No, there are no chiral centres.

Every asymmetric carbon (also known as chiral carbon) atom has for different groups attached to it. Those molecules have no planes of symmetry or axes of symmetry with respect to chiral carbon atoms.

achiral isusually contain aplane of symmetry

Anthracene is not chiral, if you draw a mirror image of the molecule you find that it is superimposable. All chiral compounds must have an enantiomer which is an identical compound that is nonsuperimposable.

And maleic anhydride is superimposable as well so therefore it isn't chiral. (If I assume you're referring to a Diels-Alder reaction then you'd probably like to know the answer to this as well.)
