A chiral vanadyl phthalocyanine formed helical aggregates with a left-handed helix sense; the aggregates showed an efficient third harmonic generation in as-prepared films and the χ(3) value was enhanced by the chiral aggregation with reference to a mixture of racemic diastereoisomers.
一种手性钒酞菁形成了左手螺旋感的螺旋聚集体;这些聚集体在制备的薄膜中显示出有效的三次谐波产生,且与外消旋二元体的混合物相比,手性聚集增强了χ(3)值。
