identified key points of the material's design that influence its final photochromic functionality. We also determined for the first time a complete set of thermodynamic parameters describing thermal back-isomerization of Azo in the presence of gold and presented that application of standard Azorelated research procedures can be utilized in complex hybrid systems. This minimizes sample heating and ensures constant thermal conditions of the process (25°C). We selected 650-1100 nm spectral range (Figure ) corresponding to the position of the l-LSPR band of Au-1 plasmonic core (Figure , bottom). We carried out two types of experiments to investigate the influence of AuNRs upon red-NIR irradiation on (1) AzoGly in a form of free molecules in EtOH or (2) CNFs-bound photochrome in the hybrid materials in water.
