From Molecular Photochemistry to Supramolecular Photochemistry: A Paradigm for the 1990s

The paradigm of molecules and the covalent bond between atoms has been a powerful and unifying principle for chemistry and photochemistry for decades. We now consider a "paradigm shift" which has been occurring during the past two decades and which may take its place along side the molecular paradigm during the 1990s, namely, the paradigm of supramolecular chemistry
