| 2 | Two Dimensional Triptycene End-Capping and Its Influence on the Self-Assembly of Quinoxalinophenanthrophenazines显示文摘In this report we investigated two-dimensionally triptycene end-capped QPPs in terms of their solution and solid-state behavior.For this purpose,a triphenylene based ortho-diamine decorated with two triptycenyl units as well as a phenylene diamine with two non-annulated triptycene units have been synthesized.Sequences of condensation reactions with a pyrene-based tetraketone and ortho-diamines yielded a series of QPPs and UV/Vis investigations of the corresponding compounds led to the conclusion,that the QPPs form dimers in solution,which was further supported by MALDI-TIMS-TOF-MS.Single-crystal X-ray analysis of the triply and quadruply triptycene end-capped QPPs furthermore showed shortπ-π-distances of 3.3-3.4?and a perfect shape match during the dimerization of the triply triptycenyl end-capped QPP making it possible synthon for crystal engineering. | Lisa Ro■ Julius Reitemeier Farhad Ghalami Wen-Shan Zhang Jurgen H.Gross Frank Rominger Sven M.Elbert Rasmus Schroder Marcus Elstner Michael Mastalerz | 2023 | Chinese Journal of Chemistry2023，41，10： | 0 |
