Provided is a compound capable of generating a Lewis acid in response to light unlike conventional photo acid generators. The compound comprises an anionic moiety having a central boron atom and a particular cationic moiety (for example, a cation having a HOMO-LUMO gap of 5.3 eV or less). The cationic moiety may, for example, have a skeleton selected from an N-substituted pyridinium skeleton, an N-substituted bipyridinium skeleton, an N-substituted quinolinium skeleton, and a pyrylium skeleton.
提供一种化合物,能够产生与传统光酸发生器不同的路易斯酸。该化合物包括具有中心硼原子的阴离子基团和特定阳离子基团(例如,具有5.3电子伏特或更低的HOMO-LUMO能隙的阳离子基团)。阳离子基团可以选择具有N-取代吡啶骨架、N-取代联吡啶骨架、N-取代喹啉骨架和吡啉骨架的骨架之一。
