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.
本发明涉及式(I)的化合物ArCH₂R¹(I)或其单甲基或单乙基醚(式(I)的化合物包括这些醚,总共含有不超过30个碳原子);醚、酯、其酸加成盐;其中Ar是含有3或4个芳香环的C₁₅-₁₈稠合四碳环系统或含有4或5个芳香环的C₁₇-₂₂稠合五碳环系统,或其取代衍生物;环系统Ar应为平面或仅略偏离平面。因此,环系统最多包含两个非芳香碳原子,它们可以在同一环中,在这种情况下它们是相邻的,或者在不同的环中;Ar不是芘、荧蒽、晕苯、芘或三亚苯;R¹包含不超过八个碳原子,并且是基团##STR1##其中m为0或1;R⁵是氢;R⁶和R⁷相同或不同,每个是氢或C₁-₅烷基,可选择性地被羟基取代;R⁸和R⁹相同或不同,每个是氢或C₁-₃烷基;##STR2##是一个五元或六元饱和羧酸环;R¹⁰是氢、甲基或羟甲基;R¹¹、R¹²和R¹³相同或不同,每个是氢或甲基;R¹⁴是氢、甲基、羟基或羟甲基。
