Aerogel based on nanoporous aluminium ferrocenyl diphosphinate metal-organic framework

Abstract

New porous coordination polymer (PCP) has been synthesized using ferrocene-based ligand bearing phosphinic groups (H2fcdHp = 1,1′-ferrocenediyl-bis(H-phosphinic acid)) and aluminum salt. Al-fcdHp was obtained according to a sol–gel approach followed by supercritical CO2 drying. The N2 adsorption properties of aerogel were investigated and N2 amount adsorbed in the pores of PCP reaches 1400 cm3g−1. The aerogel exhibits high surface area of approximately 671 m2/g and redox activity due to ferrocenyl fragment.
