Efficient energy and electron transfer in photoexcited dye assemblies is central to biological and artificial light-harvesting systems. The highlighted work reports Förster-type transfer in multichromophore cassettes containing four BODIPY units linked to a pseudo-tetrahedral acceptor dye based on fused porphyrin and perylenediimide motifs.

Two complementary worlds of π aromaticity meet in one molecule. Di-p-benzihexaphyrin can switch between an antiaromatic Hückel topology and an edge-to-face Möbius conformer, with color changes revealing the effect of topology on π conjugation.

The two inner protons of 22-hydroxybenziporphyrin, a phenol-containing porphyrin analogue, act as a switch of antiaromaticity through keto-phenol tautomerization that interchanges [6]- and [20]annulenoid conjugation pathways.
