Pyrene-bodipy dyads: Optical properties and applications

Triplet–triplet sensitizing within pyrene-based COO-BODIPY: a breaking molecular platform for annihilating photon upconversion

“…This enables triplet excited state population by SOCT-ISC, mainly when such a moiety is linked at the BODIPY meso position. 18 In fact, theoretical simulations of the molecular orbitals (MOs) involved in MMAs 1–4 predict that the HOMO energy of the pyrene moiety can be energetically intercalated between the HOMO and LUMO gap of the BODIPY units. Thus, the PET probability is effectively modulated by the BODIPY substitution pattern (Fig.…”

Photophysicochemical and electrochemical properties of pyrene–BODIPY platforms

“…13 The structural relationships and their impact on optical properties between the BODIPY core substitution and the location of pyrene (at the meso, pyrrole moiety, and boron central atom) have been investigated in detail. 14 The maximum absorption wavelengths of BODIPYs are not considerably impacted by the substitution of BODIPYs at the meso position. [15][16][17] On the other hand, significant differences in the absorption and emission wavelengths result from altering the substitution pattern on the pyrrole moiety of the BODIPY core.…”
