Abstract: Highlights: [•] Importance of 1H-2(Phenylazo) imidazole (PaiH) molecule is discussed. [•] Interaction of PaiH with silver nano particles is possibly through theN3 atom. [•] Concentration dependent dark isomerisation (trans-to-cis) is suggested. [•] DFT calculations are in good agreement with experimental results. [ABSTRACT FROM AUTHOR]
