“…Jia et al indicated that metals with different radii can have various application prospects in third-order nonlinear materials . Zhang et al reported the NLO properties of fulvalene Ru 2 -linked POM, in which the NLO response is enhanced by introducing an electron-donating group (NH 2 ) . The contribution of heavy-metal ions to the third-order NLO characteristics is very considerable in metal clusters, permitting more allowed electronic transitions because of the introduction of additional sublevels in the energy hierarchy, thus generating greater NLO effects .…”

For the advancement of laser technologies and optical engineering, various types of new inorganic and organic materials are emerging. Metal−organic frameworks (MOFs) reveal a promising use in nonlinear optics, given the presence of organic linkers, metal cluster nodes, and possible delocalization of π-electron systems. These properties can be further enhanced by the inclusion of solely inorganic materials such as polyoxometalates as prospective low-cost electron-acceptor species. In this study, a novel hybrid nanocomposite, namely, SiW 12 @NU-1000 composed of SiW 12 (H 4 SiW 12 O 40 ) and Zrbased MOF (NU-1000), was assembled, completely characterized, and thoroughly investigated in terms of its nonlinear optical (NLO) performance. The third-order NLO behavior of the developed system was assessed by Z-scan measurements using a 532 nm laser. The effect of two-photon absorption and self-focusing was significant in both NU-1000 and SiW 12 @NU-1000. Experimental studies suggested a much superior NLO performance of SiW 12 @NU-1000 if compared to that of NU-1000, which can be assigned to the charge-energy transfer between SiW 12 and NU-1000. Negligible light scattering, good stability, and facile postsynthetic fabrication method can promote the applicability of the SiW 12 @NU-1000 nanocomposite for various optoelectronic purposes. This research may thus open new horizons to improve and enhance the NLO performance of MOF-based materials through π-electron delocalization and compositing metal−organic networks with inorganic molecules as electron acceptors, paving the way for the generation of novel types of hybrid materials for prospective NLO applications.

“…11,15 Switchable SHG materials have great potential for applications in optical switches, biosensors, and data storage. [30][31][32] High-quality SHG materials are generally stable in perform-ance, and exhibit a lack of symmetry centers on the basis of the structural phase transitions. [33][34][35][36] As far as we know, hostguest crown ether inclusions with structural phase transitions can easily change the spatial structure under external temperature stimulation as their atomic positions can move from one equilibrium to another.…”
