LUMINESCENT SOLAR CONCENTRATOR COMPRISING DISUBSTITUTED NAPHTHOTHIADIAZOLE COMPOUNDS

摘要

A luminescent solar concentrator (LSC) comprising at least one disubstituted naphthothiadiazole compound having general Formula (I) : wherein : - R1, R2, R3, R4, R5, R6 and R7, equal to or different from each other, represent a hydrogen atom; or they are selected from linear or branched C1 -C20,preferably C1 -C10, alkyl groups, optionally containing heteroatoms, cycloalkyl groups optionally substituted, aryl groups optionally substituted, linear or branched C1 -C20, preferably C1 -C10, alkoxyl groups, optionally substituted; - or R1 and R2 , 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 carbon atoms, 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 R2 and R3, 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 carbon atoms, 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 R1 and R4, 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 carbon atoms, 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 R5 and R6, 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 carbon atoms, 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 R6 and R7, 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 carbon atoms, 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.
