Experimental and Computational Dataset for a Spiro-Centered Poly(benzimidazole) with Intrinsic Microporosity (STATA-PIM): Synthesis, Characterization, Molecular Modeling and Gas Adsorption

This repository contains the complete experimental and computational dataset supporting the study on a spiro-centered poly(benzimidazole) with intrinsic microporosity (STATA-PIM). The dataset includes: • Raw and processed ATR-FTIR spectra.• X-ray diffraction (XRD) data.• Thermal analysis (TGA, DTG and DSC).• Gas adsorption measurements (H2, CO2, CH4 and N2).• Molecular modeling data obtained using HyperChem, including optimized structures, interaction energies and pore geometry analyses.• Source data used for figures and tables.• Supporting Information associated with the manuscript. These files allow complete reproducibility of the analyses reported in the accompanying publication.
