An optical oxygen sensor which is based on a transfer of electromagnetic energy from a donor to an acceptor is described. Pyrene derivatives of the general formula I wherein R signifies an alkyl group with up to 30 C atoms which is substituted with a hydroxy or amino group or a group of the formula -NH(1-8C alkyl), a group -CH2-OR in which R has the aforementioned significance, a group -OR in which R has the aforementioned significance or a group -R'-O-R'' in which R' signifies an alkylene group, R'' has the above significance of R and R' and R'' together have not more than 30 C atoms and n signifies a whole number of 1-10, are used as the O2-indicators or as the donors. 1-Hydroxymethylpyrene, 1-(11-hydroxyundecyl)pyrene, 1-(11-hydroxyundecyloxymethyl)pyrene and 1-(2-aminoethyl-oxymethyl)pyrene are preferred pyrene derivatives. Perylene derivatives of the general formula II wherein R and n have the aforementioned significance, are used as the acceptors. 3-Hydroxymethylperylene, 11-amino-1-(3-perylene-methoxy)undecane, 3-(2-aminoethyloxymethyl)perylene and 3-(11-hydroxyundecyloxymethyl)perylene are preferred acceptors.
