Abstract Precise mechanical processing of optical microcrystals involves complex microscale operations viz. moving, bending, lifting, and cutting crystals. Some these can be implemented by applying force at specific points the crystal to fabricate advanced crystalline junctions. Mechanically compliant flexible crystals are ideal candidates for designing such microoptical A vapor‐phase growth naturally bent waveguiding 1,4‐bis(2‐cyanophenylethynyl)benzene ( 1 ) on a surface forming different...
The 1,2,4-triazole system has shown excellent electron-transport and hole-blocking properties owing to its highly electron-deficient nature. Accordingly, a large number of derivatives have been described as having wide variety uses in materials science. Triazoles are widely used transition-metal complexes or metal-organic frameworks (MOFs), but metal-free also exhibited interesting useful materials. use these derivatives, either small molecules polymers, light-emitting devices allowed the...

Abstract The synthesis of a series 4‐aryl‐3,5‐bis(arylethynyl)aryl‐4 H ‐1,2,4‐triazoles derivatives is reported and the influence exerted by peripheral substitution on morphology aggregates generated from these 1,2,4‐triazoles investigated SEM imaging. presence paraffinic side chains results in long fibrillar supramolecular structures, but unsubstituted triazoles self‐assemble into thinner ribbons needle‐like aggregates. crystals obtained methoxy‐substituted have been utilised to elaborate...
In this work, as an equivocal proof of the potential microwave irradiation in organic synthesis, a complex pyrazine-decorated benzotriazole derivative that is challenging to prepare under conventional conditions has been obtained upon irradiation, thus efficiently improving process and yields, dramatically decreasing reaction times resulting environmentally friendly synthetic procedure. addition, useful could be applied electronics, specifically field-effect transistors (OFETs), exhibiting...
A set of novel Donor-Acceptor-Donor (D-A-D) benzoselenadiazole derivatives has been synthesized and crystallized in nanocrystals order to explore the correlation between their chemical structure waveguided luminescent properties. The findings reveal that all crystals exhibit luminescence active optical waveguiding, demonstrating ability adjust within a broad spectral range 550–700 nm depending on donor group attached core. Notably, clear relationship exists HOMO-LUMO energy gaps each...
Formation of all-carbon-substituted quaternary carbons is a key challenge in organic and medicinal chemistry.
In order to establish a relationship between the structure and optical waveguiding behavior, two series of linear bisethynylbenzenes combining trifluoromethyl methoxy groups in core external rings were synthesized.
The recent COVID-19 outbreak has led health authorities to recommend at least the use of surgical masks, most preferably respirators (FFP2 or KN95), prevent spread virus. Non-woven fabrics have been chosen as best option manufacture face due their filtration efficiency, low cost, and versatility. Modifying mask filters with graphene great interest its potential antibacterial virucidal properties. Indeed, some companies commercialized masks in which is coated and/or embedded. However,...
A series of donor-π-acceptor-π-donor (D-π-A-π-D) compounds based on naphthalendiimide (NDI) and perylenediimide (PDI) central cores combined with triphenylamine phenylcarbazole donor groups have been synthesized, characterized tested in top-contact/bottom gate organic field-effect transistors (OFETs).
