Osuka* π-Conjugation Enlargement Toward the Creation of Multi-Porphyrinic Systems with Large Two-Photon Absorption Properties Arrays the way! Recent progress in the synthesis of covalently linked porphyrin arrays with large two-photon absorption (TPA) cross-section values has been reviewed with a particular focus on the relation of TPA properties with molecular structures. This will help understand the structural requirements of porphyrin arrays with large TPA values, which will be useful for future applications in optical communication in the IR region. Chem. Asian J.
