In the present article we study the generalized laws of importation and crossmigrativity based on(D, N)-implications. On the one hand, we consider the generalized law of importation I(T(x, α), y) = I(x, J(α, y)), when T is concretized as a fuzzy conjunction C, I and J are concretized as(D, N)-implications generated by a fuzzy disjunction D and a fuzzy negation N. On the other hand, we discuss the cross-migrativity of fuzzy disjunctions over fuzzy implications, that is, I(x, D(y, z)) = D(y, I(x, z)), where I is a fuzzy implication, D is a fuzzy disjunction. In addition, we study the relationship between the(α-)cross-migrative of(I, D) and the(α-)cross-law of importation(I, ID,N, C).

The dynamic first hyperpolarizabilities of a series of 1,10-phenanthroline Ru（II） complexes were carried out using density functional theory （DFT）. The results indicate that these complexes have large second-order nonlinear optical （NLO） responses. Specially, complex 6b has a maximal first hyperpolarizability βtot value. The first hyperpolarizabilities can be tuned by changing the ancillary ligand, introducing electron-acceptor group NO2 and/or increasing r-conjugation on phenanthroline. Calculations on absorption spectra demonstrate that the second-order NLO responses of complexes in series a are ascribed to the intraligand charge transfer （ILCT）, while the complexes in series b exhibit metal-to-ligand charge transfer （MLCT） and lig- and-to-ligand charge transfer （LLCT） transition at relatively low-energy absorptions.

Chemical functionalization of fullerenes has been an important topic in fullerene chemistry. Herein, an unprecedented Pd-catalyzed migration reaction of [60]fullerene with allyloxy-tethered aryl iodides is present for the preparation of novel [60]fullerene-fused allylbenzofurans. The use of 1,2-bis(diphenylphosphino)benzene (DPPBz) as a ligand is crucial for the success of the transformation. The reaction shows high chemo- and regioselectivity, and is flexible with regard to allyl-migration site, providing a new and efficient approach to rare [60]fullerene-fused benzofurans. Control experiments disclose that the reaction most probably undergoes a sequential C—O bond cleavage/allyl-migration/intermolecular cycloaddition cascade process.

In this work, density functional theory (DFT) combined with the finite field (FF) method has been adopted to analyze the second-order nonlinear optical (NLO) properties of the triarylborane (TAB) derivatives obtained by introducing different inductive electron groups into the phenylene ring of the TAB (RTAB, where R=2-C6H5-C2B10H10(1),R=F(2), R=Me(3),R=NO2(4),R=NH2(5)). The static first hyperpolarizabilities (βtot) of the RTAB molecules can be switched by binding one F- to the boron center (RTAB′) or one-electron reduction (RTAB"). The DFT-FF calculations show that the βtot values of 2′, 3′ and 5′ decrease while those of 1′ and 4′ increase compared with the values of their neutral molecules, which was attributed to the fact that the charge transfers of 2, 3 and 5 become smaller and those of 1 and 4 become larger by binding one F- ion to the boron center, according to time-domain DFT (TD-DFT) analysis. However, the incorporation of one electron enhances the second-order NLO properties of the RTAB molecules remarkably, especially for system 1. It is notable that the βtot value of reduced form 1″ is 508.69×10-30 esu, i.e. about 578 times larger than that of system 1. Frontier molecular orbital (FMO) and natural bond orbital (NBO) analyses suggest that the reversal of the charge distribution between the neutral molecules and their reduced forms leads to low HOMO-LUMO energy gaps (E0) and thus large βtot values for the reduced forms.
