The studied compounds consist of p-quinodimethane moieties, which suffer from geometric perturbation with bond angles of around 90°. The substituent effects on structural parameters, local aromaticity, and properties were systematically explored. © 2021 American Chemical Society.article; structure activity relation; synthesisDiindeno[2,1- b:2′,1′- h]biphenylenes: Syntheses, Structural Analyses, and Propertiesjournal article10.1021/acs.orglett.1c03295347140802-s2.0-85118946476
