Wallraff, G. M. published the artcileSynthesis and lithographic performance of photosensitive poly(phenylquinoxaline)s and related structures, Synthetic Route of 18512-55-5, the publication is Polymeric Materials Science and Engineering (1992), 289-90, database is CAplus.
Two new photoimageable dielecs. are demonstrated which are based on poly(quinoxalone) (PPQ) and poly(phenylquinoxaline) using a chem. amplification scheme. The PPQ was shown to be a high contrast system and both systems were photodefinable at 514 and 426 nm, affording neg.-tone images. The extent of butyloxycarbonyl (BOC) cleavage was relatively low (<40%) compared to styrene-BOC systems presumably due to the presence of basic nitrogens in the heterocyclic backbone.
Polymeric Materials Science and Engineering published new progress about 18512-55-5. 18512-55-5 belongs to naphthyridine, auxiliary class Alkynyl,Anthracene, name is 9,10-Diethynylanthracene, and the molecular formula is C12H14IN, Synthetic Route of 18512-55-5.
