On page 3209, Sorin Melinte, Philippe Dubois, Roberto Lazzaroni, Nicola Armaroli, and Davide Bonifazi, and co-workers present new insights into the structural and photophysical properties of porphyrin—double-walled carbon nanotube (DWCNT) hybrid materials. Contrary to previous observations in solution, the spectral features of porphyrin—nanotube derivatives recorded in the solid state show the presence J- and H-type aggregates that influence the performance of optoelectronic devices. A covalent porphyrin—nanotube hybrid promotes J-type, head-to-tale, aggregation whereas the non-covalent hybrid exhibits typical face-to-face H-type assembly.
