ct.category theory - Derived Functors in arbitrary triangulated categories

Let mathcalD be a triangulated category, mathcalC a triangulated subcategory and Q:mathcalDtomathcalD/mathcalC the corresponding Verdier-localization. Now suppose we have a triangulated functor mathbbF:mathcalDtomathcalT to some other triangulated category mathcalT.



My question is the following: Under which circumstances do we have some kind of "right derived" functor of mathbbF with respect to mathcalC? By that I mean a triangulated functor textbfRmathbbF:mathcalD/mathcalCtomathcalT together with a natural transformation mathbbFRightarrowtextbfRmathbbFcircQ which is initial with this property.



Does there exist such a treatment of derived functors in arbitrary triangulated categories?



Thank you.
