near-IR absorbing and emitting bacteriochlorin, and BODIPY derivatives with differentabsorptionbands in the visible region (503–668 nm) have been synthesized. Absorptionband of BODIPY was tuned by installation of 0, 1, or 2 styryl substituents [2-(2,4,6-trimethoxyphenyl)ethenyl], which leads to derivatives with absorptionmaxima at 503, 587, and 668 nm, respectively.

BDP unit to the Pt(II) coordination center occurred (6.7 ps), accompanied by an ultrafast intersystem crossing at the Pt(II) coordination center (<1 ps) and triplet–triplet energy transfer back to the BDP moiety (148 ps). These processes generated a triplet state localized at BDP, and the lifetime was 103.2 μs, much longer than the triplet-state lifetime of Pt-Ph (3.5 μs), a complex without the BDP moiety

The designed protocol enables a fine modulation of the photonic performance of BODIPY-based molecular assemblies. The choice of the spacer and building blocks leads to triads featuring tunable singlet oxygen generation and an energy transfer laser.

molecule was designed and synthesized based on a known central truxene platform. Two BODIPY derivatives and one corrole macrocycle were introduced and connected to the 2, 7 and 12-positions of the truxene unit by Suzuki coupling. The dyad was fully characterized by UV-vis absorption, protonnuclearmagneticresonance, mass spectrometry. The direction of energy transfer upon electronic excitation was
