Dynamic covalent bonds (DCBs), which can undergo reversible cleavage and reformation upon exposure to readily useable stimuli, have attracted dramatic attention, but the library of such bonds still remains to be developed. Herein, we report mol. structures, dynamic behaviors, and healability of bis(2,2,6,6-tetramethylpiperidin-1-yl)trisulfide (BITEMPS-S3) to compare with its disulfide analog (BITEMPS-S2) exchanged at moderate temperature Unsym. cleavage of trisulfide linkage induced relatively rapid disproportionation to di- and tetrasulfide derivatives In the bulk, poly(hexyl methacrylate) networks partially containing the BITEMPS-S3 moiety as a crosslinking point afforded nearly quant. damage healability only by simple hot pressing at 110°C under mild pressure. A slightly higher healability of BITEMPS-S2 compared to that of BITEMPS-S3 would be due to the differences in the chain-transfer reaction for the trisulfide linkage during free-radical polymerization rather than thermal exchangeability of the BITEMPS-S3 moiety. Therefore, not only BITEMPS-S2 but also BITEMPS-S3 should be regarded as one of DCBs triggered upon exposure to mild external stimuli.
2403-88-5, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., Application In Synthesis of 2403-88-5
