complexes are fundamentally not good for this purpose

发帖数: 432 | 4 I did some literature search and found Cr(II), upon excitation, can not
oxidize I- while Cr(III) complexes are not very stable.
If we can prepare stable Cr(III) complexes, can we use Cr(III) complexes as
dyes? I will say "probably yes"

I think as long as you can get much higher performance from Cr complex,
nobody will care if it is toxic or not.

发帖数: 2567 | 11 how do the energy levels of Cr2+/3+ align with those of TiO2 and I-/I3-?
not only for electron transfer, also for hole transfer.
they need to be favorable for both ends then also stable.

发帖数: 2 | 12 感觉上不可行。Cr(II)激发态未必能向氧化物半导体注入电子，有可能是能级不够，有
可能是激发态寿命不够，铁的配合物就是这样。就算能够注入，Cr(III)的电位太负，
非常接近TiO2的导带，只能够与注入的电子重组，白忙了。。。
