Convex-concave stacking of curved conjugated networks: Benchmark calculations on the corannulene dimer

► A binding energy for corannulene dimer was calculated at QCISD(T)/aug-cc-pVTZ level. ► Dispersion-corrected DFT functionals were tested using the benchmark results. ► Several structural motifs of the dimer were studied at B97-D/cc-pVQZ level. ► Efficiency of the dispersion attraction of curved carbon networks was assessed.
