series of dyes bearing polymethine chromophore units in borondipyrromethene (BODIPY) α-positions were prepared by condensation of 3,5-dimethyl borondipyrromethene with various hemicyanines. One or two methyl groups of the starting material can react, yielding the corresponding mono- and disubstituted derivatives. The deeply coloured monosubstituted dyes belong to the family of merocyanine dyes and exhibit

UV/Vis and NIR spectral regions following selective excitation of the BODIPY‐based antenna. Initial charge transfer from the ferrocene to the BODIPY core was shown to outcompete sub‐100 fs deactivation of the excited state mediated by the catechol bridge. However, no subsequent electrontransfer to the fullerene acceptor was observed. The initial charge separated state relaxes by recombination with a

as well as X-ray crystallography. The redox properties of new donor–acceptor BODIPY dyads and triads were studied by electrochemical (cyclic voltammetry (CV) and differential pulse voltammetry (DPV)) and spectroelectrochemical approaches. Formation of weakly bonded noncovalent complexes between the new pyrene–BODIPYs and nanocarbon materials (C60, C70, single-walled carbon nanotube (SWCNT), and graphene)

investigate the electronicstructure as well as explain the UV–vis and redoxproperties of organometallic compounds 2–4 and 6. TDDFT calculations allow for assignment of the charge-transfer and π → π* transitions in the target compounds. The excited state dynamics of the parent BODIPY 1 and dyads 2–4 and 6 were investigated using time-resolved transient spectroscopy. In all organometallic dyads 2–4 and

Meso-nitrile oxide group in 1,7-Diphenyl-containing BODIPYs undergoes an unusual [3+2] intramolecular cycloaddition reaction with the formation of the dihydrobenzo[d]isoxazole-containing BODIPYs. Oxidation of these compounds results in the formation of unprecedented either benzisoxazole- or benzo[b]azepine-fused fully conjugated NIR absorbing BODIPYs. The properties of the target compounds were studied
