Pentacyclic derivatives having the general formulae (Ia), (Ib) and (Ic) ##STR1## denote: hydrogen, alkyl with 1 to 20 carbon atoms polyoxyhydrocarbyl, phenyl, phenylalkyl with 1 to 3 carbon atoms in the alkyl chain, wherein the alkyl residues or/and phenyl residues can be substituted by one or several hydroxy, halogen, sulfo, carboxy or alkoxycarbonyl groups in which alkoxy can have 1 to 4 carbon atoms; R.sup.7 denotes an alkyl group with 1 to 7 carbon atoms, substituted by at least one halogen, or denotes a carboxyalkyl group or a phenyl group which is substituted by a carboxy or alkoxycarbonyl group located at the o-position relative to the carbon atom bound to the pentacyclic ring system and by at least one halogen, wherein alkoxy can have 1 to 4 carbon atoms, or a carboxymethylene-oxy-alkyloxy group; the residues R.sup.14 and R.sup.15 as well as the positions on the rings in the formulae that are not marked by specific symbols denote any desired substituents which may optionally be linked together; the two bonds marked by a broken line mean that the two carbon atoms which are joined by the bond marked by a broken line can be linked together by a single or double bond; and X.sup.- is a counterion; as well as their derivatives activated at least at one of the residues R.sup.1, R.sup.7 or/and R.sup.13. The compounds can be used as absorption or fluorescent dyes, in particular as markers for hapten/antibody/protein conjugates, as laser dyes and as an absorption medium for solar collectors.
具有通式(Ia)、(Ib)和(Ic)的五环衍生物##STR1##表示:氢、具有1至20个碳原子的烷基、聚氧烃基、苯基、具有1至3个碳原子的烷基链上的苯基烷基,其中烷基残基和/或苯基残基可以被一个或几个羟基、卤素、磺酰基、羧基或烷氧羰基基团取代,其中烷氧基可以有1至4个碳原子;R.sup.7表示具有1至7个碳原子的烷基,至少被一个卤素取代,或表示一个羧基烷基或一个苯基,该苯基被一个羧基或烷氧羰基基团取代,该基团位于与五环环系统中的碳原子相对的o-位置,并且至少被一个卤素取代,其中烷氧基可以有1至4个碳原子,或者是一个羧甲烯氧基烷氧基基团;残基R.sup.14和R.sup.15以及在公式中未标记特定符号的环上的位置表示任何所需的取代基,这些取代基可以选择性地连接在一起;由虚线标记的两个键表示由虚线标记的键连接的两个碳原子可以通过单键或双键连接在一起;X.sup.-是一个反离子;以及它们至少在R.sup.1、R.sup.7或/和R.sup.13残基之一上被激活的衍生物。这些化合物可用作吸收或荧光染料,特别是作为半抗原/抗体/蛋白质共轭物的标记物,作为激光染料以及作为太阳能收集器的吸收介质。
