“…Quantum yields 5 were determined from corrected emission spectra following the standard methods using 5,10,15,20-tetraphenylporphyrin zinc (Φ = 0.03 in toluene) as standards. 68,69 The time-resolved fluorescence decays were recorded with the time-correlated single photon counting (TCSPC) method. Data analysis was conducted 10 via commercial software (DAS6 fluorescence decay analysis software) provided by Horiba Instruments.…”

Three meso-2'-linked porphyrin-BODIPY hybrids which contain one, two, and four BODIPY units (, , and ), respectively, were synthesized. Their photophysical properties were investigated by UV-vis and fluorescence spectroscopy, cyclic voltammetry, and femtosecond transient absorption spectroscopy, as well as by theoretical calculations. The electronic properties of the constituent chromophores were found to be largely retained in these hybrids. Meanwhile, efficient and rapid energy transfers from (1)* to were evaluated to be 1.2 × 10(11), 1.5 × 10(11), and 1.1 × 10(11) s(-1), respectively.

View full text Add to dashboard Cite

Multicomponent molecular assemblies of 15 crown 5 containing 4 styrylpyridine with phthalic acid in the presence of potassium perchlorate were studied. The structure of the obtained complicated assemblies was determined by 1 H and 13 C NMR spectroscopy, UV spec troscopy, and X ray analysis. The composition of the supramolecular complexes was estab lished by spectrophotometric titration, and the stability constants were calculated. The quan tum yields of fluorescence for the ligand and its complexes of various nature were determined.
