A Tetrathiafulvalene (TTF)‐Conjugated Microporous Polymer Network

Conjugated microporous polymer networks have been prepared from the strong electron donor tetrathiafulvalene (TTF) and 1,3,5-triethynylbenzene (TEB) by using the Sonogashira–Hagihara cross-coupling reaction. Optimization of reaction conditions yields polymers with surface areas of up to 434 m2 g−1. The strong electron-donating properties of the network can be proven by iodine exposure. Structural and electronic changes due to formation of the charge-transfer salt from TTFs in the porous network and iodine within the pores are investigated.
