molecular ordering of semiconducting small molecules comprising a newly designed A(D–A′–D)2 system. The A(D–A′–D)2 small molecules have twodifferentacceptors based on isoindigo and diketopyrrolopyrrole along with tert-butoxycarbonyl (t-Boc) groups and hexyl chains, which improve the solubility of the materials. After simple thermal annealing, the t-Boc groups were removed to allow strong hydrogen bonds

Isoindigos were prepared via a gold‐catalyzed dimerization of 3‐diazooxindoles. Besides a broad substrate scope and functional group tolerance, the reaction also exhibited high efficiency on a gram‐scale reaction.

donor-acceptor type of small molecules was synthesized. Tert-butoxycarbonyl (t-Boc) substituted isoindigo is used as the acceptor unit and oligothiophene derivatives as the donor units. Thermal decarboxylation of small molecules films at 200 °C eliminated the t-Boc side groups. The cleavage of the protecting group formed a variety of N–H …. .O=C hydrogen bonding across the lactam structures of the isoindigo.
