ...
Luminescence spectroscopy of singlet oxygen enables monitoring of oxygen consumption in biological systems consisting of fatty acids
12-06-2013 | Anita Gollmer; Johannes Regensburger; Tim Maisch; Wolfgang Bäumler, Physical Chemistry Chemical Physics, 2013
The interaction of singlet oxygen (1O2) generated in a photosensitized process with well-known reference photosensitizers Perinaphthenone (PN) and TMPyP is investigated in a model system consisting of fatty acids and the respective exogenous photosensitizer (PS) in solution by direct ...
Solution Dynamics of Agostic Interactions in T-Shaped Pt(II) Complexes from Ab Initio Molecular Dynamics Simulations
12-06-2013 | A Lledos; Manuel Angel Ortuño; Pietro Vidossich; Gregori Ujaque; Salvador Conejero, Dalton Transactions, 2013
Transition metal complexes forming agostic interactions have been extensively surveyed. However, the dynamic behaviour of these interactions is less documented though it could be crucial in chemical processes. For this purpose, ab initio molecular dynamics simulations (AIMD) of some ...
Advantages of mechanochemical cocrystallisation in the solid-state chemistry of pigments: Colour-tuned fluorescein cocrystals
12-06-2013 | Dejan-Kresimir Bucar; Stefan Filip; Mihails Arhangelskis; Gareth O. Lloyd; William Jones, CrystEngComm, 2013
Mechanochemical cocrystallisation was utilised to prepare fluorescein cocrystals involving pyridyl-based cocrystal formers, which exhibit different crystal structures and optical properties than those obtained via solution-based crystallisation.
A conical intersection model to explain aggregation induced emission in diphenyl dibenzofulvene
12-06-2013 | Quansong Li; Lluís Blancafort, Chemical Communication, 2013
A conical intersection seam is behind the restriction of intramolecular rotation mechanism for aggregation induced emission in diphenyl dibenzofulvene (DPDBF). In solution, the seam is accessed through rotation around the exocyclic fulvene bond, leading to radiationless decay to the ground ...
High performance organic field-effect transistors based on single-crystal microribbons and microsheets of solution-processed dithieno[3,2-b:2',3'-d]thiophene derivatives
12-06-2013 | Yu Seok Yang; Takuma Yasuda; Hayato Kakizoe; Hiroyuki Mieno; Hiori Kino; Yoshitaka Tateyama; Chihaya Adachi, Chemical Communication, 2013
We present pi-conjugated dithienothiophene derivatives that act as high-performance p-type organic semiconductors. These molecules can self-organize into single-crystal microribbons or microsheets through simple solution processes, where attractive intermolecular S-S interactions induce ...
Microscale pin holders of [small beta]-Co(OH)2 and LiCoO2 having a single-crystalline feature
12-06-2013 | Keisuke Nakajima; Yuya Oaki; Hiroaki Imai, CrystEngComm, 2013
Microscopic pin-holder structures of β-Co(OH)2 having a feature of single crystal were synthesized through multistep crystal growth in an aqueous solution system. The hexagonal plates of the hydroxide were initially produced from an amorphous precursor. The parallel nanoscale pins of ...
Copper ions mediated formation of three-dimensional self-assembly of Ag nanostructure via a facile solution route
12-06-2013 | Shuling Xu; Lei Wang; Haibo Li; Qiaoli Yue; Rui Li; Jifeng Liu; Xiaohong Gu; Shuqiu Zhang, CrystEngComm, 2013
Novel three-dimensional Ag nanoflowers (3DAN) were successfully synthesized through a facile Cu2+ mediated solution method using N, N-Dimethylformamide (DMF) which serves as both a reducing agent and a solvent at room temperature. It was found that the introduction of a trace amount of Cu2+ ...
