Abstract
Luminescent solar concentrator (LSC) comprising at least one disubstituted benzoheterodiazole compound of general formula (I), in which: —Z represents a sulfur atom, an oxygen atom, a selenium atom; or an NRgroup in which Ris selected from linear or branched C-C, preferably C-C, alkyl groups, or from optionally substituted aryl groups; —R, Rand R, which are the same or different, represent a hydrogen atom; or are selected from linear or branched C-C, preferably C-C, alkyl groups, optionally containing heteroatoms, optionally substituted cycloalkyl groups, optionally substituted aryl groups, optionally substituted linear or branched C-C, preferably C-C, alkoxyl groups, optionally substituted phenoxyl groups, or —COORgroups or —OCORgroups in which Ris selected from linear or branched C-C, preferably C-C, alkyl groups, or is a cyano group, provided that when the substituents Rrepresents a hydrogen atom, at least one of the substituents Rand Rrepresents an optionally substituted aryl group or an optionally substituted phenoxyl group; —or Rand R, can optionally be linked together so as to form, together with the carbon atoms to which they are linked, a saturated, unsaturated or aromatic cyclic ring or a polycyclic system containing from 3 to 14 carbon atoms, preferably from 4 to 6 carbon atoms, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorus, selenium; —or Rand Rcan optionally be linked together so as to form, together with the carbon atoms to which they are linked, a saturated, unsaturated or aromatic cyclic ring or a polycyclic system containing from 3 to 14 carbon atoms, preferably from 4 to 6 carbon atoms, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorus, selenium; —Rand R, which are the same or different, represent a hydrogen atom; or are selected from linear or branched C-C, preferably C-C, alkyl groups, optionally containing heteroatoms, optionally substituted cycloalkyl groups, optionally substituted aryl groups, optionally substituted linear or branched C-C, preferably C-C, alkoxyl groups, —COORgroups or —OCORgroups in which Ris selected from linear or branched C-C, preferably C-C, alkyl groups, or is a cyano group; or Rand R, can optionally be linked together so as to form, together with the carbon atoms to which they are linked, a saturated, unsaturated, or aromatic cyclic ring or a polycyclic system containing from 3 to 14 carbon atoms, preferably from 4 to 6 carbon atoms, containing one or more heteroatoms such as, for example, sulfur, nitrogen, silicon, phosphorus, selenium.
