General description

1,4-Diiodotetrafluorobenzene forms trimeric complexes as new, halogen-bonded mesogens with two molecules of alkoxystilbazole. The electron density study of the halogen-bonded complex of 4,4′-dipyridyl-N,N′-dioxide with 1,4-diiodotetrafluorobenzene at 90K has been reported.

1,4-Diiodotetrafluorobenzene is a ditopic perfluorinated iodobenzene used for cocrystallization of halopyridinium salts.

Application

1,4-Diiodotetrafluorobenzene has been used as the halogen bonding donor during the preparation of phosphorescent cocrystal with polycyclic aromatic hydrocarbons.

The halogen-bond (X-bond) donors 1,3- and 1,4-diiodotetrafluorobenzene (1,3-di-I-tFb and 1,4-di-I-tFb, respectively) form cocrystals with trans-1,2-bis(2-pyridyl)ethylene (2,2'-bpe) assembled by N···I X-bonds. In each cocrystal, 2(1,3-di-I-tFb)·2(2,2'-bpe) and (1,4-di-I-tFb)·(2,2'-bpe), the donor molecules support the C=C bonds of 2,2'-bpe to undergo an intermolecular [2+2]

Here we introduce a σ-hole-containing volatile solid additive, 1, 4-diiodotetrafluorobenzene (A3), in PM6:Y6-based OSCs. Aside from the appropriate volatility of A3 additive, the synergetic halogen interactions between A3 and photoactive matrix contribute to more condensed and ordered molecular arrangement in
