The present invention relates to compounds of formula (I) ArCH.sub.2 R.sup.1 (I) or a monomethyl or monoethyl ether thereof (the compound of formula (I) including these ethers may contain no more than 29 carbon atoms in total); ethers, esters thereof; acid addition salts thereof; wherein Ar is a fused tricyclic aromatic ring system containing a maximum of 14 ring atoms and at least one heteroatom or a fused pentacyclic ring system with at least 4 aromatic rings containing a maximum of 22 ring atoms and at least one heteroatom; or a substituted derivative thereof; for either the tricyclic or pentacyclic ring system there is a maximum of one heteroatom for each ring present but preferably only one or two of the rings contain a heteroatom; the rings forming the tricyclic or the pentacyclic ring system contain five or six atoms; the heteroatoms are conveniently nitrogen, phosphorus, oxygen, sulfur or selenium; suitably the heteroatom is oxygen, sulfur or nitrogen; the tricyclic or the pentacyclic ring system should be planar or deviate only slightly from planarity; suitably the ring system is aromatic or contains one non-aromatic ring; preferably the ring system is aromatic; nitrogen atoms contained in five-membered rings are substituted by hydrogen, methyl or ethyl; R.sup.1 contains not more than eight carbon atoms and is a group ##STR1## wherein m is 0 or 1; R.sup.5 is hydrogen; R.sup.6 and R.sup.7 are the same or different and each is hydrogen or C.sub.1-5 alkyl optionally substituted by hydroxy; R.sup.8 and R.sup.9 are the same or different and each is hydrogen or C.sub.1-3 alkyl; ##STR2## is a five or six-membered saturated carbocyclic ring; R.sup.10 is hydrogen, methyl or hydroxymethyl; R.sup.11, R.sup.12 and R.sup.13 are the same or different and each is hydrogen or methyl; R.sup.14 is hydrogen, methyl, hydroxy, or hydroxymethyl.
