  Dithieno[3,2-c:2′,3′-e]-2,7-diketophosphepin: A Unique Building Block for Multifunctional π-Conjugated Materials

  摘要：

  A series of conjugated materials based on the new dithieno[3,2-c:2',3'-e]-2,7-diketophosphepin (DTDKP) building block have been studied for the first time. Theoretical calculations predict DTDKP to be a better electron acceptor than the well-known dithienophosphole and the nitrogen analogue, bithiopheneimide. Cyclic voltammetry studies revealed two reduction processes that support their promising electron-acceptor properties, and modification of the P center with O or gold(I) further reduced the LUMO energy to ca. -3.6 eV. Expansion of the DTDKP core with various aromatic moieties has been realized using the Huisgen alkynyl click reaction, resulting in altered optical and electrochemical properties with compounds showing a high-energy absorption band at ca. 270-290 nm and a low-energy band at ca. 390-460 nm. The acceptor character of the DTDKP core was demonstrated by a red shift following the electron-donating strength of the appended aromatic moiety. Intriguing white-light emission from just a single species with the CIE coordinates of (0.33, 0.34) was observed for some of the extended species as the result of an unexpected dual-emission behavior. The high-energy emission in the blue-to-green region and the low-energy emission in the orange-to-red region are attributed to a pi* -> pi transition of the DTDKP core and charge transfer from the triazole moiety to DTDKP, respectively. Apart from tuning of the molecular properties, this novel building block has also been applied in a self-assembled organogel, which exhibited pronounced luminescence. Scanning electron microscopy confirmed that the gel self-assembled by forming a network of entangled ID fibrous structures on the micrometer scale.

  Methylation of the triazole units of a π-extended, fluorescent dithieno[3,2-c:2′,3′-e]-2,7-diketophosphepin gives rise to a N,N-dimethylated species that shows considerably blue-shifted absorption and emission wavelengths, as well as two reversible and remarkably low reduction steps at Ered = −1.12 and −1.39 V that underline its improved electron-acceptor features. The observed properties are the result
