TL;DR: Detailed analyses of the solid-state Möbius structures of compounds 2b, 2c, and 2f showed that singly twisted structures are achieved without serious strain and that cyclic pi-conjugation is well-preserved, as needed for exhibiting strong diatropic ring currents.

TL;DR: This review highlights various porphyrinoid sensitizers reported till date and their photosensitizing ability both in vitro and in vivo studies and the urgent need for developing ideal photosensitizer for PDT is highlighted.

TL;DR: The third-order nonlinear optical response through measurement of two-photon absorption cross-sections (TPACS) for aromatic core-modified expanded porphyrin analogues by a femtosecond open aperture Z-scan method is reported.

TL;DR: Through the spectroscopic investigations, it is demonstrated that a subtle balance between the strains induced by the size of the [28]hexaphyrin macrocyclic ring and the energy stabilization contributed by pi-electron delocalization in the formation of distorted Möbius [28], leading to the molecular structure change into the MöBius topology as the temperature decreases.

TL;DR: The single-crystal X-ray structure of oxasmaragdyrin-ferrocene conjugate 9 reveals the planarity of the 22 pi skeleton with very small deviations of the meso-carbon atoms.
