TL;DR: The lowest electronic absorption bands become increasingly intensified and red-shifted upon the increase in the number of porphyrins and eventually reach a peak electronic excitation for the dodecamer at ∼3500 wavenumber.

TL;DR: In this Review, the recent progress of the chemistry of expanded porphyrins after the seminal Review by Sessler and Seidel in 2003 is presented.

TL;DR: This review aims to cover the multitude of synthetic methodologies that have been developed for the construction of conjugated porphyrin arrays as well as to summarise their structure-property relationships and use in various applications such as near infrared (NIR) dyes, nonlinear optical materials and electron-conducting molecular wires.

TL;DR: Recent research in the laboratories in the synthesis of covalently and noncovalently linked discrete cyclic porphyrin arrays as models of the photosynthetic light-harvesting antenna complexes aid in the understanding of the structural requirements for such very fast EET in natural light- Harvesting complexes.

TL;DR: A variety of directly linked porphyrin arrays including linear, windmill, gridlike, cyclic, and box architectures are developed, which exhibit an exceptionally low HOMO-LUMO gap as a result of a fully conjugated pi electronic system over a coplanar platform.
