meta-Terphenyl linked donor–π–acceptor dyads: intramolecular charge transfer controlled by electron acceptor group tuning

Abstract: Dyads were prepared to understand the electronic effects of a meta-terphenyl linker according to the accepting ability change. The charge transfer properties in the ground/excited state are determined by accepting ability and/or steric hindrance.

“…Regarding PY2 and PY3, LUMOs are localized partly on the pyrazolo[1,5-a]pyrimidine acceptor moiety and largely on the phenyl π-spacer. In contrast, the PY1 LUMO is localized only in the acceptor core, suggesting a stronger acceptor character of pyrazolo[1,5-a]pyrimidine with a substitution in position 3 compared to the other substitutions [69]. In addition, the theoretical calculated HOMO/LUMO values of As illustrated in Figure 4, the frontier molecular orbitals indicate that the PY1, PY2 and PY3 HOMOs are primarily localized on the 3,6-CzDMPA donor group.…”

“…Regarding PY2 and PY3, LUMOs are localized partly on the pyrazolo[1,5-a]pyrimidine acceptor moiety and largely on the phenyl π-spacer. In con-trast, the PY1 LUMO is localized only in the acceptor core, suggesting a stronger acceptor character of pyrazolo[1,5-a]pyrimidine with a substitution in position 3 compared to the other substitutions [69]. In addition, the theoretical calculated HOMO/LUMO values of PY1, PY2 and PY3 are −4.19/−2.02, −4.30/−1.93 and −4.35/−1.92, respectively, and the energy gap consequently increases in the order of PY1 (2.17 eV) < PY2 (2.37 eV) < PY3 (2.43 eV), following the same trend as the UV-visible characterizations (E gap opt = 2.25, 2.33 and 2.40 eV for PY1, PY2 and PY3, respectively).…”

“…The meta-terphenyl structure has only two phenyl units conjugated due to the electronic nodal site at the meta-position. [13] Considering these facts and the results obtained for Pt-O and Pt-P, it suggests that the degree of 𝜋-conjugation of the D-𝜋-A ligand increases in the order of Pt-O < Pt-M < Pt-P. Furthermore, as shown in Figure 1c,f, the torsion angles between the phenyl linker and Pt-C phenyl in donorfree Pt-PhIMI are 40.3°and 42.5°, which are larger than that of the Pt-P and smaller than that of the Pt-O.…”
