AbstractIn our efforts to investigate the influence of alkali-metal ions on the formation of metal complexes with polyhalogen-substituted benzenedicarboxylates, two manganese(II) complexes of tetrachlorophthalic acid (1,2-H2BDC-Cl4), [Mn2(1,2-BDC-Cl4)2(H2O)9]·H2O (1) and [MnK2(1,2-BDC-Cl4)2(H2O)4]n (2), were synthesized and structurally characterized. Single-crystal X-ray diffraction studies have revealed that complexes 1 and 2 crystallize in space groups P1̅ and Pbcn, respectively. Complex 1 shows a discrete dinuclear structure, while complex 2 features a two-dimensional heterometallic framework containing rare Mn–O–K linkages. The results clearly suggest that the introduction of alkali metal ions does play a critical role in the construction of complexes 1 and 2 with distinct dimensionality and connectivity. Their spectroscopic, thermal, and fluorescence properties have also been studied briefly.

AbstractDiffering from its bulk counterparts, atomically thin two-dimensional transition metal dichalcogenides that show strong interaction with light are considered as new candidates for optoelectronic devices. Either physical or chemical strategies can be utilized to effectively tune the intrinsic electronic structures for adopting optoelectronic applications. This review will focus on the different tuning strategies that include its physics principles, in situ experimental techniques, and its application of various optoelectronic devices.

AbstractNonlinear optical effects in layered two-dimensional transition metal chalcogenides have been extensively explored recently because of the promising prospect of the nonlinear optical effects for various optoelectronic applications. However, these materials possess sizable bandgaps ranging from visible to ultraviolet region, so the investigation of narrow-bandgap materials remains deficient. Here, we report our comprehensive study on the nonlinear optical processes in palladium diselenide (PdSe2) that has a near-infrared bandgap. Interestingly, this material exhibits a unique thickness-dependent second harmonic generation feature, which is in contrast to other transition metal chalcogenides. Furthermore, the two-photon absorption coefficients of 1–3 layer PdSe2 (β ~ 4.16 × 105, 2.58 × 105, and 1.51 × 105 cm GW−1) are larger by two and three orders of magnitude than that of the conventional two-dimensional materials, and giant modulation depths (αs ~ 32%, 27%, and 24%) were obtained in 1–3 layer PdSe2. Such unique nonlinear optical characteristics make PdSe2 a potential candidate for technological innovations in nonlinear optoelectronic devices.
