2-Bromo-6-fluoronaphthalene (CAS number 324-41-4) is a fluorinated naphthalene derivative that is used either as interface material or as an intermediate for the construction of semiconducting molecules in application of OFETs, OLEDs and organic photovoltaics, perovskite solar cells.

2-Bromo-6-fluoronaphthalene can act as an interfacial modulator for full‐printable, mesoscopic perovskite solar cells (PMPSCs) through post-treatment. The bromo-terminal acts as an electrophilic site to interact with the iodine ion in perovskite via the noncovalent halogen bond. Meanwhile, the fused ring of naphthalene is capable to accommodate electron density that is attracted from the perovskite. This interaction induces a more favourable band structure at the interface [1].

Besides a decrease in HOMO and LUMO levels, fluorination may lead to an increase in intermolecular interaction via hydrogen bonding and/or π–π interactions thus to improve charge transport and device performance.
