  abstract  = {A new series of [Pd2(L)4] cages based on photochromic dithienylethene (DTE) ligands allowed us to gain insight into the successive photoswitching of multiple DTE moieties in a confined metallo-supramolecular assembly. Three new X-ray structures of [Pd2(o-L4)4], [Pd2(o-L1)2(c-L1)2] and [Pd2(c-L1)4] (o-L and c-L = open and closed forms of DTE ligands, respectively) were obtained. The structures deliver snapshots of three different combinations of DTE photoisomeric states within the cage, facilitating a comparison of the all-open with the all-closed, and most notably, an intermediate form where open and closed switches co-exist in the same cage. Moreover, a series of spherical anionic borate clusters was introduced in order to study their roles in the light-controllable host-guest chemistry. The binding guests show higher affinities with the flexible open cage [Pd2(o-L1)4] than with the rigid closed cage [Pd2(c-L1)4]. For the [B12F12]2- guest, thermodynamic data obtained from NMR experiments was compared to results from isothermal titration calorimetry (ITC).},
