| Özet |
| In this study, five homoconjugated NLOphore candidates decorated with indole donor groups were synthesized in 55–85% yields via click-type formal [2+2] cycloaddition reactions. The obtained compounds were subsequently transformed into spirocyclic push–pull-type chromophores through thermal rearrangements, affording the corresponding spiro products in 54–80% yields. During the formation of the spiro derivatives, the commonly reported low-yield issue associated with aniline-containing substrates in the literature was successfully overcome through the incorporation of indole donor groups, enabling the efficient formation of the target structures. All target compounds were investigated by UV/vis spectroscopy, thermogravimetric analysis (TGA), theoretical calculations, and custom-made Z-scan experiments. The homoconjugated structures exhibit intramolecular charge-transfer (ICT) absorption bands … |
