    • Compound containing a pentalene unit having general formula (I) wherein R 1 and R 2 , equal to or different from each other, are selected from: linear or branched C 1 -C 20 , preferably C 2 -C 12 , alkyl groups, saturated or unsaturated, optionally containing heteroatoms, cycloalkyl groups optionally substituted, linear or branched C 1 -C 20 , preferably C 2 -C 12 , alkoxyl groups, saturated or unsaturated, optionally substituted; or the groups 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 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; R 3 is selected from aryl groups optionally substituted, heteroaryl groups optionally substituted; n is 0 or 1; with the proviso that: when n is 0, X represents a covalent bond and Y represents a sulfur atom (S); when n is 1, X is equal to Y, and represents a CH group, or a nitrogen atom (N). Said compound containing a pentalene unit, as such or after suitable functionalization and polymerization, can be advantageously used in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on both rigid and flexible supports. Said compound containing a pentalene unit can also be advantageously used as a constitutive unit of luminescent solar concentrators (LSCs). Furthermore, said compound containing a pentalene unit can be advantageously used as precursor of monomeric units in the preparation of semiconductor polymers.
    • 含有通式(I)的pentalene单元的化合物,其中R 1和R 2彼此相同或不同,选自:直链或支链C 1 -C 20,优选C 2 -C 12烷基,饱和或不饱和,任选地含有杂原子 ,任选取代的环烷基,直链或支链C 1 -C 20,优选C 2 -C 12烷氧基,饱和或不饱和的,任选取代的; 或者R1和R2基团可以任选地彼此结合,以便与它们所键合的碳原子一起形成含有3至14个碳原子,优选4至6个碳原子的环状或多环体系 饱和的,不饱和的或芳族的,任选地含有一个或多个杂原子,例如氧,硫,氮,硅,磷,硒; R 3选自任选取代的芳基,任选取代的杂芳基; n为0或1; 条件是:当n为0时,X表示共价键,Y表示硫原子(S); 当n为1时,X等于Y,代表CH基团或氮原子(N)。 所述含有柔性单体的化合物本身或经过适当的官能化和聚合之后,可以有利地用于太阳能电池(或太阳能电池),光伏组件(或太阳能电池) 模块),刚性和柔性支撑。 所述含有柔性单元的化合物也可有利地用作发光太阳能集中器(LSC)的组成单元。 此外,含有柔丝单元的所述化合物可有利地用作制备半导体聚合物中单体单元的前体。
