Bispidine-Based Macrocycles: Achievements and Perspectives

Organics, 2023
This review presents all currently known macroheterocyclic compounds that include a bispidine (3,7-diazabicyclo[3.3.1]nonane) fragment in their structure. A classification of bispidine-containing macroheterocycles, which is based on the ring size and the

Ferrocene as an iconic redox marker: from solution chemistry to molecular electronic devices [PDF]

arXiv, 2022
Ferrocene, since its discovery in 1951, has been extensively exploited as a redox probe in a variety of processes ranging from solution chemistry, medicinal chemistry, supramolecular chemistry, surface chemistry to solid-state molecular electronic and spintronic circuit elements to unravel electrochemical charge-transfer dynamics.

Spider Silk: Rapid, Bottom‐Up Self‐Assembly of MaSp1 into Hierarchically Structured Fibers Through Biomimetic Processing

Advanced Functional Materials, EarlyView.
Spider dragline silk has extraordinary mechanical properties due to the underlying hierarchical organization of the fiber across multiple length scales. A biomimetic platform for MaSp1 is developed, the main protein component of dragline silk, and thereby elucidates the parameters governing its rapid self‐assembly from soluble protein into complex ...

Dye‐Sensitized Solar Cells Inspired Method to Modulate Photo‐Induced Charge Transfer Efficiency for Enhancing the SERS Activity of Semiconductor

Advanced Materials Interfaces, EarlyView., 2023
The conduction band (CB) edge and surface state energy level of TiO2 nanoparticles shift downward with increasing Li+ concentration, which facilitates the charge‐transfer interaction between the molecules and the surface enhanced Raman scattering substrates. Abstract While the Lithium ion modification strategy is widely adopted in tuning the bandgap of

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Investigation of supramolecular architectures of bent-shaped pyridine derivatives: from a three-ring crystalline compound towards five-ring mesogens [PDF]

New J. Chem. 40, 6977-6985 (2016), 2016
In searching for novel photoactive liquid crystals, we have synthesized a series of five-ring pyridine-based bent-core compounds bearing different substituents at the peripheral phenyl rings (CH3O, Cl and NO2). Their mesomorphic behaviour has been investigated by polarizing optical microscopy, differential scanning calorimetry and X-ray scattering, and

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Flexible single-layer ionic organic–inorganic frameworks towards precise nano-size separation

Nature Communications, 2016
Membranes composed of ionic frameworks offer applications in nano-size separation thanks to their highly regular pores. Here, the authors devise such a system composed of polyoxometalates and organic pseudorotaxanes, and demonstrate their ability to ...

Highly Integrated Organic-Inorganic Hybrid Architectures by Non-Covalent Exfoliation of Graphite and Assembly with Zinc Oxide Nanoparticles [PDF]

Adv. Mater. Interfaces 2016, 3, 1600365, 2018
Herein, we report an easy, straight forward, and versatile approach to build 0D/2D hybrid nanoparticle/graphene architectures by means of non-covalent chemistry and a modified Layer-by-Layer assembly. Three water soluble perylene diimides were employed to efficiently exfoliate pristine graphite into positively charged few- and multilayer graphene ...

Supramolecular Chemistry … and Beyond

Angewandte Chemie International Edition, 2015
The research group of Jean-Marie Lehn recently celebrated its 50th anniversary. Lehn, who shared the Nobel Prize in Chemistry 1987 with Donald J. Cram and Charles J. Pedersen, has been active in many initiatives in the European chemical community, and was instrumental in the founding of Chemistry-A European Journal and ChemBioChem.
