Planar Heptathienoacenes Based on Unsymmetric Dithieno[3,2‑b:3′,4′-d]thiophene: Synthesis and Photophysical Properties

posted on 2016-08-18, 00:00 authored by Qiuxin Liu, Xiuxiu Gao, Hao Zhong, Jinsheng Song, Hua WangThe unsymmetric dithieno[3,2-b:3′,4′-d]thiophene
(ts-DTT) was efficiently
synthesized, and two novel heptathienoacenes
with linear and bull’s horn shapes were designed and prepared
via different ring cyclization connection manners. All intermediates
and aimed heptathienoacenes were fully characterized by 1H NMR, 13C NMR, and HRMS. Their UV–vis absorption
behavior, fluorescence, and electrochemical properties are characterized.
In addition, DFT quantum calculation was employed to further understand
the electron distribution and the origin of the absorption bands.
