“…[19,20] In turn, our recent developments in this field were aimed on the targeted introduction of various functional units to the heterocyclic fragments with special emphasis to anchoring groups. [21][22][23] Following the idea of development of cost-efficient porphyrin-based hybrid materials we considered commercially available silica as a promising inert solid support and ammonium fragment as a convenient anchoring group. Thus, in the present work we have focused on the synthesis of a new heterocycle-appended porphyrin, bearing peripheral ammonium anchoring unit (Figure 1).…”

The efficient application of the trialkylammonium group as an anchor for grafting of porphyrin to silica is demonstrated. A representative of a new series of functional porphyrins for the development of hybrid materials, namely imidazoporphyrin bearing peripheral triethylammonium unit, is synthesized. The optimal synthetic sequence towards the target type of functional derivatives is revealed. The grafting of the prepared Ni(II) porphyrin to the surface of the commercially available silica is performed and the stability of the obtained hybrid material is investigated. The loading of the porphyrin in the prepared material is evaluated as ca. 13 % by weight. The reported synthetic strategy is expected to form the basis for the development of new type of porphyrin-based hybrid materials.
