“…Two novel larger azaacenes with six or ten N atoms in their backbones, benzannelated 9,11,13,22,24,26-hexazatetrabenzo[a,c,l,n]heptacene (HATBH, 1) and benzannelated 9,26-dihydro-9,11,13,22,24,26-hexaza-tetrapyrido[3,2-a: 2′,3′-c: 3′′,2′′-l: 2′′′,3′′′-n]heptacene (DHATPH, 2), have been successfully synthesized in two steps. The theoretical band gaps estimated through DFT calculations for HATBH (1) and DHATPH (2) are 1.949 eV and 2.278 eV, which are close to the experimentally obtained optical band gaps (2.14 eV and 2.39 eV). …”

Pathways of energy transfer in LHCII revealed by room-temperature 2D electronic spectroscopy by Wells, Kym L., Lambrev, Petar H., Zhang, Zhengyang, Garab, Gyözö, Tan, Howe-Siang

“…Two-dimensional electronic spectroscopy has been used to study energy transfer dynamics in LHCII trimers from the chlorophyll b Qy band to the chlorophyll a Qy band. Observing cross-peak regions corresponding to couplings between different excitonic states reveals partially resolved fine structure at the exciton level that cannot be isolated by pump–probe or linear spectroscopy measurements alone. …”
