Organic nanocrystals of [2.2]paracyclophanes achieved via sonochemistry: Enhanced and red-shifted emission involving edge-to-face chromophores

Article abstract of DOI:10.1039/c2ce26000j

We have prepared organic nanocrystals of [2.2]paracyclophane (pCp) and tetrakis(4-pyridylcyclobutyl)[2.2]paracyclophane (tpcp) via sonochemistry. Both nanocrystals exhibit an enhanced fluorescence compared to dilute solution, while the tpcp nanocrystals also demonstrate a red-shifted fluorescence.
