WebNov 11, 2012 · We have introduced a series of nonionic photoacid generators (PAGs) for carboxylic and sulfonic acids based on N-hydroxyanthracene-1,9-dicarboxyimide (HADI). The newly synthesized PAGs exhibited positive solvachromatic emission (λmax(hexane) 461 nm, λmax(ethanol) 505 nm) as a function of solvent polarity. Irradiation of PAGs in acetonitrile … WebOur photo acid generator product line has proven quality and performance for excimer resist applications with industry leading resist manufactures. Besides the products listed below, … can fish chowder be frozen made with milk
