Synthesis and characterization of new electron acceptor perylene diimide molecules for photovoltaic applications

A twisted monomeric perylenediimide electron acceptor for efficient organic solar cells

“…Compared with the reported PCEs of PDI monomer-based solar cells, this initial PCE is much higher a) The average PCE value was calculated from five devices for each condition. than that value reported from the two bay-positions substituted PDI monomer-based solar cells [40][41][42][43], and is close to the top values of the PDI monomer-based non-fullerene cells [44,45]. Fig.…”

“…PDI monomers are alternative non-fullerene acceptors. Functionalized monomeric PDI derivatives were generally synthesized with alkyl-chain on the imide position or aliphatic or aromatic substituent on the bay-position [40][41][42][43][44][45]. The modification on the bay region can be of tremendous assistance to make the perylene core twisted, impede intermolecular interactions, and adjust the energy levels of the materials potentially [46][47][48].…”

Perylene diimide dye/layered carbide charge transfer composite: Design, synthesis, and photophysical properties

“…Perylene diimide derivatives (PDIs) are promising and versatile candidates for use in organic photo-electronic applications [3][4][5]. Substitution at bay positions is an effective strategy for designing new functional PDIs [6].…”

A polystyrene bearing perylene diimide pendants with enhanced solid state emission for white hybrid light-emitting diodes

“…While the tendency of PDI for crystallinity or close packing is widely exploited as n-channel materials for organic field effect transistors [14,15], 5 in order to extend the use of PDIs in other optoelectronic applications such as organic photovoltaics [16], LCD color filters [17], fluorescent sensors [18] and solar concentrators [19], researchers have explored different procedures for limiting or preventing PDI aggregation. These include dispersion in a transparent matrix [20], functionalization with bulky substituents [21][22][23][24], "grafting-to" immobilization [25] and copolymerization [26].…”
