The highly fluorescent , unsymmetrically substituted boron–dipyrromethene dye 1 shows emission features that are strongly dependent on the solvent polarity. Thus, 1 can be used for highly sensitive fluorometric probing of solvent polarity and acidity and furthermore can be switched chemically or electrochemically in the near infrared.
