A panchromatic modification of the light absorption spectra of metal-organic frameworks
The optical absorption of UiO-66-NH 2 MOF was red-shifted using a diazo-coupling reaction. The modifications performed with naphthols and aniline yielded reddish samples, and the modifications with diphenylaniline yielded dark violet ones. The photocatalytic activity of these modified MOFs was asses...

MOF was red-shifted using a diazo-coupling reaction.

. The degradation performance was found to correlate with the red shift of the absorption edge. These findings suggest potential applications of these materials in photocatalysis and in dye sensitized solar cells.
Zr-based MOFs' light absorption spectra were shifted from UV to NIR
via
diazo coupling reaction. The photocatalytic performance of the solids was correlated with absorption edge. |
