In State-I, a mixture comprising a DABCO-bridged tris(zinc-porphyrin) double decker and a free biped (=slider), catalysis was OFF. Acid addition (TFA or Di-Stefano fuel acid) to State-I liberated DABCO-H+ while generating a highly dynamic slider-on-deck device (State-II). The released DABCO-H+ acted as a base organocatalyst for a Knoevenagel reaction (catalysis ON). The system was reversed to State-I (catalysis OFF) by reducing the acidity in the system (by adding DBU or via the fuel-derived base). In the experiment, the researchers used 4-Ethynylpyridine(cas: 2510-22-7Safety of 4-Ethynylpyridine)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Safety of 4-Ethynylpyridine
