dc.description.abstract | The use of chemical messengers to control multiple and often disparate downstream events is a hallmark of biological signaling. Here, we report a synthetic supramolecular construct that gives rise to bifurcated downstream events mediated by different stimulus-induced chemical messengers. The system in question consists of a supramolecular redox-ensemble made up of a tetrathiafulvalene (TTF)-based macrocycle, benzo-TTF-calix[4]pyrrole, and an electron deficient partner, 7,7,8,8-tetracyanoquinodimethane (TCNQ). Different tetraalkylammonium halide salts are used to trigger the reversible switching between neutral (No-ET), charge transfer (CT), and electron transfer (ET) states. The result is an effective tristate switch that provides chemical access to three different forms of TCNQ, namely, a released neutral, radical anionic (TCNQ(center dot-)), or bound CT forms. The ionically induced switching chemistry is linked separately through the neutral and radical anion TCNQ forms to two distinct follow-on reactions. These reactions consist, respectively, of styrene polymerization, which is triggered only in the "1" (TCNQ radical anion ET) state, and a cycloaddition-retroelectrocyclization (CA-RE) reaction, which is mediated only by the neutral TCNQ "0" (No-ET) state. Neither downstream reaction is promoted by the CT form, wherein the TCNQ is receptor bound. The three states that characterize this system, their interconversion, and the downstream reactions promoted by TCNQ(center dot-) and free TCNQ, respectively, have been characterized by single-crystal X-ray diffraction analyses and various solution phase spectroscopies. | - |
