However, the reaction with aliphatic nitriles such as valeronitrile yielded only 10% of the desired quinazoline 23, which is a major limitation of this protocol, and thus the protocol requires further developments in substrate scope. WebPoly(trimethylsilyl styrene-b-lactide), PTMSS -b-PLA, is silicon-substituted polymer of PS-b-PLA. PTMSS-b-PLA has higher etch selectivity and higher χ (0.34) [36] than PS-b-PLA. PTMSS-b-PLA lamella normally gives parallel orientation toward substrate, therefore, solvent anneal was applied for the patterning of perpendicular lamella [36]. bk hair cut
