TL;DR: A new type of donor-acceptor dyad, carbazolylaryl-substituted ortho-carboranes, which are conveniently prepared from the corresponding acetylenes and decaborane pathways, showed unique excited-state behavior associated with electron transfer unlike the meta- and para-counterparts.

TL;DR: The fluorescence spectra of smaller CPPs showed red-shifted fluorescence peaks, smaller fluorescence quantum yields, and longer lifetimes, when compared to those of larger ones, as investigated in this study.

TL;DR: In this paper, the effects of α- and β-cyclodextrins (CDs) on the twisted intramolecular charge transfer (TICT) emission of p-(N,N-diethylamino)benzoic acid (DEABA) in aqueous solution have been investigated by using steady-state and time-resolved fluorescence techniques.

TL;DR: Overall, the enhanced excited-state lifetimes for various hexaphyrins go in line with the increased TPA cross-section values and the ring planarity.

TL;DR: This Account discusses the work in harnessing SET pathways for photochemical synthesis, focusing on the successful production of macrocyclic polyethers, polythio ethers, and polyamides, and the discovery of efficient photochemical processes in which excited-state SET is followed by regioselective formation of carbon-centered radicals.
