Herein, we report on the design, synthesis, and in-depth characterization of a new class of dual-emissive (visible and NIR) metal naphthalocyaninates. A 4-N,N-dimethylaminophen-4-yl-substituted naphthalocyaninato zinc(II) complex (Zn-NMe2Nc) and the derived water-soluble coordination compound (Zn-NMe3Nc) exhibit a near-infrared fluorescence from the lowest ligand-centered state, along with a unique push\u2013pull-supported luminescence in the visible region of the electromagnetic spectrum. An unprecedentedly broad structural (2D-NMR spectroscopy and mass spectrometry) as well as photophysical characterization (steady-state state and time-resolved photoluminescence spectroscopy) is presented. The unique dual emission was assigned to two independent sets of singlet states related to the intrinsic Q-band of the macrocycle and to the push\u2013pull substituents in the molecular periphery, respectively, as predicted by TD-DFT calculations. In general, the elusive chemical aspects of these macrocyclic compounds are addressed, involving both reaction conditions, thorough purification, and in-depth characterization. Besides the fundamental aspects that are investigated herein, the photoacoustic properties were exemplarily examined using phantom gels to assess their tomographic imaging capabilities. Finally, the robust luminescence in the visible range arising from the push\u2013pull character of the peripheral moieties demonstrated a notable independence from aggregation and was exemplarily implemented for optical imaging (FLIM) through time-resolved multiphoton micro(spectro)scopy.<\/jats:p>","DOI":"10.3390\/ijms25052605","type":"journal-article","created":{"date-parts":[[2024,2,23]],"date-time":"2024-02-23T06:07:39Z","timestamp":1708668459000},"page":"2605","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Dual Emissive Zn(II) Naphthalocyanines: Synthesis, Structural and Photophysical Characterization with Theory-Supported Insights towards Soluble Coordination Compounds with Visible and Near-Infrared Emission"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7661-3231","authenticated-orcid":false,"given":"Sidharth Thulaseedharan Nair","family":"Sailaja","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Anorganische und Analytische Chemie, Universit\u00e4t M\u00fcnster, Corrensstra\u00dfe 28\/30, 48149 M\u00fcnster, Germany"},{"name":"CeNTech, CiMIC, SoN, Universit\u00e4t M\u00fcnster, Heisenbergstra\u00dfe 11, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iv\u00e1n","family":"Maisuls","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische und Analytische Chemie, Universit\u00e4t M\u00fcnster, Corrensstra\u00dfe 28\/30, 48149 M\u00fcnster, Germany"},{"name":"CeNTech, CiMIC, SoN, Universit\u00e4t M\u00fcnster, Heisenbergstra\u00dfe 11, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1288-925X","authenticated-orcid":false,"given":"Alexander","family":"Hepp","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische und Analytische Chemie, Universit\u00e4t M\u00fcnster, Corrensstra\u00dfe 28\/30, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana","family":"Br\u00fcnink","sequence":"additional","affiliation":[{"name":"Institute for Solid State Theory and Center for Multiscale Theory and Computation, Universit\u00e4t M\u00fcnster, Wilhelm-Klemm-Stra\u00dfe 10, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0669-5854","authenticated-orcid":false,"given":"Nikos L.","family":"Doltsinis","sequence":"additional","affiliation":[{"name":"Institute for Solid State Theory and Center for Multiscale Theory and Computation, Universit\u00e4t M\u00fcnster, Wilhelm-Klemm-Stra\u00dfe 10, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Faust","sequence":"additional","affiliation":[{"name":"European Institute for Molecular Imaging, Universit\u00e4t M\u00fcnster, R\u00f6ntgenstra\u00dfe 16, 48149 M\u00fcnster, Germany"},{"name":"Department of Nuclear Medicine, University Hospital M\u00fcnster, Albert-Schweitzer-Campus 1, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Hermann","sequence":"additional","affiliation":[{"name":"European Institute for Molecular Imaging, Universit\u00e4t M\u00fcnster, R\u00f6ntgenstra\u00dfe 16, 48149 M\u00fcnster, Germany"},{"name":"Department of Nuclear Medicine, University Hospital M\u00fcnster, Albert-Schweitzer-Campus 1, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian A.","family":"Strassert","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische und Analytische Chemie, Universit\u00e4t M\u00fcnster, Corrensstra\u00dfe 28\/30, 48149 M\u00fcnster, Germany"},{"name":"CeNTech, CiMIC, SoN, Universit\u00e4t M\u00fcnster, Heisenbergstra\u00dfe 11, 48149 M\u00fcnster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1039\/D0MH01316A","article-title":"Dual Emission in Purely Organic Materials for Optoelectronic Applications","volume":"8","author":"Kukhta","year":"2021","journal-title":"Mater.
