Perylene bisimide (PBI) derivatives with various alkynyl–phenyl substituents at a single bay position have been synthesised by Sonogashira coupling. NMR spectroscopic studies reveal the unsymmetric nature of the dyads. All of the dyads undergo two reversible reductions, which demonstrates their structural and electrochemical rigidity. The synthesised dyads show a remarkable redshift in their absorption...
In this review article, we have described various strategies to increase the efficiency of two-photon absorption process of porphyrin related molecular systems. While 18-π electronic aromatic porphyrin monomers exhibit relatively small two-photon absorption cross-section values, the perturbation of electronic nature of porphyrins by substituting electron donating–accepting moieties, π-conjugated peripheral...
