Cover Feature: Tuning the Electronic Properties and Acid‐Response Behavior of N‐Heteroacene‐Based π‐Conjugated Liquids by Changing the Number of π‐Conjugated Substituents (Chem. Asian J. 18/2018)

Abstract

Two room‐temperature fluorescent π‐conjugated liquids based on a N‐heteroacene framework were designed and prepared with one or two thiophene rings. These liquid materials can be utilized as inks to be coated on substrates and displayed different electronic properties and rheology behavior; for example, fluorescent colors were light blue and blue, respectively. Moreover, dissolving various acids substances in these liquids gave rise to different fluorescent colors. Furthermore, when acids with lower pKa values were dissloved in these liquids, a phase transition occurred to a self‐organized liquid‐crystalline phase.
