An In‐Situ Cyanidation Strategy To Access Tetracyanodiacenaphthoanthracene Diimides with High Electron Mobilities Exceeding 10 cm² V⁻¹ s⁻¹

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(34)

Published: July 3, 2023

Abstract A family of novel highly π‐extended tetracyano‐substituted acene diimides, named as tetracyanodiacenaphthoanthracene diimides (TCDADIs), have been synthesized using a facile four‐fold Knoevenagel condensation strategy. Unlike conventional cyano substitution reactions, our approach enables access to large π‐conjugated backbone with the in‐situ formation four substitutents at room temperature while avoiding extra cyano‐functionalization reactions. TCDADIs decorated different N‐alkyl substituents present good solubility, near‐coplanar backbones, crystallinity, and low‐lying lowest unoccupied molecular orbital energies −4.33 eV, all which contribute desirable electron‐transport performance when applied in organic field‐effect transistors (OFET). The highest electron mobility an OFET based on 2‐hexyldecyl‐substituted TCDADI single crystal reaches 12.6 cm 2 V −1 s , is not only among values for reported n‐type semiconductor materials (OSMs) but also exceeds that most OSMs imide units.
