Hayduk, Matthias,Riebe, Steffen,Rudolph, Kevin,Schwarze, Sandrina,van der Vight, Felix,Daniliuc, Constantin G.,Jansen, Georg,Voskuhl, Jens
, p. 927 - 931 (2018)
In this communication we report the synthesis and characterisation of a novel dianionic compound with aggregation-induced emission properties. This compound was able to recognize spermine via a multivalent electrostatic interaction leading to a restrictio
Synthesis of 5,12-Diazapentacenes and Their Properties
Garcia, Rosalva C.,Pech, Matthew J.,Sommer, Roger,Gorman, Christopher B.
, p. 15079 - 15086 (2019/11/21)
An efficient synthesis via a precursor route to a new class of linear dialkyldiaminoazapentacenes is reported. The synthetic route involves the coupling of 4-substituted aniline derivatives to 2,5-dibromoterephthalonitrile via Buchwald-Hartwig amination f

A compound represented by the general formula (11) is useful as a light-emitting material. R1, R2, R4 and R5 represent a group represented by the general formula (2), R11 to R20 represent a hydrogen atom or a substituent, and L12 represents a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group.
Hole Transfer Processes in meta- and para-Conjugated Mixed Valence Compounds: Unforeseen Effects of Bridge Substituents and Solvent Dynamics
Sch?fer, Julian,Holzapfel, Marco,Mladenova, Boryana,Kattnig, Daniel,Krummenacher, Ivo,Braunschweig, Holger,Grampp, Günter,Lambert, Christoph
, p. 6200 - 6209 (2017/05/09)
To address the question whether donor substituents can be utilized to accelerate the hole transfer (HT) between redox sites attached in para- or in meta-positions to a central benzene bridge, we investigated three series of mixed valence compounds based o
A Versatile One-Pot Access to Cyanoarenes from ortho- and para-Quinones: Paving the Way for Cyanated Functional Materials
Gl?cklhofer, Florian,Lunzer, Markus,St?ger, Berthold,Fr?hlich, Johannes
supporting information, p. 5173 - 5180 (2016/04/09)
A generally applicable direct synthesis of cyanoarenes from quinones is presented. Particular emphasis is placed on the preparation of precursors and target molecules relevant for organic materials, including halogenated cyanoarenes and larger cyanated acenes. The reaction and work-up protocols are adjusted for the challenges presented by the different substrates and products. Screening results of the initial reaction optimization are given to further facilitate adaptation to other synthetic problems. The universality of the reaction is finally highlighted by successful substitution of para-quinones by an ortho-quinone as the starting material.

An organic light-emitting device having a light-emitting layer containing a compound represented by the general formula below has a high light emission efficiency. In the general formula, at least one of R1 to R5 represents a cyano group, at least one of R1 to R5 represents a 9-carbazolyl group, a 1,2,3,4-tetrahydro-9-carbazolyl group, a 1-indolyl group or a diarylamino group, and the balance of R1 to R5 represents a hydrogen atom or a substituent.
Fluorene as the π-spacer for new two-photon absorption chromophores
Cheng, Jian-Zhang,Lin, Chao-Chen,Chou, Pi-Tai,Chaskar, Atul,Wong, Ken-Tsung
experimental part, p. 734 - 739 (2011/03/19)
We report herein the design and synthesis of two new quadrupolar D-π-A-π-D chromophores containing diphenyl amine and dicyanobenzene or 2,1,3-benzothiadiazole as electron donor (D) and acceptor (A), respectively, which are bridged by fluorene linkage (π).
Synthesis and structure/property correlation of fully functionalized photorefractive polymers
You, Wei,Wang, Liming,Wang, Qing,Yu, Luping
, p. 4636 - 4645 (2007/10/03)
This paper describes the synthesis and physical study of several new photorefractive polymers. The Heck reaction was successfully applied in the synthesis of these multifunctional polymers. These polymers are conjugated poly(phenylenevinylene)s copolymerized with a small amount of macrocyclic zinc complexes as the photosensitizers. Nonlinear optical chromophores were incorporated as the pendant groups. Both electron-rich and electron-deficient PPV backbones were synthesized. Experimental results showed that when an electron-rich photosensitizer is used, the electron-deficient component for charge transport (CN-PPV) enhances photorefractive performance and reduces the response time.
