Selenophene-Based Heteroacenes: Synthesis, Structures, and Physicochemical Behaviors

On the basis of three new building blocks, dithieno[3,2-b:2′,3′-d]selenophene (tt-DTS), diseleno[3,2-b:2′,3′-d]thiophene (tt-DST), and diseleno[3,2-b:2′,3′-d]selenophene (tt-DSS), four thiophene- and selenophene-based heteroacenes (3a-d) with up to seven

A highly hindered bithiophene-functionalized dispiro-oxepine derivative as an efficient hole transporting material for perovskite solar cells

Dimethoxydiphenylamine-substituted dispiro-oxepine derivative 2,2′,7,7′-tetrakis-(N,N′-di-4-methoxyphenylamine)dispiro-[fluorene-9,4′-dithieno[3,2-c:2′,3′-e]oxepine-6′,9′′-fluorene] (DDOF) has been designed and synthesized using a facile synthetic route. The novel hole transporting material (HTM) was fully characterized and tested in perovskite solar cells exhibiting a remarkable power conversion efficiency of 19.4%. More importantly, compared with spiro-OMeTAD-based devices, DDOF shows significantly improved stability. The comparatively comprehensive solid structure study is attempted to disclose the common features of good performance HTMs. These achievements clearly demonstrated that the highly hindered DDOF can be an effective HTM for the fabrication of efficient perovskite solar cells and further enlightened the rule of new HTM's design.

Oligomeric Perylene Diimide Non-Fullerene Acceptors via Direct (Hetero)Arylation Cross-Coupling Reactions

Oligomeric compounds useful as organic conjugated materials in electronic devices. Oligomeric compounds contain three or more or four or more of certain PDI units bonded to an organic core. The organic core contains one, two or more thiophene rings. The organic core can contain two or more thiophene rings separated by a linker group; two or more thiophene rings directly fused to each other or indirectly fused to each other through an optionally substituted aromatic or non-aromatic carbocylic ring system or an optionally substituted aromatic heterocyclic or non-aromatic heterocyclic ring system; or each of two or more thiophene rings is fused to an aromatic or non-aromatic carbocylic ring system or an aromatic heterocyclic or non-aromatic heterocyclic ring system and the resulting fused rings containing a thiophene ring are each separated by a linker group M. Methods for making oligomeric compounds by direct heteroarylation are provided.

FUSED RING DERIVATIVE AND ORGANIC SOLAR CELL COMPRISING THE SAME

The present invention relates to a condensed cyclic derivative represented by chemical formula 1, and an organic solar cell containing the same. According to an embodiment of the present invention, the condensed cyclic derivative exhibits excellent coating properties by having a hydroxyl group, an alkyl group, an alkoxy group, and a sulfide group as a substituent.COPYRIGHT KIPO 2017
