In this contribution, a bindolylmaleimide dye (ABM) with anthracene substituted through a covalent single bond was synthesized and characterized by NMR and mass spectroscopic techniques. Emission of ABM was investigated in various solvents. The emission intensity of ABM is weak in dioxane and toluene, and negligible in other solvents. Frontier molecular orbitals calculation for ABM was carried out based on Dmol(3) package suit. Intramolecular charger transfer and free rotation of anthracene contributed to the non-radiative relaxation.
