(H4TTFTB) is used to synthesize Zn2(TTFTB),
a new metal–organic
framework that contains columnar stacks of tetrathiafulvalene and
benzoate-lined infinite one-dimensional channels. The new MOF remains
porous upon desolvation
and exhibits charge mobility commensurate with some of the best organic
semiconductors, confirmed by flash-photolysis-time-resolved microwave
conductivity measurements. Zn2(TTFTB) represents the first
example of a permanently porous MOF with high charge mobility and
may inspire further exploration of the electronic properties of these
materials.
