This paper presents the synthesis and structural characterization of asymmetrictripyrrane-containing macrocycle.This macrocycle could be oxidized to the methine
β-(2-imidazolinyl)-ethyl methyl diethoxy silane quarternary halides and its condensed polymers with bisphenol A were synthesized and characterized. The polycat
