V-Shaped Hole-Transporting TPD Dimers Containing Troger's Base Core
JOURNAL OF PHYSICAL CHEMISTRY C 121:19 (2017) 10267-10274
Abstract:
V-shaped hole transporting materials based on N,N,N′,N′-tetraarylbenzidine (TPD)-type moieties conjoined by Tröger’s base core were synthesized and investigated. These hole transporting materials were obtained by a three-step synthetic method, are fully amorphous, and demonstrate high glass transition temperatures and good thermal and morphological stability. Relatively high charge mobility (up to 0.036 cm2 V –1 s–1) was measured in these hole transporting materials, exceeding that of corresponding methyl and methoxy substituted TPD analogues without TB core by more than 2 orders of magnitude. Determined ionization potential and charge mobility values permit use of the synthesized compounds as hole transporting materials in fabrication of perovskite solar cells.Solution-processed cesium hexabromopalladate(IV), Cs2PdBr6, for optoelectronic applications
