The tunable inorganic nodes and modifiable organic linkers enable the designable functionality to come true in the new-type porous hybrid materials, namely metal-organic frameworks (MOFs). By using viologen-functionalized mbenzenedicarboxylate as organic linker, a terbium-organic framework embedded with asymmetric viologen species has been constructed. The reversible photochromism from bright yellow to dark green is implemented due to favorable spatial stack of the electron donor and acceptor. The photochromic component of the organic linkers can modulate the luminescence of tetranuclear terbium cluster under irradiation of UV light, which is defined as photoluminescence switch behavior. The different protonation levels of uncoordinated N atoms with varying pH enable the MOF as a potential fluorescent pH sensor. Thus, multi-photofunctionality, viz. photoluminescence, photochromism as well as the derivate fluorescent response to irradiation and pH have been combined in the Tb-MOF, which is the first example in the viologen-based photochromic hybrid materials.

The oil–water separation has attracted heightened attention because of the ever‐increasing amounts of oily water produced from the daily activities of humans and industrial processes. Membrane technology as an advanced water purification approach has offered an indispensable option due to its cost‐effective, energy‐efficient, and easy‐to‐operate characteristics. However, traditional membrane materials suffer from severe fouling, which counteracts the superiority of applying membranes in oil–water separation applications. Thanks to the emerging bioinspired interface research, a series of special wettability not only endows membrane surfaces with outstanding antifouling properties but also breaks though the long‐standing tradeoff effect between membrane permeability and selectivity. In this review, the recent advances of membranes used for oil–water separation with special wettability and perspectives on the on‐going research are presented. The authors first discuss the wetting phenomenon on membrane surface, and then highlight the gradually evolved specially wettable system and its coupling with membrane materials. Next, relatively comprehensive preparation methods and applications of oil–water filtration membranes utilizing special wettability are summarized. Finally, the authors conclude the current achievements and challenges in specially wettable membranes for oil–water separation and outlook the future in this field.

The field of entrepreneurship is considered essential for the economy, and many researchers around the world have studied it from diverse perspectives. The outcomes of this research are not yet consensual. Today, it is gaining attention and consensus due to the increasing pressure of sustainable development, so there is a need for academic research to examine this field by incorporating sustainability value creation practices and the efforts of current entrepreneurs towards said goal, especially in the case of the agricultural sector. Accordingly, this study aims to address the problem of what drives students to incorporate sustainable agriculture in their entrepreneurial ventures. Moreover, we aim to determine whether the value placed in the triple bottom line affects the intention to establish sustainable businesses. The study is based on five antecedents of the Theory of Planned Behavior (TBP) and was designed to explore the mechanism underlying the intention to promote sustainable entrepreneurship in agriculture. The primary objective was to collect and analyze the data using the partial least square structural equation model (PLS-SEM) to test the determinants. The results revealed that the indicators of a favorable sustainable attitude, supportive subjective norms, control behaviors, adequate opportunity recognitions, and encouraging the triple bottom line had strong influences on the intention of promoting sustainability in entrepreneurship. Besides, the attitudes, subjective norms, opportunity recognition, and sustainability values can also predict students’ significant positive intentions toward sustainable agriculture in entrepreneurship. The research findings contribute to the literature by providing an empirical basis for the formulation of policies to encourage students to start an agribusiness, thereby improving the effectiveness of entrepreneurship education development programs and bridging the gap between sustainable entrepreneurial intentions and actions. Therefore, the insight into the determinants of sustainable entrepreneurship can be an essential step toward designing a practical and durable policy mechanism for the implementation of the triple bottom line when developing entrepreneurial agriculture education programs.

A new bidentate "building block", N, N′-bis(3-pyridylformyl)piperazine (bpfp), was synthesized. X-ray diffraction studies reveal that the piperazine ring in bpfp forms a chairlike structure conformation. bpfp self-assembled into two-dimensional layered rhombohedral grid polymers {[Mn(H2O)2-(SO4)(bpfp)](H2O)3(CH3OH)}n (1) and {[Zn(NCS)2(bpfp)2]‚2H2O}n (2) with Mn(II) and Zn(II), a threedimensional polymer [Cd(N3)2(bpfp)]n (3) with Cd(II), and a one-dimensional zigzag polymer [HgI2(bpfp)]n (4) with Hg(II). Each rhombohedral grid in polymer 1 is composed of four Mn, two bpfp, and two SO4 2-; the dimensions of the grid are 6.537 × 12.843 Å. In polymer 2, each rhombohedral grid consists of 60membered rings Zn4(bpfp)4 showing the dimensions of 14.231 × 15.586 Å. Zn4(bpfp)4 grids are bridged by Zn ions and all pyridyl-N atoms of bpfp ligands into the 2-D network structure along a and c directions. Polymer 3 exhibits a 3-D layered structure with tetragonal prism channel viewing from a direction. The bpfp ligands occupy the four edges of tetragonal prism channel, which is cut off by layers consisting of rhombohedral grids Cd 4(N3)4. Polymer 4 is quite different from polymers 1-3; it exhibits a 1-D zigzag framework extending along the c axis. Polymers 1-3 possess a very strong NLO absorption and selffocusing effect. Their third-order NLO absorptive coefficients R2 are 9.2 × 10 -9 , 6.9 × 10 -9 , and 7.1 × 10 -9 m W -1 . The third-order NLO hyperpolarizabilities γ are 1.79 × 10 -28 , 9.10 × 10 -29 , and 9.66 × 10 -29 esu, respectively. The γ values are comparable to those of the best NLO materials and coordination polymers. We found that the valence shell structures of central metal ions can influence the NLO properties of coordination polymers.
