The present invention provides compounds and compositions, 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 redical that is capable of activating chemistry; and such that compositions of matter based on the componds and compositions of the invention can be photo-patterned by one- or multiphoton excitation.
