Luminescent solar concentrator (LSC) comprising at least one disubstituted benzothiadiazole compound having general formula (I):
wherein:
- R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 , equal to or different from each other, represent a hydrogen atom; or they are selected from linear or branched C 1 -C 20 , preferably C 1 -C 10 , alkyl groups, cycloalkyl groups optionally substituted, aryl groups optionally substituted, linear or branched C 1 -C 20 , preferably C 1 -C 10 , alkoxyl groups, optionally substituted;
- or R 1 and R 2 , can be optionally bound to each other so as to form, together with the carbon atoms to which they are bound, a cycle or a polycyclic system containing from 3 to 14, preferably from 4 to 6 carbon atoms, saturated, unsaturated, or aromatic, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorous, selenium;
- or R 3 and R 4 , can be optionally bound to each other so as to form, together with the carbon atoms to which they are bound, a cycle or a polycyclic system containing from 3 to 14, preferably from 4 to 6, carbon atoms, saturated, unsaturated, or aromatic, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorous, selenium;
- or R 5 and R 6 , can be optionally bound to each other so as to form, together with the carbon atoms to which they are bound, a cycle or a polycyclic system containing from 3 to 14, preferably from 4 to 6, carbon atoms, saturated, unsaturated, or aromatic, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorous, selenium;
- or R 6 and R 7 , can be optionally bound to each other so as to form, together with the carbon atoms to which they are bound, a cycle or a polycyclic system containing from 3 to 14, preferably from 4 to 6, carbon atoms, saturated, unsaturated, or aromatic, optionally containing one or more heteroatoms such as, for example, oxygen, sulfur, nitrogen, silicon, phosphorous, selenium. |
