The novel bis-condensed heterocyclicsystems with ring assemblies based on peripheral barbituric acid rings and central pyran, pyridine and thiine rings have been generated by the reaction of terephthalaldehyde and isophthalaldehyde with barbituric acid for comparison with the analogous systems generated with said dialdehydes and 1,3-cyclohexanedione.

to initiate a ring-opening cationic photopolymerization in combination with an iodonium salt (and optionally N-vinylcarbazole) upon UV/visible light (Xe–Hg lamp; >330 nm) or visible light (halogen lamp) exposure. The structural effects in the DADs and the role of the radical cation are outlined. The cationic and radicalphotopolymerization of an epoxide/acrylate blend in a one-step hybrid cure leads
