Despite numerous organic semiconductors being developed during the past decade, C70 derivatives are predominantly used as electron acceptors in efficient polymer solar cells (PSCs). However, as-prepared C70 mono-adducts intrinsically comprise regiois

To evaluate the effects of substituent bulkiness around a porphyrin core on the photovoltaic properties of porphyrin-sensitized solar cells, long alkoxy groups were introduced at the meso-phenyl group (ZnPBAT-o-C8) and the anchoring group (ZnPBAT-o-C

A series of alkoxycarbonyl-substituted dihydronaphthyl-based [60]fullerene bis-adduct derivatives (denoted as C2BA, C4BA, and C6BA with the alkyl chain of ethyl, n-butyl, and n-hexyl, respectively) have been synthesized to investigate the effects of

We have prepared a push-pull porphyrin with an electron-donating triarylamino group at the β,β'-edge through a fused imidazole group and an electron-withdrawing carboxyquinoxalino anchoring group at the opposite β,β'-edge (ZnPQI) and evaluated th

Water normally exists in hydrogen-bonded environments, but a single molecule of H2O without any hydrogen bonds can be completely isolated within the confined subnano space inside fullerene C60. We isolated bulk quantities of such a molecule by first

In the presence of an active Ir-based catalyst, azulene underwent stepwise borylation with bis(pinacolato)diboron to produce polyborylated products. The reactivity of the ring atoms toward borylation was found to decrease in the following order: 2-po

Azulene-2-boronic acid pinacol ester was conveniently transformed into 2-substituted azulenes bearing carboxyl, tormyl, ester, or amino groups, which are difficult to access by conventional methods. Furthermore, the azulene-2-carboxylic acid thus syn

Directed lithiation of p-tolyl 1-azulenyl sulfone (1) at the 2-position of the azulenyl group was achieved by using lithium 2,2,6,6-tetramethylpiperidide (LTMP). The azulenyllithium thus generated could be efficiently trapped with various electrophil
