The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

When many of the currently largest chemical companies were founded about 150 years ago,
textile dyes constituted their first products. Interestingly, while most of the utilized colorants …

We report an efficiency of 6.1% for a solution-processed non-fullerene solar cell using a
helical perylene diimide (PDI) dimer as the electron acceptor. Femtosecond transient …

Triplet photosensitizers (PSs) have attracted much attention in recent years, due to the
significance of these kinds of compounds in fundamental photochemistry studies and …

In natural photosynthesis, organisms optimize solar energy conversion through organized
assemblies of photofunctional chromophores and catalysts within proteins that provide …

Singlet fission is a process in which a singlet exciton converts into two triplet excitons. To
investigate this phenomenon, we synthesized two covalently linked 5-ethynyl-tetracene (ET) …

We begin with a general description of the chemical, physical, and electrical properties of
organic semiconductors, OSCs, a class of materials that includes molecular semiconductors …

Perylenediimide (PDI)-based acceptors offer a potential replacement for fullerenes in bulk-
heterojunction (BHJ) organic photovoltaic cells (OPVs). The most promising efforts have …

The crystal structure of N, N-bis (n-octyl)-2, 5, 8, 11-tetraphenylperylene-3, 4: 9, 10-bis
(dicarboximide), 1, obtained by X-ray diffraction reveals that 1 has a nearly planar perylene …
