摘要
Light-collecting system contains a coumarin deriv. of the formula (I) (in which T is O or NR4; R4 is H or opt. substd. ar(alk)yl or cycloalkyl; R1 is a C-bound 5- or 6-membered carbo- or heterocycle or an N-bound 5- or 6-membered heterocycle which is rotationally asymmetrical about the coumarin-N-heterocycle bond, these 5- and 6-membered rings have nonionic substits. and can be condensed with an opt. substd. benzene or naphthalene ring; X is -NR2R3 or -OR'2; R2 is H or opt. substd. (cyclo)alkyl or ar(alk)yl; R3 is R2, R6-(Y)n-CO- or R7-(Y)n-SO2-; R6 and R7 are opt. substd. (cyclo)alkyl or ar(alk)yl; Y is NH or O; n is O or 1; R2 and R3, when R3 is R2, together with the N atom can form a 5- or 6-membered heterocycle opt. contg. other heteroatoms and opt. with nonionic substits. and a condensed, opt. substd. benzene or naphthalene ring, or R2 and R3 together are a CHR8- gp.; R8 is opt. substd. (cyclo)alkyl or ar(alk)yl; and R'2 is opt. substd. (cyclo) alkyl, ar(alk)yl or alkenyl)..
