amine‐embedded flexible alkyl strap has been incorporated into an emissive boryl‐substituted dithienylpyrrole skeleton as a new entity of excited‐state intramolecularprotontransfer (ESIPT) chromophores. The π‐electron system shows a dual emission, which covers a wide range of the visible region depending on the solvent polarity. The incorporation of the aminoalkyl strap as well as the terminal boryl
