In this study, we report a donor\u2013acceptor\u2010engineered 2D conjugated coordination polymer (c\u2010CP), Ni\u2010TABQ (TABQ = tetraaminobenzoquinone), as a narrow\u2010bandgap semiconductor. The TABQ ligands integrate electron\u2010rich amino donors and electron\u2010deficient quinone carbonyl acceptors within the same molecular backbone, endowing the Ni\u2010TABQ lattice with strong intramolecular charge\u2010transfer absorption and a built\u2010in driving force for charge separation. Benefiting from strong broadband absorption and high charge\u2010carrier mobility, the vapor\u2010phase\u2010grown Ni\u2010TABQ thin films enable photodetection from 350 to 1400\u00a0nm under a 3\u00a0V bias, with a measurable response tail above 1150\u00a0nm, further achieving a responsivity of up to 3.1 A W\n                    <jats:sup>\u22121<\/jats:sup>\n                    , a specific detectivity of up to 6.58 \u00d7 10\n                    <jats:sup>10<\/jats:sup>\n                    Jones (625\u00a0nm at \u223c85 \u00b5W cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    ), and a response time of \u223c206 \u00b5s, while maintaining stable operation at 3\u00a0V over 8500\u00a0s of continuous cycling. These metrics compare favorably with state\u2010of\u2010the\u2010art broadband photodetectors based on standalone 2D materials, establishing donor\u2013acceptor molecular engineering within the 2D metal\u2010organic lattice as an effective strategy for advancing high\u2010performance 2D optoelectronic devices.\n                  <\/jats:p>","DOI":"10.1002\/adma.75350","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T10:45:06Z","timestamp":1791542706000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Highly Sensitive Broadband Photodetectors Based on Donor\u2013Acceptor 2D Conjugated Coordination Polymers"],"prefix":"10.1002","author":[{"given":"Yunxu","family":"Chen","sequence":"first","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3939-6853","authenticated-orcid":false,"given":"Jinxin","family":"Liu","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  Halle (Saale) Germany"},{"name":"Center for Advancing Electronics Dresden (CFAED) &amp; Faculty of Chemistry and Food Chemistry TUD Dresden University of Technology  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Fu","sequence":"additional","affiliation":[{"name":"Center for Advancing Electronics Dresden (CFAED) &amp; Faculty of Chemistry and Food Chemistry TUD Dresden University of Technology  Dresden Germany"},{"name":"Max Planck Institute for Polymer Research  Mainz Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0799-9470","authenticated-orcid":false,"given":"Apurba","family":"Mahapatra","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Solid State and Materials Research  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4410-8239","authenticated-orcid":false,"given":"Dongxu","family":"Wang","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8487-0972","authenticated-orcid":false,"given":"Mike","family":"Hambsch","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Computer Engineering and Center for Advancing Electronics Dresden (CFAED) TUD Dresden University of Technology  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelika","family":"Wrzesi\u0144ska\u2010Lashkova","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Solid State and Materials Research  Dresden Germany"},{"name":"Chair for Emerging Electronic Technologies TUD Dresden University of Technology  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7068-440X","authenticated-orcid":false,"given":"Fabian","family":"Paulus","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Solid State and Materials Research  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0783-0707","authenticated-orcid":false,"given":"Yana","family":"Vaynzof","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Solid State and Materials Research  Dresden Germany"},{"name":"Chair for Emerging Electronic Technologies TUD Dresden University of Technology  Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0268-519X","authenticated-orcid":false,"given":"Stefan C.
