Thin film synthesis of hybrid ultramicroporous materials (HUMs)- a comparative approach

Abstract

The thin-film synthesis of the hybrid ultramicroporous material (HUM) TIFSIX-3-Ni on glass substrates are reported for the first time. Several methods of film formation are employed including dip-coating, seeding and secondary growth, vapour-assisted conversion, rapid thermal deposition and in-situ coating. Using the in-situ approach with dimethylformamide as solvent, we were able to grow homogeneous TIFSIX-3-Ni films at relatively low temperatures (85 °C) and short times (5 h) without substrate modification. During this study, we also significantly reduced the TIFSIX powder synthesis time to 15 h.
