Synthesis of porphyrinoids with silane anchors and their covalent self-assembling and metallation on solid surface

► Porphyrinoids with silane anchor prepared with high yield by hydrosilylation. ► Reduction side reaction suppressed by proper choice of catalyst. ► Compounds are stable yet reactive, isolated in pure form, have good shelf life. ► Chromophores form SAM on oxide surfaces and optical fibers with ease in one step. ► Method can be applied to virtually any chromophore with hydroxy groups.
