Thus, green emitters with full widths at half maximum (FWHMs) of &lt;20\u00a0nm are rarely reported, despite being highly desired. Herein, by properly fusing indolo(3,2,1\u2010\n                    <jats:italic>jk<\/jats:italic>\n                    )carbazole (ICZ) and naphthalene moieties, green MR emitters are reported, which have FWHMs of merely 13\u00a0nm (0.064\u00a0eV) and 14\u00a0nm (0.069\u00a0eV) in dichloromethane, accompanied by high photoluminescence quantum yields of &gt;95%, which represent not only the smallest FWHMs among all green MR emitters but also the first green emitters based on ICZ MR derivatives. Theoretical studies reveal that the orbital interactions between the antisymmetric sites of the segments play an important role in extending the conjugation length in the fusion architectures while simultaneously maintaining a small FWHM. The corresponding organic light\u2010emitting diodes exhibit green emission peaks at 508\u2013509\u00a0nm and the first green electroluminescence FWHM of &lt;20\u00a0nm ever reported. Benefiting from the preferential horizontal dipole orientation, a high maximum external quantum efficiency of up to 30.9% is obtained, which remains at 28.9% and 23.2% under luminances of 1000 and 10\u00a0000 cd\u00a0m\n                    <jats:sup>\u22122<\/jats:sup>\n                    , respectively, outperforming most reported green devices based on narrowband emitters.\n                  <\/jats:p>","DOI":"10.1002\/adma.202211316","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T23:00:18Z","timestamp":1677711618000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":96,"title":["Orbital Symmetry Engineering in Fused Polycyclic Heteroaromatics toward Extremely Narrowband Green Emissions with an FWHM of 13\u00a0nm"],"prefix":"10.1002","volume":"35","author":[{"given":"Xuan","family":"Zeng","sequence":"first","affiliation":[{"name":"Key Laboratory of Organic Optoelectronics and Molecular Engineering of Ministry of Education Department of Chemistry Tsinghua University  Beijing 100084 P.
