Herein we report a covalent cage TPE-Zn_(4)based on a tetraphenylethylene molecule via subcomponent self-assembly,which is templated by zinc ***-Zn_(4)features a quadrangular prismatic cage structure,which is characterized by NMR,mass spectrum,and single-crystal X-ray ***-Zn_(4)emitted orange fluorescence(λ_(em)=620 nm)in DMSO solution under the irradiation of UV light(λ_(ex)=395 nm)and can be applied as a fluorescence sensor for selectively detecting Pd^(2+).The fluorescence of TPE-Zn_(4)was quenched by Pd^(2+)in DMSO solution,and a very low detection limit of 62.3 n M was *** studies reveal that the Pd^(2+)can replace the Zn^(2+),and the heavy atom effect and chelation-enhanced quenching effect between the Pd^(2+)and the cage probably cause the fluorescence quenching.

The equilibrium molalities of In3+ in extraction reaction: In3+(aq)+3HOx(org) = In(Ox)_3(org) + 3H+(aq) were measured at ionic strengths from 0.13 to 2.54 mol-kg~ (-1) in the aqueous phase containing Na2SO4 as the supporting electrolyte and at constant initial molality of extractant, HOx, in the organic phase at temperatures from 278.15 to 308.15 K, where HOx and Ox mean 8-hydroxy-quinoliue and its anion, respectively. The standard extraction constants K0 at various temperatures were obtained by two methods proposed in our previous paper.

In the one-color experiment at 193nm, we studied the photodissociation of Si2+ ions prepared by two-photon ionization using the time-sliced ion velocity map imaging method. The Si+ imaging study shows that Si2+ dissociation results in two distinct channels: Si(3Pg)+Si+(2Pu) and Si(1D2)+Si+(2Pu). The main channel Si(3Pg)+Si+(2Pu)) is produced by the dissociation of the Si2+ ions in more than one energetically available excited electronic state, which are from the ionization of Si2(v=0-5). Particularly, the dissociation from the vibrationally excited Si2(v=1) shows the strongest signal. In contrast, the minor Si(1D2)+Si+(2Pu) channel is due to an avoided crossing between the two 22Πg states in the same symmetry. It has also been observed the one-photon dissociation of Si2+(X4Σg-) into Si(1D2)+Si+(2Pu) products with a large kinetic energy release.

In this work,we used time-sliced ion velocity imaging to study the photodissociation dynamics of Mg O at 193 *** dissociation pathways are found through the speed and angular distributions of *** pathway is the one-photon excitation of Mg O(X^(1)∑^(+))to Mg O(G^(1)Π)followed by spin-orbit coupling between the G^(1)Π,3^(3)Πand ^(1^(5))Πstates,and finally dissociated to the Mg(^(3)Pu)+O(^(3)Pg)along the 1^(5)Π*** other two pathways are one-photon absorption of Mg O(A^(1)Π)state to Mg O(G^(1)Π)and Mg O(4^(1)Π)state to dissociate into Mg(^(3)P_(u))+O(^(3)P_(g))and Mg(^(1)S_(g))+O(^(1)S_(g)),*** anisotropy parameters of the dissociation pathways are related to the lifetime of the vibrational energy levels and the coupling of rotational and vibronic spin-orbit *** total kinetic energy analysis gives D0(Mg-O)=21645±50 cm^(-1).
