New meso-CF₃-substituted BODIPY derivatives have been synthesized using the methodology that includes as a key step the condensation of pyrroles with trifluoro(2,3-cycloalkanopyrrol-2-yl)ethanols. The further reaction of dipyrromethanes thus obtained with DDQ followed by complexation with BF₃ leads to either benzo[b]-fused (in the case of dipyrromethanes obtained from trifluoro(4,5,6,7-tetrahydroindol-2-yl)ethanol) or cycloheptano[b]-fused saturated or partially saturated BODIPY dyes. The latter exhibit strong red fluorescence (λ_em = 588–634 nm, Φ_f = 0.54–0.68), while benzo[b]-fused do not fluoresce at all in either polar or non-polar solvents. The performed quantum-chemical calculations (TD-CAM-B3LYP/SVP) explain the spectroscopic results.

已经使用包括作为关键步骤的吡咯与三氟（2,3-环烷吡咯-2-基）乙醇缩合的方法合成了新的内消旋CF _3-取代的BODIPY衍生物。如此获得的二吡咯甲烷与DDQ进一步反应，然后与BF ₃络合导致苯并[b]稠合（在二吡咯甲烷由三氟（4,5,6,7-四氢吲哚-2-基）乙醇制得的情况下）或环庚烷[b]稠合的饱和或部分饱和的BODIPY染料。后者表现出强烈的红色荧光（λ _EM  = 588-634纳米，Φ _˚F = 0.54–0.68），而在极性或非极性溶剂中，苯并[b]融合均不发出荧光。进行的量子化学计算（TD-CAM-B3LYP / SVP）解释了光谱结果。
