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 30 carbon atoms in total); ethers, esters, thereof; acid addition salts thereof; wherein Ar is a C.sub.15-18 fused tetracarbocyclic ring system containing 3 or 4 aromatic rings or a C.sub.17-22 fused pentacarbocyclic ring system containing 4, or 5 aromatic rings, or a substituted derivative thereof; the ring system Ar should be planar or deviate only slightly from planarity. Thus, the ring system contains a maximum of two non-aromatic carbon atoms which may be in the same ring, in which case they are adjacent, or in different rings; Ar is not perylene, fluoranthene, chrysene, pyrene, or triphenylene; 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 carboxylic 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.
本发明涉及公式(I)ArCH.sub.2 R.sup.1(I)的化合物或其单甲基或单乙基醚(包括这些醚的公式(I)化合物总共不超过30个碳原子);它们的醚,酯;酸加成盐;其中Ar是一个C.sub.15-18融合四环芳烃环系统,包含3或4个芳香环或C.sub.17-22融合五环芳烃环系统,包含4或5个芳香环,或其取代衍生物;环系统Ar应该是平面的或者仅稍微偏离平面。因此,环系统包含最多两个非芳香碳原子,它们可以在同一个环中,此时它们是相邻的,或者在不同的环中;Ar不是苝、芴、蒽、芘或三苯基;R.sup.1含有不超过八个碳原子,是一个##STR1##基团,其中m为0或1;R.sup.5是氢;R.sup.6和R.sup.7相同或不同,每个都是氢或C.sub.1-5烷基,可选地被羟基取代;R.sup.8和R.sup.9相同或不同,每个都是氢或C.sub.1-3烷基;##STR2##是一个五元或六元饱和羧酸环;R.sup.10是氢、甲基或羟甲基;R.sup.11、R.sup.12和R.sup.13相同或不同,每个都是氢或甲基;R.sup.14是氢、甲基、羟基或羟甲基。
