Nanometrology assisted chemical fabrication: direct laser writing of porphyrins onto complex surfaces

Year: 2025

Type: article

Abstract: optical monitoring is used to non-invasively analyze their grafting behavior in different conditions, optimizing the reaction and enabling modification of inert glass surfaces with high precision (30 atto L). We demonstrate that the methodology is compatible with direct laser writing technologies, and use it to prepare photophysically active surfaces with high resolution. We demonstrate that the instrinsic emissive properties of Tetraphenylporphyrin derivatives are well preserved, and that several surface modifing steps can be sequentially stacked, leading to the preparation of surfaces with multiple functions. By controlling the microscale distribution of chemical groups with different photophysical properties, we demonstrate that complex chemical designs can be readily and reliably implemented. This work therefore shows that light activated radical pathways can be broadly used to modify surfaces, opening interesting new perspectives for the implementation of functional materials.
