The invention relates to a method suitable for detecting, capturing and/or selectively releasing chemical elements selected from poor metals, alkalines, alkaline earths, actinides and rare earths. Said method involves a molecular assembly formed by at least one amine, and at least one aldehyde and/or an imine and/or CO, or an adduct formed by the contact between an amine and CO, and at least one of said chemical elements. The invention also relates to a kit for implementing said method for detection, capture and/or release.

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.
