Two-Dimensional Conjugated Polymers: A New Choice For Organic Thin-Film Transistors
Chem Asian J. 2023 Dec 27:e202301076. doi: 10.1002/asia.202301076. Online ahead of print.ABSTRACTOrganic thin-film transistors (OTFTs) as a vital component among transistors have shown great potential in smart sensing, flexible displays, and bionics due to their flexibility, biocompatibility, customizable chemical structures. Even though linear conjugated polymer semiconductors are common for constructing channel materials of OTFTs, advanced materials with high charge carrier mobility, tunable band structure, robust stability, and clear structure-property relationship are indispensable for propelling the evolution of OTFTs...

Modulation of the structure-function relationship of the "nano-greenhouse effect" towards optimized supra-photothermal catalysis
Chem Asian J. 2023 Dec 28:e202301077. doi: 10.1002/asia.202301077. Online ahead of print.ABSTRACTPhotothermal catalytic CO2 hydrogenation holds great promise for relieving the global environment and energy crises. The "nano-greenhouse effect" has been recognized as a crucial strategy for improving the heat management capabilities of a photothermal catalyst by ameliorating the convective and radiative heat losses. Yet it remains unclear to what degree the respective heat transfer and mass transport efficiencies depend on the specific structures. Herein, the structure-function relationship of the "nano-greenhouse effect" was...

Synthesis and Reactivity of an Aluminium N-heterocyclic Aminal
Chem Asian J. 2023 Dec 27:e202301058. doi: 10.1002/asia.202301058. Online ahead of print.ABSTRACTTethered N-heterocyclic carbenes (NHCs) are an emerging class of ligand, as they feature all the desirable aspects of NHCs (ease of synthesis, high tunabilty) but also enable metal-ligand cooperativity when combined with Lewis acidic metal centres due to the donor-acceptor nature of the complexes formed. Herein we report a simple ethoxy-tethered NHC for the stabilisation of Al(III) hydrides, resulting in the unexpected formation of a bicyclic N-heterocyclic aminal (1). Compound 1 behaves as a metal hydride, capable of reducing ...

The Recent Advances in Iron-Catalyzed C(sp3)-H Functionalization
Chem Asian J. 2023 Dec 27:e202301056. doi: 10.1002/asia.202301056. Online ahead of print.ABSTRACTThe use of iron as a core metal in catalysis has become a research topic of interest over the last few decades. The reasons are clear. Iron is the most abundant transition metal on Earth's crust and it is widely distributed across the world. It has been extracted and processed since the dawn of civilization. All these features render iron a noncontaminant, biocompatible, nontoxic, and inexpensive metal and therefore it constitutes the perfect candidate to replace noble metals (rhodium, palladium, platinum, iridium, etc.). Moreo...

Syngas Production by Chemical Looping Dry Reforming of Methane over Ni-modified MoO3/ZrO2
Chem Asian J. 2023 Dec 25:e202301096. doi: 10.1002/asia.202301096. Online ahead of print.ABSTRACTWe investigated supported-MoO3 materials effective for the chemical looping dry reforming of methane (CL-DRM) to decrease the reaction temperature. Ni-modified molybdenum zirconia (Ni/MoO3/ZrO2) showed CL-DRM activity under isothermal reaction conditions of 650 °C, which was 100-200 °C lower than the previously reported oxide-based materials. Ni/MoO3/ZrO2 activity strongly depends on the MoO3 loading amount. The optimal loading amount was 9.0 wt.% (Ni/MoO3(9.0)/ZrO2), wherein two-dimensional polymolybdate species were dominan...

Chem Asian J. 2023 Dec 24:e202300946. doi: 10.1002/asia.202300946. Online ahead of print.ABSTRACTMetal-organic frameworks (MOFs) and their derivatives have been extensively employed in Oxygen Evolution Reaction (OER) catalysts due to their significantly larger specific surface areas, distinct metal centers, and well-organized porous structures. However, the microporous structure of MOFs and their derivatives presents mass transfer resistance, limiting their further development. Drawing inspiration from hierarchical structures allowing for the transport and exchange of substances in the biological world, we designed and fab...
