TPA-active D–π–D fluorophores with rigid, planar cores from phenylene to indenofluorene and indolocarbazole
摘要:
A series of D-pi-D quadrupolar fluorophores with systematically varied pi-conjugated cores were prepared using the Heck reaction and their single- and two-photon photophysical properties were examined. Introduction of extended pi-conjugated cores such as indenofluorene/indolocarbazole was found to induce only small shifts in the absorption and emission maxima versus the phenylene linked fluorophore but greatly enhance their single- and two-photon absorption cross-sections. The effects of positional substitution oil the properties of the indolocarbazole derivatives were also investigated. (C) 2009 Elsevier Ltd. All rights reserved.

The synthesis, characterization, and field-effect transistor (FET) properties of new indolo[3,2-b]carbazoles are described. In particular, an extensive characterization of their crystal structures has revealed the importance of the nature of the side chains (alkyl, phenyl, thienyl substituents) on their solid-state organization. These organic materials have exhibited p-type FET behavior with hole mobilities
描述了新型吲哚 [3,2-b] 咔唑的合成、表征和场效应晶体管 (FET) 特性。特别是,对其晶体结构的广泛表征揭示了侧链(烷基、苯基、噻吩基取代基)的性质对其固态组织的重要性。这些有机材料表现出 p 型 FET 行为,空穴迁移率高达 0.2 cm2 V(-1) s(-1),开/关电流比高于 10(6)。使用苯基取代的吲哚并[3,2-b]咔唑获得了最好的结果,因为苯基取代基的存在似乎允许低聚分子之间有效重叠。更重要的是,FET 特性在空气中的几个月内保持不变。
