Abstract:
A novel and highly conjugated aromatic carboxylic acid,3,4,5-trisbenzyloxy benzoic acid (TBBA) and the corresponding Tb3+ complex has been synthesized and characterized by various spectroscopic techniques. The room temperature photoluminescence spectrum of Tb3+ complex is composed of typical green emissions, assigned to transitions between the first excited state 5D4 to the 7FJ (J = 6,5,4,3),with an excited state lifetime of 0.397 ms and a quantum yield of 1%.
