Tetraphenylporphyrin and dipole moments

A copper(II) ion fits perfectly into the center of tetraphenylporphyrin (TPP), and i was wondering if by doing so, will it become more polar or less polar than the original TPP?

this is something that i forgot, but can someone please correct me if i am wrong?

if a molecule has no dipole moment, then it is non polar right? and the more dipole moment it has, the more polar it is right?

also..tetraphenylchlorine has a dipole moment, while tetraphenyloporphin has no dipole moment right?

Hello,

A copper ion is present in the center of TPP molecule... It has ionic and coordinatively covalent bonds between Cu and TPP nitrogens. So I presume that the resulting non-ionic molecule would be more polar than original TPP, as there should be an electron flow through Cu center.
