## Abstract **Summary:** We synthesized for the first time novel pHβresponsive polyampholyte microgels consisting of poly(methacrylic acid) and poly(2β(diethylamino)ethyl methacrylate) (PMAAβPDEA) that are sterically stabilized with poly(ethylene glycol) methyl ether methacrylate (PEGMEM). These mi
## Abstract **Summary:** A series of helixβcoil diblock copolymers based on poly(ethylene oxide) and optically active helical poly{(+)β2,5βbis[4β²β((__S__)β2βmethylbutoxy)phenyl]styrene} (PMBPS) were synthesized via atom transfer radical polymerization (ATRP). The synthetic methodology permitted str
A novel cyclic trimer of imidazole 1, in which imidazole rings are connected by amide bonds, has been synthesized with the help of LiCl as a template for the cyclization. The absorption spectra of 1 indicate the extension of conjugation between imidazole rings and amide bonds. The addition of 3 M eq
