Striking Increase in Hole Mobility upon Metal Coordination to Triphenylene Schiff Base Semiconducting Multicolumnar Mesophases Domingo de la Rubia, Estela de Folcia, César L. Ortega, Josu Etxebarria, Jesús Termine, Roberto Golemme, Attilio Coco Cea, Silverio Espinet Rubio, Pablo Producción Científica This paper reports the synthesis, liquid-crystal behavior, and charge-transport properties in the mesophase of triphenylene Schiff bases and their copper(II), nickel(II), and oxovanadium(IV) complexes. The thermal and electronic properties of the Schiff bases are modulated by coordination to the corresponding metal moieties, which have the ability to self-assemble into linear structures and help the alignment of the triphenylene columns. This produces two kinds of electronically nonconnected columnar regions, one purely organic and one more inorganic. The most remarkable effect is a striking charge mobility enhancement in the metal-containing mesophases, due to the contribution of the more inorganic columns: in comparison to values of hole mobility along the columnar stacking for the purely organic columnar mesophases, on the order of 10–7 cm2 V–1 s–1, these values jump to 1–10 cm2 V–1 s–1 in these hybrid inorganic/organic columnar materials. 2020-09-29T10:28:29Z 2020-09-29T10:28:29Z 2020 info:eu-repo/semantics/article Inorganic Chemistry, 2020, 59, 15, 10482–10491 0020-1669 http://uvadoc.uva.es/handle/10324/42651 10.1021/acs.inorgchem.0c00794 10482 15 10491 Inorganic Chemistry 59 1520-510X eng https://pubs.acs.org/doi/10.1021/acs.inorgchem.0c00794 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2019 American Chemical Society Attribution-NonCommercial-NoDerivatives 4.0 Internacional American Chemical Society SI
