Zusammenfassung:The large amount of unstable species in the realm of interstellar chemistry drives an urgent need to develop efficient methods for the in situ generations of molecules that enable their spectroscopic characterizations. Such laboratory experiments are fundamental to decode the molecular universe by matching the interstellar and terrestrial spectra. We propose an approach based on laser ablation of nonvolatile solid organic precursors. The generated chemical species are cooled in a supersonic expansion and probed by high‐resolution microwave spectroscopy. We present a proof of concept through a simultaneous formation of interstellar compounds and the first generation of aminocyanoacetylene using diaminomaleonitrile as a prototypical precursor. With this micro‐laboratory, we open the door to generation of unsuspected species using precursors not typically accessible to traditional techniques such as electric discharge and pyrolysis. Laser ablation of solid organic compounds with high melting points is proposed for the in situ generation of new chemical species. Diaminomaleonitrile is used as a prototypical precursor, generating numerous interstellar compounds and aminocyanoacetylene for the first time. This experimental method could open the doors towards the discoveries of unsuspected molecules in space.
