The continued advancement of nanostructured materials and exploitation of nanoscale size effects will ultimately require understanding material structure-property relationships at the nanoscale. Despite a plethora of metrologies capable of characterizing the thermal, mechanical, electrical, and optical properties of materials at the nanoscale, combined nanoscale chemical structure-property characterization has only recently become possible with the development of atomic force microscope based infrared spectroscopy (ARM-IR) techniques. In this regard, we have combined AFM-IR chemical structure and contact resonance AFM (CR-AFM) mechanical property measurements in the investigation of 20 – 500 nm wide fin structures fabricated in a nanoporous organosilicate material. By combining these two techniques, we have been able to clearly observe nanoscale modifications in the chemical structure and mechanical properties of the nanoporous fins that correlate with one another, the feature size, and fabrication process. This demonstration should lead the way for nanoscale chemical structure-property characterization of other materials systems where such relationships are deemed essential.
