“…Apart from Te 4 2+ , which proves a dominance in Lewis-acidic AlCl 3 -containing ILs similar to Bi 5 3+ , several other tellurium polycations (Figure 5) were accessed in ILs [26,27,31,101,102,103]. Thereby, the utilization of an IL as reaction medium can lead to extraordinary properties of the reaction product as the following example demonstrates: Te 4 [Bi 0.67 Cl 4 ] obtained from a gas-phase transport reaction is an conventional semiconductor.…”

Ionic liquids (ILs) have been proven to be valuable reaction media for the synthesis of inorganic materials among an abundance of other applications in different fields of chemistry. Up to now, the syntheses have remained mostly “black boxes”; and researchers have to resort to trial-and-error in order to establish a new synthetic route to a specific compound. This review comprises decisive reaction parameters and techniques for the directed synthesis of polyions of heavy main-group elements (fourth period and beyond) in ILs. Several families of compounds are presented ranging from polyhalides over carbonyl complexes and selenidostannates to homo and heteropolycations.

“…Ionic liquids expand the synthetic potential of the widely used AlCl 3 based melts due to the low reaction temperatures and their high ionicity. This allowed for the isolation of the first superconducting polycation containing phase (Te 4 )[Bi 0.74 Cl 4 ]2 or expanded nets of cations as present in (Te 8 ) 2 [Ta 4 O 4 Cl 16 ] 3…”

Adaptation of simple molecular networks to time‐dependent stimulus

Adaptation is the ability by which signaling systems reset themselves after responding to a stimulus. Incoherent feedforward loops and negative feedback loops are the only two types of three‐node topologies showing adaptation to constant stimuli. In this study, adaptation of these two types of topologies to time‐dependent stimuli are discussed. Through analytical calculation and numerical simulations, it is found that they may show adaptation when the pulse duration and internal are properly assigned. In particular, for incoherent feedforward loops, two kind of models, i.e., logic approximation piecewise‐linear equations and Hill‐type equations are considered. When adaptation to time‐dependent stimulus is considered, analytical solutions for logic approximation piecewise‐linear equations and numerical simulation for Hill‐type equations are in substantial agreement. The study on adaptation to time‐dependent stimulus could serve as a manual providing different possible solutions to develop intelligent therapeutic strategies and to build biological circuits with specified functions.
