Chemical infiltration during atomic layer deposition: metalation of porphyrins as model substrates.


PMID 19492376

Abstract

New uses for ALD: By applying standard metal oxide atomic layer deposition (ALD) to two types of porphyrins, site-specific chemical infiltration of substrate molecules is achieved: Diethylzinc can diffuse into the interior of porphyrin supramolecular structures and induce metalation of the porphyrin molecules from the vapor phase. A = Ph, p-HO(3)SC(6)H(4).
