The results on zirconia-amine bifunctional modification of hierarchically porous silica monoliths for continuous-flow processes ar presented. The study reports the synthesis and properties of the modified porous monoliths and their performance in the tandem process of deacetalization-Knoevenagel condensation reaction. The properties of the materials were studied by thermal analysis, FTIR spectroscopy, XRF and nitrogen adsorption.

- A series of thiophene-based azomethines with varying core structures were synthesized and analyzed for their thermal, optical, and electrochemical properties.
- The compounds showed high glass transition temperatures and were electrochemically active with a low energy band gap below 1.7 eV, indicating promising performance in electronic applications.
- When tested as hole transporting materials in solar cells, the imines demonstrated improved power conversion efficiency, particularly those with a core tiphenylamine structure, achieving 35-63% better performance than other configurations.
