- Hole Transfer Processes in meta- and para-Conjugated Mixed Valence Compounds: Unforeseen Effects of Bridge Substituents and Solvent Dynamics
-
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
-
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.

- Synthesis and structure/property correlation of fully functionalized photorefractive polymers
-
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.
