“…[36] Die kooperative Bildung von supramolekularen Leiterstrukturen wurde in Denaturierungsexperimenten gemessen, [30] und Bindungskurven für die Verdrängung von multivalenten Liganden aus cyclischen Porphyrinoligomeren durch Pyridin sind mit den simulierten Kurven in Abbildung 16 im Einklang. [37] 3. Überlegungen zum Standardzustand Die Beziehung zwischen allosterischer und chelatbedingter Kooperativität lässt sich anhand der freien Energie veranschaulichen; wir vergleichen hierzu die freie Bildungsenergie der Komplexe AA·B 2 und c-AA·BB (Abbildungen 4 a und 9).…”

“…The emission maxima for 6 c-f are not significantly different whereas the smaller cycles 6 a and 6 b show a much weaker fluorescence band that is shifted to longer wavelengths, as a result of the high ring strain. [12] The distorted conformation of the smallest cycle 6 a is also the origin of the much narrower absorption band and the emergence of a new lower energy transition (S 0 !S 1 ), which can be directly correlated with theoretical predictions.…”
