Emerging Opportunities of Colloidal Quantum Dots for Photocatalytic Organic Transformations

open access: yesAdvanced Materials, EarlyView.
Colloidal quantum dots (QDs) have gained significant attention as photocatalysts in organic transformations in recent years. This review highlights QDs’ distinctive features, including the quantum size effect, compositional and structural diversity, tunable surface chemistry, and photophysics.

Reaction of Some Substituted (Un)Substituted Isatins with 1,ω-Alkanes and Their Products with Sodium Azide

open access: yesChemistry Proceedings, 2021
Azide derivatives of isatins were the initial materials needed for click chemistry, so as to form 1,2,3-triazoles in order to synthesize the hybrid compounds of 1,2,3-triazole–isatin with monosaccharide moieties.

Aryne Acyl-Alkylation in the General and Convergent Synthesis of Benzannulated Macrolactone Natural Products: An Enantioselective Synthesis of (−)-Curvularin [PDF]

open access: yes, 2010
A general approach for the synthesis of benzannulated macrolactone natural products utilizing an aryne acyl-alkylation reaction is described. Toward this end, the total syntheses of the natural products (−)-curvularin, curvulin, and (−)-diplodialide C ...

High‐Yield Bioproduction of Extracellular Vesicles from Stem Cell Spheroids via Millifluidic Vortex Transport

open access: yesAdvanced Materials, EarlyView.
Stem cell spheroids, produced via a high‐throughput microfabrication technique, are transported within a vortex generated at the outlet channels of a cross‐slot millifluidic chip. For Reynolds number exceeding 170–200, intermittent high shear stresses applied to each spheroid within the vortex trigger a massive release of biologically active ...

Methyl 3,3-Bis[4-(dimethylamino)phenyl]-2,2-dimethylpropanoate

open access: yesMolbank, 2023
The synthesis of methyl 3,3-bis[4-(dimethylamino)phenyl]-2,2-dimethylpropanoate is achieved by means of the alkylation of methyl isobutyrate silyl enol ether with bis[4-(dimethylamino)phenyl]methanol, facilitated by using 1,1,1,3,3,3 ...

Molecular Tuning of the Magnetic Response in Organic Semiconductors

open access: yes, 2017
The tunability of high-mobility organic semi-conductors (OSCs) holds great promise for molecular spintronics. In this study, we show this extreme variability - and therefore potential tunability - of the molecular gyromagnetic coupling ("g-") tensor with

Transhydrogenation of propyne with butane over a vanadia/θ-alumina catalyst [PDF]

open access: yes, 2015
The transhydrogenation of propyne and butane was studied over a 1 % VO x /alumina catalyst at 873 K. In the absence of the vanadia, the alumina support was active for cracking and alkylation.

High‐Performance n‐Type OFETs Enabled by Pyridine‐Substituted Diketopyrrolopyrrole Organic Semiconductor and Elastomer Stretchable Blends

open access: yesAdvanced Materials Technologies, EarlyView.
Two n‐type small molecules (DPPPy‐C10‐TN and DPPPy‐C‐Si‐TN) based on alkyl/siloxane‐substituted pyridine flanked diketopyrrolopyrrole (DPPPy) end capped with thienyl naphthalimide (TN) for organic filed effect transistors (OFETs) are reported. Interestingly, bottom‐gate top‐contact OFETs based on DPPPy‐C‐Si‐TN:SEBS blend show a high electron mobility ...

Regioselective Synthesis of New Family of 2-Substituted 1,2,3-Triazoles and Study of Their Fluorescent Properties

open access: yesMolecules, 2023
Modification of 5-aryl-4-trifluoroacetyltriazoles at the NH-moiety was investigated. Screening of the alkylation conditions revealed that using Na2CO3 as a base and DMF as a solvent of 2-substituted triazoles can be preferentially prepared in up to 86 ...
