- •
The infrared spectra of 1,4-phenylene diisocyanide (PDI) on gold films show a free isocyanide mode at high PDI solution doses.
- •
Dosing gold-nanoparticle covered mica with PDI shows an initial increase and then a decrease in conductivity.
- •
The results show a conversion from flat-lying Au–PDI oligomers to a vertical species with increasing dose.
- •
The results rationalize the apparent discrepancy with previous work.
