Summary: We developed a synthetic methodology for preparing (E)-1,3,6-triarylfulvenes bearing three different aryl groups. The reaction of 1,4-diaryl-1-bromo-1,3-butadienes with silylacetylenes in the presence of a palladium catalyst produced (E)-3,6-diaryl-1-silyl-fulvenes in good to excellent yields. The (isopropoxy)silylated fulvenes thus obtained were converted to (E)-1,3,6-triarylfulvenes bearing different types of aryl substituents. (E)-3,6-Diaryl-1-silyl-fulvenes are promising templates for the synthesis of diverse (E)-1,3,6-triarylfulvenes.

Summary: Seven isostructural heterometallic luminescent (Ir,Cd) coordination polymers were prepared by combining Ir (III) complexes as metalloligands with Cd (II) salts. The resulting CPs are all luminescent with emissions wavelength tunable depending on the degree of fluorination of the cyclometalating units.

Summary: Rank-reduction approaches assume that seismic data in the frequency-space domain is of low-rank after a specific pretransformation. The iterative weighted projection onto convex sets (POCS) framework can be used for noise attenuation and data reconstruction simultaneously. Multichannel singular spectrum analysis (MSSA) is a classic 3-D seismic data reconstruction algorithm that rearranges the temporal frequency slices of the data with missing traces into a block Hankel matrix and then uses randomized singular value decomposition (RSVD) to interpolate slices. To further improve the efficiency and precision of 3-D seismic data reconstruction, the fully connected tensor network (FCTN) decomposition is introduced over the Hankel tensor of the frequency slices. Our method estimates fewer parameters than MSSA and provides more accurate and robust results.

Summary: In this study, a pair of chiral Cu-I coordination polymers (1-M and 1-P) were successfully prepared by asymmetric assembly of achiral ligands and Cu2I2 clusters. These compounds exhibited dual emission bands and could be used as single-phase white-light phosphors, achieving high color rendering index and appropriate correlated color temperature. Additionally, circularly polarized luminescence signals were observed. This is the first realization of simultaneous intrinsic white-light emission and circularly polarized luminescence in coordination polymers.

Summary: Materials with aggregation-induced emission (AIE) behavior have strong emission in solid state and can respond to external stimuli, which is important for the development of materials for optical sensing, bioimaging, and optoelectronic devices. In this study, an AIE-based MOF named FJI-H31 was prepared using an AIE luminogen as the ligand. FJI-H31 showed bright luminescence under ambient conditions but no emission under vacuum. The emission intensity increased smoothly and reversibly with increased gas pressure, attributed to the restriction of intramolecular motion under pressure stimulus. Unlike most pressure-responsive MOFs, the luminescence reverted to its original state once the gas pressure recovered.
