The green solvent: a critical perspective

Clean Technologies and Environmental Policy, Journal Year: 2021, Volume and Issue: 23(9), P. 2499 - 2522

Published: Sept. 30, 2021

Abstract Solvents are important in most industrial and domestic applications. The impact of solvent losses emissions drives efforts to minimise them or avoid completely. Since the 1990s, this has become a major focus green chemistry, giving rise idea ‘green’ solvent. This concept generated substantial chemical literature led development so-called neoteric solvents. A critical overview published material establishes that few new materials have yet found widespread use as search for less-impacting solvents is inefficient if carried out without due regard, even at research stage, particular circumstances under which be used on scale. Wider sustainability questions, particularly non-fossil sources organic carbon manufacture, more than intrinsic ‘greenness’. While solvency universal, universal solvent, an alkahest, unattainable ideal.

Extensive Screening of Green Solvents for Safe and Sustainable UiO-66 Synthesis

ACS Sustainable Chemistry & Engineering, Journal Year: 2020, Volume and Issue: 8(46), P. 17154 - 17164

Published: Nov. 11, 2020

Zirconium based metal–organic framework UiO-66 is to date considered one of the benchmark compounds among stable MOFs, and it has attracted huge attention for its employment in many strategic applications. Large scale production industrial purposes requires use safe green solvents, fulfilling chemistry principles able replace N,N-dimethylformamide (DMF), which, despite toxicity, still most efficient solvent obtaining high quality. Herein we report on a survey about 40 different solvents with polarities, boiling points acidities, used laboratory synthesis quality crystals. The were chosen according European REACH Regulation 1907/2006 those having low cost toxicity being fully biodegradable. Concerning MOF synthesis, relevant parameters establishing results obtained are degree crystallinity, microporosity, specific surface area, yield, recyclability. Taking into account also chemical physical properties all color code was assigned order give final assessment synthesis. Defectivity products, acidic modulators, alternative Zr salts have been taken consideration. Preliminary lead conclusion that GVL (γ-valerolactone) promising replacing DMF

Abstract Intelligent objects, autonomous factories and humans browsing the real world with artificial technology‐based capabilities is not movie set of a new saga but what going to happen next‐generation electronics bioelectronics fabricated emerging materials, technologies, devices. The emergence (bio)electronics as ubiquitous feature an advanced modern society posing challenge managing ever‐increasing amount e‐waste, also making recovery more difficult. Thus, design approaches are required considering that possibly small significant fraction mass‐scale e‐products inherently impossible recover. In this perspective, organic materials technologies can provide important solutions. This review presents analyses green underpinning development sustainable transistors, which promise become key components for Earth‐safe wide‐spread bioelectronics.

Toward High Mobility Green Solvent‐Processable Conjugated Polymers: A Systematic Study on Chalcogen Effect in Poly(Diketopyrrolopyrrole‐alt‐Terchalcogenophene)s

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(38)

Published: July 3, 2021

Abstract Nine diketopyrrolopyrrole (DPP)‐based conjugated polymers (CPs), that is, poly(diketopyrrolopyrrole‐ alt ‐terchalcogenophene)s, via combinations of furanyl‐(FDPP), thienyl‐(TDPP), selenophenyl‐DPP (SeDPP) and furan, thiophene, selenophene comonomers, are synthesized to explore the chalcogen effect on solubility, film morphology/microstructure, charge transport property resultant polymers. All except for SeDPP‐Se soluble in non‐chlorinated solvents such as o ‐xylene tetralin. Flanking DPP with furan FDPP‐F, FDPP‐T, FDPP‐Se enables even good solubility green solvent anisole. TDPP‐Se exhibits highest reliable hole mobility over 10 cm 2 V −1 s organic thin transistors (OTFTs) bar‐coated from ‐xylene/tetralin (20/80 v/v) solution. With anisole processing solvent, FDPP‐F‐based OTFTs displays a up 3.50 . This is first report processed above 1 Charge all correlated morphology microstructure noticeably influenced by type position chalcogenophenes. The current work sheds light design high CPs processable solvents.

Foundry-compatible high-resolution patterning of vertically phase-separated semiconducting films for ultraflexible organic electronics

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Aug. 16, 2021

Abstract Solution processability of polymer semiconductors becomes an unfavorable factor during the fabrication pixelated films since underlying layer is vulnerable to subsequent solvent exposure. A foundry-compatible patterning process must meet requirements including high-throughput and high-resolution patternability, broad generality, ambient processability, environmentally benign solvents, and, minimal device performance degradation. However, known methodologies can only very few these requirements. Here, a facile photolithographic approach demonstrated for p- n-type semiconducting polymers. This involves crosslinking vertically phase-separated blend UV photocurable additive, enables processable photopatterning at resolutions as high 0.5 μm in three steps with solvents. The patterned be integrated into thin-film transistors having excellent transport characteristics, low off-currents, thermal (up 175 °C) chemical (24 h immersion chloroform) stability. Moreover, organic structures also on 1.5 μm-thick parylene substrates yield highly flexible (1 mm radius) mechanically robust (5,000 bending cycles) transistors.
