The present invention provides compounds and compositions, including a selenonium or sulfonium group, which include; at least one chromophore having strong simultaneous two-photon or multi-photon absorptivity; at least one acid- or radical-generator in close proximity to the chromophore; such that the single- or multi-photon excitation of the chromophore results in the generation of an acid and/or radical that is capable of activating chemistry; and such that compositions of matter based on the compounds and compositions of the invention can be photo-patterned by one- or multi-photon excitation.
本发明提供了包括硒基或锍基团的化合物和组合物,其中包括:至少一个具有强同步双光子或多光子吸收性的发色团;至少一个靠近发色团的酸或自由基发生器;这样,发色团的单光子或多光子激发会导致产生能够激活化学反应的酸和/或自由基;并且,基于本发明化合物和组合物的物质组合物可以通过单光子或多光子激发进行光图案化。
