Compounds of formula (I) are disclosed.  The tetrapyrole ring in formula (I) can be substituted with a metal cation (M); R, R, Rand Rseparately represent a hydrogen atom, a C1-4 alkyl or alkyloxy radical, or a phenyl radical optionally substituted by vinyl, hydroxy, nitro, amino, bromo, chloro, fluoro, iodo, benzyloxy, or hydroxymethyl radicals; R, R, Rand Rseparately represent a hydrogen atom or a C1-4 alkyl radical; R, Rand Rseparately represent a hydrogen atom, a C1-4 alkyl or alkyloxy radical optionally substituted by a halogen, or a phenyl radical optionally substituted by vinyl, hydroxy, nitro, amino, bromo, chloro, fluoro, iodo, benzyloxy, or hydroxymethyl radicals, wherein at least one of R, R, and Ris a phenyl radical. Compounds of formula (I) bound to a silica, a sol-gel material or a mesoporous silica are useful for selective trapping of carbon monoxide.
