General Description

Tert-butyl (2-(thiophen-2-yl)ethyl)carbamate is a chemical compound with a molecular formula of C12H19NO2S. It is a carbamate derivative that is commonly used as a protecting group in organic synthesis. tert-butyl (2-(thiophen-2-yl)ethyl)carbamate is characterized by a tert-butyl group attached to a carbamate group, which in turn is connected to a thiophen-2-yl moiety through an ethyl spacer. Tert-butyl (2-(thiophen-2-yl)ethyl)carbamate is often employed as a temporary protecting group for amines and alcohols, providing stability to these functional groups during various synthetic reactions. Additionally, this compound's unique structure containing a thiophene ring makes it useful in medicinal chemistry as a potential bioactive scaffold for drug development.

Direct-Bandgap 2D Silver-Bismuth Iodide Double Perovskite: The Structure-Directing Influence of an Oligothiophene Spacer Cation

Three-dimensional (3D) hybrid organic-inorganic lead halide perovskites (HOIPs) feature remarkable optoelectronic properties for solar energy conversion but suffer from long-standing issues of environmental stability and lead toxicity. Associated two-dimensional (2D) analogues are garnering increasing interest due to superior chemical stability, structural diversity, and broader property tunability. Toward lead-free 2D HOIPs, double perovskites (DPs) with mixed-valent dual metals are attractive. Translation of mixed-metal DPs to iodides, with their prospectively lower bandgaps, represents an important target for semiconducting halide perovskites, but has so far proven inaccessible using traditional spacer cations due to either intrinsic instability or formation of competing non-perovskite phases. Here, we demonstrate the first example of a 2D Ag-Bi iodide DP with a direct bandgap of 2.00(2) eV, templated by a layer of bifunctionalized oligothiophene cations, i.e., (bis-aminoethyl)bithiophene, through a collective influence of aromatic interactions, hydrogen bonding, bidentate tethering, and structural rigidity. Hybrid density functional theory calculations for the new material reveal a direct bandgap, consistent with the experimental value, and relatively flat band edges derived principally from Ag-d/I-p (valence band) and Bi-p/I-p (conduction band) states. This work opens up new avenues for exploring specifically designed organic cations to stabilize otherwise inaccessible 2D HOIPs with potential applications for optoelectronics.

A selenophene-containing conjugated organic ligand for two-dimensional halide perovskites

A selenophene-containing conjugated organic ligand, 2-(4′-methyl-5′-(5-(3-methylthiophen-2-yl)selenophen-2-yl)-[2,2′-bithiophen]-5-yl)ethan-1-aminium (STm), was synthesized and incorporated into a Sn(ii)-based two-dimensional perovskite, (STm)2SnI4. The band offset between the perovskite and ligand can be fine-tuned by introducing the STm ligand. Both field-effect transistor and light-emitting diode devices based on (STm)2SnI4films exhibit high performance and enhanced operational stability.
