摘要:本发明提供了一种制备特定二芳基碘化铵光引发剂的方法,该方法基于首先形成二芳基碘酸铵,该二芳基碘酸铵是从二芳基碘酸氢根的前体中形成的.然后将二芳基碘酸铵与一个反离子源(例如碱金属六氟族金属盐)反应,以产生所需的二芳基碘化铵盐,该盐可以用作光引发剂.本发明所述方法制备的碘化铵光引发剂可以用于促进各种阳离子聚合的有机材料的固化,例如环氧树脂.

摘要:Efficient method for preparing sulfonium photoacid generators (PAGs) by microwave-assisted reaction of diarylsufides in the presence of alkylaryliodonium salts. Microwave-assisted synthesis of the PAGs is significantly faster, reducing reaction time with less energy consumption. Reaction times using the microwave-assisted synthesis are in a range of from 90 to 420 faster than conventional thermal conditions. The photoacid quantum yields of several salts prepared by the microwave reaction were measured; the photoacid quantum yields of new sulfonium PAGs were in a range from 0.01 to 0.4 times greater than yields from conventional synthesis. Incorporating a nitro group in the structures of the sulfonium salts increased photoacid quantum yield, induced intersystem crossing and increased the efficiency of photoacid generation compounds.
