已经合成了基于BODIPY和通过苯基间隔基连接的tellazine荧光团的新染料，荧光发射和电化学性质的特点BODIPY可以可逆地氧化成一个稳定的阳离子自由基，而四嗪可以还原成一个稳定的阴离子战术。电化学和吸收研究表明，这两个荧光团的行为独立。主要通过能量转移DFT计算和光谱电化学实验证明，当四嗪部分被电化学还原时，光诱导的电子转移和能量转移仍然是可能的，这阻止了BODIPY单元的荧光的开启
New dyes based on BODIPY and tell azine fluorophores connected through a phenyl spacer have been synthesized and their absorption, emission and electrochemical properties characterized BODIPY can be reversibly oxidized into a stable cation radical whereas tetrazine can be reduced to a stable anion tactical The electrochemical and absorption studies demonstrate that both fluorophores behave independently The bichromophoric compounds show an expected very weak emission by the BODIPY core that is quenched by the phenoxytetrazine mainly through energy transfer DFT calculations and spectroelectrochemistry experiments demonstrate that photoinduced election transfer and energy transfer remain possible when the tetrazine moiety is reduced electrochemically, which prevents switching on of the fluorescence of the BODIPY unit
