Synthesis and reactions of indane‐1,3‐dione‐2‐thiocarboxanilides with hydrazonoyl halides and active chloromethylene compounds [PDF]
Heteroatom Chemistry, 2002 AbstractA novel synthesis of thiadiazoline derivatives 12 and 14 via treatment of indane‐1,3‐dione‐2‐thiocarboxanilides (5) with hydrazonoyl halides 1 and 2 is reported. Also, active chloromethylene compounds 15 react with 5 to give thiazole derivatives 19. © 2002 Wiley Periodicals, Inc.

Lattice compression increases the activation barrier for phase segregation in mixed-halide perovskites [PDF]
arXiv, 2020 The bandgap tunability of mixed-halide perovskites makes them promising candidates for light emitting diodes and tandem solar cells. However, illuminating mixed-halide perovskites results in the formation of segregated phases enriched in a single-halide. This segregation occurs through ion migration, which is also observed in single-halide compositions,

A thermodynamic band gap model for photoinduced phase segregation in mixed-halide perovskites [PDF]
arXiv, 2023 Provided is a comprehensive description of a band gap thermodynamic model, which predicts and explains key features of photosegregation in lead-based, mixed-halide perovskites. The model provides a prescription for illustrating halide migration driven by photocarrier energies. Where possible, model predictions are compared to experimental results. Free

Orbital Engineering in Three Dimensional Halide Perovskites towards Two Dimensional Properties with Strong Anisotropy [PDF]
J. Phys. Chem. Lett. 2019, 2019 The discovery of double perovskites A2B(I)B(III)X6 (A=monovalent cation; B(I)/B(III) = metal cation; X = halogen) as Pb(II)-free alternatives has attracted widespread attention, making it possible to introduce d-block metal cations (e.g., d0 and d10) into halide perovskites.
