Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:89972-77-0) through the article.
Efficient aqueous-phase aldol condensation, Michael addition, and solvent-free Wittig reactions were successfully employed to synthesize two two-photon initiators 9-ethyl-3-[4-(2,2′:6′,2”-terpyridinyl-4′-yl)styryl]carbazole and 9-{4-[4-(2,2′:6′,2”-terpyridinyl-4′-yl)styryl]phenyl}carbazole. These two initiators with carbazolyl moiety attached to 2,2′:6′,2”-terpyridine present D-π-A-type framework, where A is a π-deficient terpyridine ring. The crystal structures were determined by single-crystal X-ray diffraction determination The exptl. results confirmed that the two initiators have sensitive single-photon-excited fluorescence (SPEF) and two-photon-excited fluorescence (TPEF) properties. The exptl. and theor. two-photon absorption (TPA) cross-sections were investigated. Two-photon initiation polymerization (TPIP) microfabrication experiments were carried out, and possible polymerization mechanisms are discussed based on the theor. evaluation.
When you point to this article, it is believed that you are also very interested in this compound(89972-77-0)Computed Properties of C22H17N3 and due to space limitations, I can only present the most important information.
