The blue emission of M2biQ can be tuned to specific wavelengths throughout the visible region by changing the identity of the cation it interacts with. These optical properties are observed in MeCN solution and the solid state. White light is obtained in MeCN by using either the proper ratio of zinc ions or acid. Thus, M2biQ acts as a nearly universal emitter (λem = 468-690 nm) with large Stokes shifts (116-306 nm, Δν̃ = 7,042-11,823 cm-1). Full spectral profiles as well as quantum yields, lifetimes, and the crystal structures of key RGB and yellow emitters are reported. Emission wavelengths correlate with cationic radius, and TD-DFT calculations show that, for 1:1 complexes, the smaller the ion, the shorter the N-cation bond, and the greater the bathochromic emission shift.

具有单一输入可调有机荧光团的全可见光谱和白光发射

通过改变与之相互作用的阳离子的身份，M2biQ 的蓝色发射可以调谐到整个可见光区域的特定波长。这些光学性质在 MeCN 溶液和固态中观察到。通过使用适当比例的锌离子或酸在 MeCN 中获得白光。因此，M2biQ 充当具有大斯托克斯位移（116-306 nm，Δν̃ = 7,042-11,823 cm-1）的几乎通用的发射器（λem = 468-690 nm）。报告了全光谱轮廓以及量子产率、寿命以及关键 RGB 和黄色发射器的晶体结构。发射波长与阳离子半径相关，TD-DFT 计算表明，对于 1:1 复合物，离子越小，N-阳离子键越短，红移发射位移越大。
