Azodye−Rhodamine-Based Fluorescent and Colorimetric Probe Specific for the Detection of Pd2+ in Aqueous Ethanolic Solution: Synthesis, XRD characterization, Computational Studies and Imaging in Live Cells

17-12-2014 | Ajit Kumar Mahapatra; Saikat Kumar Manna; Kalipada Maiti; Sanchita Mondal; Rajkishor Maji; Debasish Mandal; Sukhendu ..., Analyst, 2014

Azodye–rhodamine hybrid colorimetric fluorescent probe (L) has been designed and synthesized. The structure of L has been established based on single crystal XRD. It has been shown to act as selective turn-on fluorescence chemosensor for Pd2+ with

Chloride in Lead Chloride-Derived Organo-Metal Halides for Perovskite-Absorber Solar Cells

12-12-2014 | Eva L. Unger; Andrea R. Bowring; Christopher J. Tassone; Vanessa L. Pool; Aryeh Gold-Parker; Rongrong Cheacharoen; K ..., Chemistry of Materials, 2014

Organo-metal halide perovskites are an intriguing class of materials that have recently been explored for their potential in solar energy conversion. Within a very short period of intensive research, highly efficient solar cell devices have been demonstrated. One of the heavily debated questions ...

Ternary System Based on Fluorophore–Surfactant Assemblies—Cu2+ for Highly Sensitive and Selective Detection of Arginine in Aqueous Solution

11-12-2014 | Jianhua Cao; Liping Ding; Wenting Hu; Xiangli Chen; Xiao Chen; Yu Fang, Langmuir, 2014

A new cationic dansyl derivative-based (DIlSD) fluorescence probe was designed and synthesized. Its combination with anionic surfactant SDS assemblies shows enhanced fluorescence intensity and blue-shifted maximum wavelength. Its fluorescence can be slightly quenched by Cu2+; however, the ...

Synthesis and High Solid-State Fluorescence of Cyclic Silole Derivatives

11-12-2014 | Yuanjing Cai; Kerim Samedov; Brian S Dolinar; Zhegang Song; Ben Zhong Tang; Chaocan Zhang; Robert West, Organometallics, 2014

Cyclotetrasiloxanes 1–3 containing different silole-based fluorogenic units (silafluorene, 1,3-diphenyl-9-silafluorene, tetraphenylsilole) were synthesized by cohydrolysis and condensation reactions. Their optical properties in solution and as crystals were studied. These compounds have low ...

Temperature Driven Macromolecule Separation by Nanoconfinement

10-12-2014 | Ilaria De Santo; Filippo Causa; Paolo A. Netti, Macromolecules, 2014

We focused on the influence of temperature variations on macromolecule partitioning between unconfined and nanoconfined areas in nanoslits using single molecule measurements. We evaluated the number of fluorescent poly(ethylene glycol) (PEG) molecules confined in glass nanoslits in several ...

Evidence of anti-parallel dimer formation of 4-cyano-4[prime or minute]-alkyl biphenyls in isotropic cyclohexane solution

09-12-2014 | Shunzo Takabatake; Toshiyuki Shikata, Physical Chemistry Chemical Physics, 2014

The formation of anti-parallel dimers of two liquid crystal forming 4-cyano-4′-alkyl biphenyls (nCB, n = 5 (pentyl) and n = 8 (octyl)) was confirmed in an isotropic cyclohexane solution (nCB–cH). In addition to high frequency dielectric relaxation (DR) measurements up to 50 GHz, fluorescence ...

Design and Characterization of 4,5‐Bis(diarylamino)phthalic Acid Diesters as a New Class of Fluorophores Exhibiting Efficient Blue Emission in the Solid State

05-12-2014 | Masaki Shimizu, Tomokazu Tamagawa, European Journal of Organic Chemistry, 2014

Abstract We developed 4,5‐bis(diarylamino)phthalic acid diesters as blue fluorophores exhibiting efficient photoluminescence in powder and in a thin film of pol(methyl methacrylate). Increasing the electron‐donating nature of the substituents in the para positions of the diarylamino moieties ...

Toward a New Family of Bifunctional Organoiron Dendrimers: Facile Synthesis, Redox, and Photophysical Fingerprints

03-12-2014 | Alaa S. Abd‐El‐Aziz, Christian Agatemor, Nola Etkin, Rabin Bissessur, Macromolecular Chemistry and Physics, 2014

Multifunctional macromolecules continue to attract attention. Here, three generations of a new family of bifunctional organoiron dendrimers are reported, which are synthesized from a redox‐active organoiron complex, η6‐dichlorobenzene‐η5‐cyclopentadienyl‐iron(II). The facile chemistry of the ...
