A phosphazene derivative compound including a chain moiety including a backbone and an attached fluorine atom and an opto-electronic device including such compound. The chain moiety includes an intermediate moiety, a terminal moiety arranged at a terminal portion of thereof bonded to the intermediate moiety, and/or a core moiety comprising a phosphazene unit attached to the chain moiety, including by a linker moiety of the chain moiety. The chain moiety attaches to the phosphorous atom of the unit and/r comprises a cyclophosphazene comprising a plurality of units. The device has two electrodes and an active region comprising a semiconducting layer bounded longitudinally by the electrodes and laterally confined to an emissive region defined thereby that lacks the compound. A device patterning coating includes the compound in a first lateral portion. The device has a deposited layer of deposited material, but the first portion lacks a closed coating of deposited material.

The resin composition according to the present invention and a molded article of the composition contain a resin and a cyclic phosphazene compound represented by formula (1). A resin composition that has high flame retardancy while maintaining resin-derived mechanical strength, and a molded article of the composition are provided by using this configuration.
