Precursor-dependent structural diversity in luminescent carbonized polymer dots (CPDs): the nomenclature

Light: Science & Applications, 2021
A wide variety of carbon nanomaterials can be grouped under the category of carbonized polymer dots (CPDs) because of their observed structural diversity. Nomenclature is thus proposed for the better identification of various CPDs materials.

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

Combining high-resolution scanning tunnelling microscopy and first-principles simulations to identify halogen bonding [PDF]

, 2020
Scanning tunnelling microscopy (STM) is commonly used to identify on-surface molecular self-assembled structures. However, its limited ability to reveal only the overall shape of molecules and their relative positions is not always enough to fully solve ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

Advanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

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 assemblies involving metal organic ring interactions: Heterometallic Cu(II)-Ln(III) two dimensional coordination polymers [PDF]

, 2012
Three isostructural two-dimensional coordination polymers of the general formula [Ln2(CuL)3(H2O)9]$5.5H2O, where Ln is La (1), Nd (2), and Gd (3), have been synthesized and isolated from aqueous solutions and their single-crystal structures determined by

Regioselective and Anisotropic Multi‐Patching of Small Microparticles via a Polymer Brush‐Assisted Microcontact Printing (µCP)

Advanced Functional Materials, EarlyView.
A method to fabricate anisotropic SiO2 patchy microspheres is presented using a modified microcontact printing technique. This involves a PDMS elastomer stamp with grooved surface topography, creating a confined environment for the microspheres.

Unveiling the Interstitial Pressure Between Growing Ice Crystals During Ice-Templating Using a Lipid Lamellar Probe [PDF]

, 2020
What is pressure generated by ice crystals during ice-templating? This work addresses this crucial question by estimating the pressure exerted by oriented ice columns on a supramolecular probe composed of a lipid lamellar hydrogel during directional freezing. This process, also known as freeze-casting, has emerged as a unique processing technique for a
